Abstract:
The structure-borne noise while the vehicle passing across the bridge expansion joint is the main source of urban bridge noise. In order to control this noise pollution, 20 bridges including three types of typical expansion joints in Ningbo City were selected, and the noises were measured while vehicle passed across the bridge expansion joints. The measured results are expressed by the Z-weighted sound pressure level, which kept the effect of the low-frequency noise. Then the influence factors of this noise are discussed. The results show that: (1) The sound pressure while vehicle on the bridge expansion joints is much greater than that on the normal road or mid-span of the bridges, which results in significant environmental noise pollution; (2) The wider the gap of the bridge expansion joints, the greater the noise level; (3) The noises produced by the modular expansion joints and comb-plate expansion joints are greater than that from the single-gap expansion joints.

Abstract:
Joints between segments in cantilever casting concrete bridges require special attention in design and construction. These joints introduce discontinuity in the bridge; furthermore weaken the connection stiffness and strength of corresponding section, which may lead to excessive downwarping of bridge. Experiments were conducted to assess the shear stiffness of segmental joints section. The parameters studied included monolithic non-joints, joints roughened, joints roughened with shear-key. It was found that the shear stiffness of jointed section is largely lower than that of non-jointed section; however, the shear-key can effectively enhance the shear strength and especially shear stiffness of the joints section. Measures are proposed for shear-key design, and may provide a rational basis for the design of cantilever casting concrete bridges.

Abstract:
Bridges are hinges of city road and railway, which play an important function in national economy. The changes of temperature affect the length of the highway bridge beams, so the bridge should be equipped with the expansion joint device. When vehicles pass the bridge, dust flies up and clogs the gap of the bridges. The bridge expansion joints should be cleaned in time. The main task of this project is to study a kind of device used to clean the bridge expansion joints, which including two parts: the cleaning system and vacuum dust removal system. First, we use the sweeping wheels to loose dust, then the air-blower to blow away the dust. The optimization of vacuum dust removal system was discussed in this paper. Especially, the Cyclone dust removal device works well. The machine is of higher productivity, wide application, low energy consumption, simple structure compared with similar equipments.

Abstract:
The Lacey V. Murrow Bridge (LVM Bridge) is a 2013-m-long floating bridge on Interstate 90 across Lake Washington in Seattle, Washington. Single-support-bar, swivel-joist modular bridge expansion joint systems are located at each end of the bridge between the shore approach spans and the floating pontoons. These joints were designed for 960 mm of longitudinal movement as well as horizontal and vertical rotations caused by wind, wave, temperature, and changes in lake level elevation. A similar joint in an adjacent floating bridge had experienced premature fatigue cracking at welded attachment details because of low fatigue strength. For the LVM Bridge the joint components were fatigue tested and designed by using fatigue limit-states loads, resulting in welded attachment details with improved fatigue strength. In addition, a stiffer center beam and reduced center-beam span lengths produced lower fatigue stress ranges. Joint movements and rotations, fatigue design methodology, results of dynamic analyses, field measurements of the dynamic response, and construction details are described. The total cost of the LVM joints was 1 percent of the final bridge cost. The Washington State Department of Transportation required a 5-year guarantee for the LVM joints. These are the largest modular bridge expansion joints in the United States to be tested and designed for fatigue.

Abstract:
It is well recognized that leaking expansion joints at the ends of bridge decks have led to the premature deterioration of bridge components. The elimination of these maintenance-prone joints not only yields immediate economic benefits but also improves the long-term durability of bridges. In Ontario, Canada, “jointless” bridges have been used for many years. Recently, the use of two main types of these bridges has increased dramatically. The first type is an “integral abutment” bridge that comprises an integral deck and abutment system supported on flexible piles. The approach slabs are also continuous with the deck slab. The flexible foundation allows the anticipated deck movements to take place at the end of the approach slab. Control joint details have been developed to allow movements at this location. The second type is a “semi-integral abutment” bridge that also allows expansion joints to be eliminated from the end of the bridge deck. The approach slabs are continuous with the deck slab, and the abutments are supported on rigid foundations (spread footings). The superstructure is not continuous with the abutments, and conventional bearings are used to allow horizontal movements between the deck and the abutments. A control joint is provided at the end of the approach slab that is detailed to slide in between the wing walls. Some of the design methods and construction details that are used in Ontario for integral and semi-integral abutment bridges are summarized. A review of the actual performance of existing bridges is also presented.

Abstract:
AbstractA “rock bridge”, defined as the closest distance between two joints in a rock mass, is an important feature affecting the jointed rock mass strength. Artificial jointed rock specimens with two parallel joint fractures were tested under uniaxial compression and numerical simulations were carried out to study the effects of the inclination of the rock bridge, the dip angle of the joint, rock bridge length, and the length of joints on the strength of the jointed rock mass. Research results show: (1) When the length of the joint fracture, the length of the rock bridge, and the inclination of the rock bridge stay unchanged, the uniaxial compressive strength of the specimen gradually increases as the inclination of the joint fracture increases from 0°to 90°. (2) When the length of the joint fracture, the length of the rock bridge, and the inclination of the joint fracture stay unchanged, the uniaxial compressive strength of the specimen shows variations in trends with the inclination of the rock bridge increasing from 30° to 150° (3). In the case when the joint is angled from the vertical loading direction, when the dip angle of the joint fracture, the inclination of the rock bridge, and the length of the rock bridge stay unchanged, the uniaxial compressive strength of the specimen gradually decreases with an increasing length of joint fracture. When the dip angle of the joint fracture, the inclination of the rock bridge, and the length of the joint fracture stay unchanged, the uniaxial compressive strength of the specimen does not show a clear trend with an increase of the length of the rock bridge.

Abstract:
In general, most highway bridges are constructed using prestressed concrete or steel girders. Mechanical joints are provided at the end of each span, to allow for the expansion of the bridge deck due to shrinkage of concrete, thermal effects, and deflections, among others. Smooth riding ability, low noise, wear resistance, and water tightness should be provided by expansion joints. In recent times, the increased traffic volume, along with heavier vehicle movements, adversely affects the performance of expansion joints in the bridge girder, causing a possible failure in one of the above-mentioned mechanisms. The deterioration of the expansion joint may result in leakage of water, concrete cracking, and potential problems in the underlying substructure. In this paper, we study the pier-pier cap connections in integral bridges subjected to thermal and seismic loads using analytical methods and experimental tests.

Abstract:
The mechanical behavior of the steel–concrete joints in a composite bridge was investigated. Pull-out tests on eight specimens were carried out to evaluate the connection performance of Perfobond rib shear connectors (PBL shear connectors). In addition, static load tests were conducted on three composite joint specimens with a scale of 1/2 in a composite truss bridge. The crack load, load–displacement curves, strain distribution, and the joint stiffness were obtained from the composite joint to analyze the mechanical behavior of steel–concrete joints. The experimental results show that the embedded depth plays an important role in the ultimate bearing capacity and the deformation of PBL shear connectors and could even change the failure mode. Based on the test results of composite joints, the displacement increased almost linearly with the horizontal load on the concrete chord. There was no evident failure, and large deformation occurred in composite joints. In addition, the ultimate loads obtained from three composite joint specimens were greater than 2.93 times the design load (2050 kN). These investigated composite joints had excellent bearing capacity (above 6000 kN). This study will provide an experimental reference for the design of steel–concrete joints for composite truss bridges.

Abstract:
Surface subsidence caused by mining operation can amount to several meters, which is far above the standard value in design code. Once mining collapse occurs, bridges’ large deformation can result in bridge disasters. In order to prevent bridge disasters in mining area, bridge disaster characteristics in different districts in working face of mining are analyzed on the base of large deformation regularity of ground. A method of avoiding location of piers at inferior fovea and superior fovea in the migrated basins is presented to reduce the deformation of bridges on condition that subsidence area can’t be bypassed. And smooth joints between road and bridge are also advised to be designed to reduce staggering of joint and cracking. Moreover, applicability of several prevention methods for bridge disasters is demonstrated based on different bridge design and foundation treatments in mining area. The results show that geological disasters of bridges can be prevented by choosing reasonable foundation and structure type, which provides reliable basis for bridge construction in mining area.

Abstract:
In accelerated bridge construction (ABC), prefabricated bridge deck elements are merged using “closure joints.” Because of the cast-in-place nature of closure joints that are expected to go into service rapidly and problems observed for some types of closure joints, there have been some concerns about their long-term durability. This has necessitated the need for monitoring the condition of ABC closure joints using non-destructive testing (NDT) methods. Closure joints contain unique features and details that sets them apart from conventional deck panels. This requires a special treatment of closure joints when it comes to selecting the appropriate NDT technique for their health monitoring. A clear guideline for selecting an applicable NDT method for various types of closure joints has not been developed yet. For this purpose, an investigation was carried out in the Accelerated Bridge Construction University Transportation Center (ABC-UTC) at Florida International University. This paper summarizes the result of this investigation. It includes reviews of all relevant NDT methods for applicability to ABC closure joints and efforts for categorizing closure joints according to joint features that affect the use of NDT. Since the applicability of NDT methods heavily depend on the type of expected anomaly to be detected and its root causes, all potential defects and types of damage were identified and investigated using a damage sequence tree (DST). Consequently, damage etiology for ABC closure joints were established using fault tree analysis (FTA). Finally, a quantitative statistical survey was used to substantiate the selection of the NDT methods that were most applicable to the health monitoring of ABC bridges containing closure joints. The results presented in this paper can be used by bridge owners and consultants as an effective and practical guide for the selection of NDT methods for monitoring the health of ABC closure joints.

Abstract:
Reversed cyclic loading tests were carried out on a number of specimens including five half-scale reinforced concrete bridge columns with one and two-way hinges at the column-footing connection, a half-scale column with lap-spliced dowels at its base and a quarter-scale outrigger beam-column-joint. The test specimens had details typical of bridges designed and built in Montreal in the 1960's. These tests highlighted the design and detailing deficiencies and demonstrated the poor seismic performance of the "as-built" structural elements. Procedures and guidelines for retrofitting were developed for moderate seismic regions and were applied to the test specimens. The reversed cyclic loading responses of these retrofit specimens demonstrated the improved strength, ductility and energy dissipation of the retrofits.
Analytical techniques are described which result in accurate response predictions for both the "as-built" and the retrofit elements. A series of compression tests on concrete hinges permitted the development of a model to assess the influence of confinement on the stress-strain characteristics of the hinge region concrete. The response predictions included the effects of confinement of concrete hinges, bond slip, shear distress, presence of lap splices and poor anchorage details. Static analyses were performed according to the 1996 Canadian Highway Bridge Design Code (CHBDC) to determine the seismic responses of prototype structures and to determine if retrofit is required. Non-linear dynamic analyses were performed with three input ground motions to predict the responses of the "as-built" structures and to assess the performance of the retrofit structures. These analyses identified the deficient structural systems and demonstrated that the retrofit techniques developed were effective in significantly improving the seismic responses.

Abstract:
A set of experimental tests were performed at Virginia Tech to investigate transverse joints and blockouts on full depth concrete bridge deck panels. The joints were designed on a deck replacement project for a rural three span continuous steel girder bridge in Virginia. Two cast-in-place and four post-tensioned joints were designed and tested in cyclical loading. Each joint was tested on a full scale two girder setup in negative bending with a simulated HS-20 vehicle. The blockouts were built as hollow concrete rings filled with grout and left to shrink under ambient conditions. Thirteen combinations of different surface conditions and grouts were designed to test the bond strength between the materials. The strain profile, cracking patterns, and ponding results were measured for all specimens. A finite element analysis was performed and calibrated with the laboratory results. The cast-in-place joints and the two post-tensioned joints with 1.15 MPa (167 psi) of initial stress experienced cracking and leaked water by the end of the tests. The two post-tensioned joints with 2.34 MPa (340 psi) initial stress kept the deck near a tensile stress of 1.5â (f'c) and performed the best. These transverse joints did not leak water, did not have full depth cracking, and maintained a nearly linear strain distribution throughout the design life. Full depth deck panel may be effectively used on continuous bridges if a sufficient amount of post-tensioning force is applied to the transverse joints. The finite element model provides a design tool to estimate the post-tensioning force needed to keep the tensile stresses below the cracking limit. The blockouts with a roughened surface or an epoxy and a grout equivalent to Five Star Highway Patch grout had the highest bond stresses, did not leak water, and had smaller cracks at the grout-concrete interface than the control samples. A minimum bond strength of 2.5â (f'c) was maintained for all of the specimens with a grout equivalent to Five Star Highway Patch. A pea gravel additive in the grout reduced shrinkage and reduced the bond strength. The finite element model provides a design tool to estimate cracking at the grout-surface interface.

Abstract:
The Accelerated bridge construction (ABC) techniques are gaining popularity among the departments of transportation (DOTs) due to their reductions of on-site construction time and traffic delays. One ABC technique that utilizes precast deck panels has demonstrated some advantages over normal cast-in-place construction, but has also demonstrated some serviceability issues such as cracks and water leakage to the transverse joints. Some of these problems are addressed by applying longitudinal prestressing. This thesis evaluates the service and ultimate capacities in both flexure and shear, of the finite element models of the post-tensioned system currently used by Utah Department of Transportation (UDOT) and a proposed curved-bolt system to confirm the experimental results. The panels were built and tested under negative moment in order to investigate a known problem, namely, tension in the deck concrete. Shear tests were performed on specimens with geometry designed to investigate the effects of high shear across the joint. The curved-bolt connection not only provides the necessary compressive stress across the transverse joint but also makes future replacement of a single deck panel possible without replacing the entire deck. Load-deflection, shear-deflection curves were obtained using the experimental tests and were used to compare with the values obtained from finite element analysis. In flexure, the ultimate load predicted by the finite element model was lower than the experimental ultimate load by 1% for the post-tensioned connection and 3% for the curved-bolt connection. The shear models predicted the ultimate shear reached, within 5% of the experimental values. The cracking pattern also matched closely. The yield and cracking moment of the curved-bolt connection predicted by the finite element model were lower by 13% and 2%, respectively, compared to the post-tensioned connection in flexure.

Abstract:
<p>The integral expansion joint is a novel bridge expansion joint for bridges and viaducts with three breakthrough characteristics: (1) allows continuous driving, therefore (i) reducing the risk of accidents and increases safety for the road user and their vehicles; (ii) mitigating noise (the bump effect from conventional joints); (2) avoids the filtering of water, detritus and de-icing salts reducing conservation costs (opex and capex) of bridge substructures; (3) has a long-service life vis-à-vis conventional joints, therefore: (i) reducing the maintenance expenditure in bridge joints (life-cycle cost analysis); (ii) reducing traffic cuts and diversions, relevant for toll road operators where there is payment for - or penalties due to lack of – availability and (iii) reducing potential management liability due to improper maintenance. At an affordable supply and installation cost - aligned to conventional joints -, the integral expansion joint aims to solve a well-documented and historical problem in Structural Engineering, strengthening the most vulnerable part of any bridge and road surface. It can be prefabricated or manufactured in situ, implemented in all kind of bridges (new or rehabilitation), in any geography (thermal range), regardless of length of the deck or skewness, and in any material (concrete or metal).</p>

Abstract:
<p>The New York metropolitan area is a treasure trove of spectacular bridges – structures of great cultural significance and remarkable engineering value. Many of these bridges are very long, with long main spans, and thus require expansion joints that can accommodate correspondingly large movements at each end. The challenges associated with meeting the expansion joint needs of such structures are illustrated with reference to iconic bridges including the Verrazano Narrows Bridge, the Bayonne Bridge and the new Tappan Zee Bridge. The paper thus illustrates the importance of suitably engineered solutions for key component requirements in creating and maintaining the extraordinary structural heritage of a city like New York.</p>

Abstract:
<p>A bridge’s expansion joints will almost certainly have to be replaced several times during the course of the bridge’s life, often causing great disruption to traffic and significant expense to the owner – impacts which should, of course, be minimised. The choice of expansion joint selected to replace an old joint strongly influences the expense and disruption caused by replacement works, not only for the current replacement project but also for the next one in the future. Therefore, the way in which joint replacement works are to be carried out, and in particular the type of joint to be used, warrants careful consideration by the responsible engineers.</p>

Abstract:
Bridge expansion joints are key structural components that are subjected to very demanding dynamic loading. Even though modern expansion joints are being continuously developed and improved, they are generally still much less robust and less durable than the main structure. Therefore, replacement of expansion joints is commonly required in the maintenance of our transportation infrastructure. In carrying out such replacement work, the impacts on traffic and on the bridge’s superstructure should be minimised, for economic and sustainability reasons. This paper presents various expansion joint replacement methods which minimise such impacts, for a wide range of scenarios and movement requirements. The methods described cover single gap joints, sliding finger joints and modular joints – which, where appropriate, retain and use elements of suitably designed existing joints, thus optimising the replacement process in various respects.

Abstract:
<p>An appropriate design and correct installation of expansion joints are key crucial for the costs and the life span of the entire structure. As no joint types have a life expectancy similar to the life span of the structure (100-120 years), focus needs to be on choosing joint types with minimal maintenance costs combined with the lowest number of and simplest solution for exchange.<p> Many considerations must be taken when choosing types of expansion joints for a new or existing bridge. Most importantly, the functional requirements like movement capacity, traffic volume and type, noise emission etc. must be observed.<p> The details of the joint type and the details of the bridge area around the expansion joints are important as well considering maintenance costs and ultimately the life span of the bridge.<p> Cases with the most common types of expansion joints are used to look at challenges with life span, maintenance, observation of faults and leaks and consequential damages.<p> New editions of flexible plug joints including new basic materials have reached market in the last couple of years. Instead of the traditional bituminous materials the new expansion joint is ETA approved based on polyurethane. Basic material characteristics are described alongside the detailed geometry and installation options. Material requirements in the ETAG 032-3 Flexible Plug Joints are also described.<p> In November 2017 new general work descriptions for flexible plug joints were published. Requirements and expectations for life span are discussed. Furthermore, the first experiences with the incorporation of polymeric plug joints are evaluated focusing on projecting and execution related challenges.

Abstract:
<p>A much-improved type of flexible plug expansion joint has been developed, with a polyurethane surface, which offers a number of substantial advantages over the traditional bituminous type. The <i>Polyflex®Advanced PU </i>expansion joint offers all the benefits of the asphaltic plug joint, including smooth, safe, low-noise surface, great adaptability and easy installation. However, it overcomes numerous disadvantages and challenges that have always plagued asphaltic plug joints. It offers greatly improved strength, elasticity and durability, resulting in much less maintenance and far more reliable watertightness. The joint’s material offers consistent behaviour at both high and low temperatures, and excellent resistance against rutting. And installation is also far easier and less prone to error, with the two-component compound being mixed at ambient temperatures. For these reasons and others, this joint should be considered for use in bridge construction and, in particular, in bridge maintenance – as demonstrated by successful experience around the world in very varying climates and environments. This paper covers the extensive testing conducted at several independent testing institutes and the significant features and benefits of the system, and presents sample installations.</p>

Abstract:
<p>The application of asphaltic plug joints (APJs) for road bridges has spread worldwide. The APJ consists of polymer modified asphalt binder mixed with selective aggregates filled in the cut-out centred over the gap between bridge span ends or between the bridge deck and abutment. APJs have the advantages of being watertight and free of debris, providing a smooth seamless riding surface through the whole bridge deck for vehicles to pass over with less bump and impact. They are simple, easy, and quick to install. Nevertheless, APJs have some major disadvantages. They are soft, pliable, and weak at higher temperatures. Thus, they can deteriorate severely well in advance of their intended design life. This paper presents a new joint type, i.e. the steelframe reinforced asphaltic plug joint (SRAPJ), modified from the APJ with innovative steelframe reinforcement embedded inside it to enhance its strength and durability. The steelframe has enough vertical stiffness to match the bridge deck and enough longitudinal deformation capacity to accommodate bridge movements from thermal variations and vehicular actions. An experimental application of SRAPJs in a highway bridge and discussion on their performance are also presented. Finally, suggestion for future improvement is proposed.</p>

Full text
Abstract:
Numerous extant studies are dedicated to enhancing the safety of active transportation modes, but very few studies are devoted to safety analysis surrounding transit stations, which serve as an important modal interface for pedestrians and bicyclists. This study bridges the gap by developing joint models based on the multivariate conditionally autoregressive (MCAR) priors with a distance-oriented neighboring weight matrix. For this purpose, transit-station-centered data in Los Angeles County were used for model development. Feature selection relying on both random forest and correlation analyses was employed, which leads to different covariate inputs to each of the two jointed models, resulting in increased model flexibility. Utilizing an Integrated Nested Laplace Approximation (INLA) algorithm and various evaluation criteria, the results demonstrate that models with a correlation effect between pedestrians and bicyclists perform much better than the models without such an effect. The joint models also aid in identifying significant covariates contributing to the safety of each of the two active transportation modes. The research results can furnish transportation professionals with additional insights to create safer access to transit and thus promote active transportation.

Abstract:
In February 2021, a group from MASTS, Environmental Interactions of Marine Renewables (EIMR) and Marine Scotland began exploring options for a joint event on marine energy science and policy development. The original concept was to bridge the gap between events that each group would normally arrange ‘in person’ and the virtual world in which we were all currently existing. Encouraged by the online support and experience available from MASTS, a steering group decided to arrange a workshop. In order to straddle our interests, the starting point was the capacity of the North Sea to deliver renewable energy. We wanted to include emerging science and the timing of the review of Scotland’s National Marine Plan provided an excellent context. We sought to deliver a wide range of content but encourage participant conversation. We aimed for a range of speakers delivering 7-minute recorded talks. Talks included findings from funded research, ongoing projects, and some emerging thinking across the science policy interface for marine planning. Marine energy was interpreted in the widest of senses, but the main focus was on offshore wind in UK waters, with particular detail about Scotland.
