Abstract:

Abstract Sustainable transportation is a reflection of the concept of sustainable development in the transportation sector. Sustainable roads protect and augment natural resources and the processes involved. The Department of Public Works, Spatial Planning and Land (PUPRP) of Parigi Moutong Regency is the part responsible for maintaining and repairing roads in Parigi Moutong Regency. The limited budget and the number of roads being managed make the process of determining the priority of road repairs not right on target. This study aims to assist the government in determining road improvement priorities. Therefore, a web-based decision support system for determining road repair priorities was developed. This system was developed using the Weighted Aggregated Sum Product Assessment (WASPAS) method. The results of this study are applications that can help make decisions in determining road repair priorities using the WASPAS method. The results of testing the application using Black Box testing result that all system functions run well and in accordance with the initial design. Furthermore, testing the application using the Delone and McLean Model, the results are very good.

Abstract:

Currently, many roads in Indonesia are damaged. This is due to the presence of large vehicles and large loads that often pass. The more omissions are carried out, the more damaged and severe the road is. The central government and local governments often carry out road repairs, but this problem is often a problem. Damaged roads are indeed many factors, one of which is the road load. The road load is caused by the number of vehicles that carry more than the specified capacity. There are many methods used to monitor roads for road damage. The weighing post is a means used by the government in conducting surveillance. This research is not a proposal to monitor the road, but this is only to create a model for the purpose of detecting heavily or lightly loaded vehicles. This research is to classify using Convolutional Neural Network (CNN) with pre-trained Resnet50. The model generated from the Convolutional Neural Network training process reaches above 90%. Generate Image deep learning algorithms such as the Generative Adversarial Network currently generate a lot of synthetic images. The testing dataset that will be used is generated from style transfer. The model is tested using a testing dataset from the generated style transfer. Style transfer is a method of generating images by combining image content with image styles. The model is pretty good at around 92% for training and 88% for testing, can it detect image style transfer? The Convolutional Neural Network model is said to be good if it is able to recognize the image correctly, considering that the accuracy of the model is very good. One of the reasons why the training model is good but still makes errors during testing, then the image dataset is overfitting

Abstract:

It is generally accepted that road skid resistance should be carefully monitored. However, system-wide testing programs are generally expensive in terms of both manpower and equipment costs. Programs that test only road sections where the road surface is either inadequate or of marginal quality would be more economical than one in which all roads are tested, particularly where a significant proportion of the road surfaces in the system are clearly adequate. This paper examines the potential for using videotaped road inventory data to identify road sections that are either slippery or of marginal quality in terms of skid resistance. It reports on research conducted which examined the ability of individuals to identify inadequate road sections and discriminate these road sections from those with good surfaces by using VHS and super-VHS road inventory videotaped images. Videotaped records of road sections were evaluated by a panel. Their responses were then compared with skid resistance test data. A statistical analysis showed no satisfactory level of agreement between measured data and video evaluations for the VHS records. A second series of tests was conducted using super-VHS technology. The results of the second series of tests showed much better agreement. The research provided promising results and it would appear that videotaped road inventory data could be used as part of a protocol that could be developed to identify the sections that should be field tested as part of a system-wide skid resistance monitoring program.Key words: highway safety, skid resistance, program design, pavement characteristics, video evaluation.

Abstract:

This study was set out to analyze and investigate the damaged surface course of a newly-constructed road pavement within the two years after its completion. Because the idea of sustainable public infrastructure in Taiwan has recently encouraged the use of renewable materials in the design phase, parts of this roads pavement structure is composed of recycled asphalt concrete, renewable agents, disposed construction surplus and the like. Considering the complex relationship between the damaged condition of the road pavement and factors such as its load repetitions, its design, its construction process and management, and road management, this study employed an intelligent vehicle for pavement survey, Benkelman Beam method, GeoGauge, and Ground Penetrating Radar to examine the roads pavement structure. After cross-analyzing the results from the non-destructive testing, certain parts of the road and the possibly-damaged structure of the pavement were sampled for material testing. The results from the material testing indicated that the related mechanical parameters of the road sections sampled by the non-destructive testing were significantly lower than the normal standards. Moreover, the results from the GPR analysis revealed that the water content of the subgrade of the severely-damaged road sections was high. The low loading capacity of the pavement structure was mainly due to the high groundwater water level in the surrounding area and the penetration of the rain into the cracks of the surface course. This study proposes that nondestructive testing can facilitate sampling sections for material testing to better ensure the quality of the construction although random sampling is commonly seen in the standard material testing for acceptance of completed work. In addition, the study suggests that non-destructive testing can be one requirement for the acceptance of completed work in pavement projects with renewable materials to better evaluate the quality of the pavement after its construction.

Abstract:

Abstract The Airbara - Toboali Road Section is a national road located in South Bangka Regency, Bangka Belitung Islands Province. Some segments of this road often experience road damage, although road repairs have been carried out several times to overcome the damage. The subgrade layer is the most important layer in the pavement structure because it functions to withstand all the loads above it. CBR (California Bearing Ratio) is penetration test used to evaluate the subgrade strength of roads and pavement. Therefore, this study aims to investigate the subgrade conditions on the Air Bara – Toboali road section in order to improve road quality. This study uses hand boring testing with 4 sampling points and field CBR testing with the DCP tool. Field CBR samples were taken as many as 30 points every 50 meters from STA 0+000 – STA 1+450. The average CBR value obtained shows that the CBR of this subgrade is in the good category (10.77%). Subgrade conditions per layer, namely at a depth of 0-2 meters the roads have almost the same soil characteristics. However, the soil depth of more than 2 meters in several locations on the road segment has a different character. The results of this investigation are expected to assist road planning so that road quality can improve.

Abstract:

Road traffic can be interpreted as a phenomenon of great complexity, which is not subject to simple laws, and it is often possible to observe paradoxes that contradict intuition or common sense. Road safety is the system property of road transport. Road accidents are an important public health problem. The statistics show that the risk of injury is about 30 times higher in road traffic than in industry. The study of road accidents should be one of the priorities in the field of social research. The paper describes the specificity of road safety as a research object. In particular, attention was paid to theoretical, methodological and research aspects. The key problem of road safety research, which was once included in the reports of the World Bank and OECD, was synthetically discussed.

Abstract:

Scientific research has identified road roughness as a significant factor that contributes to increased vehicle dynamic wheel loads and therefore damage to pavements and bridges. The other factors include vehicle speed and vehicle suspension type. More specifically and regarding road roughness, research has shown that damaging effects are caused by certain wavelengths and features in road profiles and not the overall road roughness. Various methods of classifying road roughness based on the ride quality are available. These methods, though important, are limited in identifying the location of features along road profiles that cause exceptionally high dynamic wheel loads hence damage. It is the development of a methodology for identifying the location of these abnormally high dynamic wheel forces that this thesis addresses. A vehicle-road interaction model was developed for this research. This computer model uses a quarter vehicle model and recorded road profile elevation data to simulate the response of half a vehicle axle (quarter vehicle) driving along a road. 47 road profiles over 17 bridges were measured to run the model. Signal processing techniques developed by electrical and mechanical engineers have been used as an additional tool to road profile analysis. These techniques are very powerful and their application to road profile investigations is significant. Using computer simulation and by combining ride and damage criteria analysis, a methodology of identifying segments of road that induce high dynamic wheel forces and the location of abnormally high dynamic wheel forces has been established.

Abstract:

In areas of seasonal frost, frost susceptibility composed by frost heaving during the winter and thaw softening during the spring is one of the most dangerous phenomenon for transportation, road and railway infrastructure. Therefore, the need for frost protection layer becomes imperative. The purpose of frost protection layer is to prevent frost from penetrating down through the pavement and into the sub-soils. Frost susceptible soils under the road can be cause damages on the roads or other structures due to frost heave or reduced capacity characteristics thaw period. "Frost heave" is the term given to the upwards displacement of the ground surface caused by the formation of ice within soils or aggregates (Rempel et al., 2004). Nowadays in Scandinavia the most common material used in frost protection layer in the pavement structure of roads and in the ballast of the railway tracks are coarse-grain crushed rocks aggregates. Based on the capillary rise, the mechanics of frost heave phenomenon is based on the interaction between aggregates and water, as suggested by Konrad and Lemieux in 2005 that said that the fraction of material below the 0.063 mm sieve for coarse-grained soils must be controlled so as to reduce the sensitivity to frost heave. The study conducted in this thesis project is divided in two parts: - the analysis of the coarse grained aggregates used in frost protection layer in Norway; - the analysis of the frost heave phenomenon in the laboratory under known boundary conditions, through the use of the most widely used method, the frost heave test, in” closed system” (without access of water).

Abstract:

A major challenge in tire, as well as in road engineering, is to understand the intricate mechanisms of friction. Pavement texture is a feature of the road surface that determines most tire-road interactions, and can be grouped into two classes: macro-texture, resulting mainly in the hysteretic component of friction, and micro-texture, resulting in adhesion. If both textures are maintained at high levels, they can help provide sufficient resistance to skidding. The ultimate objective of this research is to develop a physics-based multiscale rubber-road friction model that can predict the effectiveness of the tire as it interacts with the vehicle and the pavement. The model is developed based on sound physics and contact mechanics theories and uses road profile measurements and data measured on various tire compounds. To be able to predict road surface characteristics, it is proven that road surfaces are of fractal nature on given ranges of scale. It is shown that while global fractal quantities fail to classify pavement profiles, a local fractal parameter and three other texture parameters can separate road profiles that have different friction characteristics. Through the implementation of various contact theories and by conducting simulation studies, a methodical understanding of contact mechanics and of the effect of the diverse factors that influence friction is attained. To predict the viscoelastic friction between any given tire tread compound and road, the Nanovea JR25 portable optical profilometer is used to measure the road profiles. To characterize the road profile, the one-dimensional pavement measurements are used to obtain the two-dimensional power spectrum, followed by testing and characterizing the tread compounds (this is being carried out by Bridgestone). This data is used to develop a comprehensive analytical methodology to predict friction. To validate this model, a Dynamic Friction Test apparatus is designed and built. The friction tester enables measurement of the friction between tread compound samples and arbitrary surfaces, at different slip ratios. The correlations between the simulations and both indoor and outdoor experimental results are investigated.

Abstract:

Drivers for sustainability have made it necessary for the construction industry to adapt its traditional processes to become both more efficient and produce less waste. Performance based design and specification in the UK for motorways and trunk roads permits a very flexible approach to pavement design, material selection and performance related testing aimed at utilising materials to their maximum potential. However, it is clear that within the emerging philosophy of using materials that are 'fit for purpose' there are many technical challenges for design and specification. There is a need to develop suitable methods of evaluating materials prior to their being used on site. This project was born out of this requirement, with a particular emphasis on coarse granular materials due to their common role in capping construction and also their unique difficulty for measurement under laboratory conditions due to their large range of particle size. A novel assessment test for coarse capping materials for roads that can be used to indicate their likely short-term in situ performance, under controlled laboratory conditions before construction on site, has been developed during this research programme. Key findings relating to the behaviour of coarse capping materials, the use of stiffness measuring devices and variables that influence the measurement of composite stiffness are discussed in detail. The research highlights the necessity for adequate drainage and protection of foundation materials against increase in water content. When adopting a performance specification the timing of the pavement assessment is critical, both on site and in the laboratory. The performance measured on site should perhaps only be considered as a 'snapshot' relating to the stress state in the material at the time of testing.

Abstract:

A ground vehicle mounted aerodynamic testing apparatus has been identified as a candidate concept for a low-cost alternative to traditional techniques. This dissertation explores the feasibility of a ground vehicle based system by identifying physical and practical issues facing such a system. The focus is on the two most important physical problems facing the concept. These are: the ride dynamics of a vehicle as it traverses a road, and the extent of the distortion of the airflow around a vehicle. Each of these problems is quantified using approximate methods in order to estimate their influence on the testing of the aircraft in order to determine if the concept is workable.

Abstract:

Many ageing road bridges, particularly timber bridges, require urgent improvement due to the demand imposed by the recent version of the Australian bridge loading code, AS 5100. As traffic volume plays a key role in the decision of budget allocations for bridge refurbishment/ replacement, many bridges in low volume traffic network remain in poor condition with axle load and/ or speed restrictions, thus disadvantaging many rural communities. This thesis examines an economical and environmentally sensible option of incorporating disused flat rail wagons (FRW) in the construction of bridges in low volume, high axle load road network. The constructability, economy and structural adequacy of the FRW road bridge is reported in the thesis with particular focus of a demonstration bridge commissioned in regional Queensland. The demonstration bridge comprises of a reinforced concrete slab (RCS) pavement resting on two FRWs with custom designed connection brackets at regular intervals along the span of the bridge. The FRW-RC bridge deck assembly is supported on elastomeric rubber pads resting on the abutment. As this type of bridge replacement technology is new and its structural design is not covered in the design standards, the in-service structural performance of the FRW bridge subjected to the high axle loadings prescribed in AS 5100 is examined through performance load testing. Both the static and the moving load tests are carried out using a fully laden commonly available three-axle tandem truck. The bridge deck is extensively strain gauged and displacement at several key locations is measured using linear variable displacement transducers (LVDTs). A high speed camera is used in the performance test and the digital image data are analysed using proprietary software to capture the locations of the wheel positions on the bridge span accurately. The wheel location is thus synchronised with the displacement and strain time series to infer the structural response of the FRW bridge. Field test data are used to calibrate a grillage model, developed for further analysis of the FRW bridge to various sets of high axle loads stipulated in the bridge design standard. Bridge behaviour predicted by the grillage model has exemplified that the live load stresses of the FRW bridge is significantly lower than the yield strength of steel and the deflections are well below the serviceability limit state set out in AS 5100. Based on the results reported in this thesis, it is concluded that the disused FRWs are competent to resist high axle loading prescribed in AS 5100 and are a viable alternative structural solution of bridge deck in the context of the low volume road networks.

Abstract:

Internal consistency reliability and validity were established for a new 31 item Imagery Manipulation Scale. Previous attempts to correlate subjectively rated control of visual imagery with tests of spatial ability have been unsuccessful. However, no attempt to construct a subjectively rated control of imagery scale was located which tried to establish internal consistency reliability and both content and construct validity. Further, no research was located in which subjects were requested to rate their imagery ability utilized during the performance of the actual spatial tasks used to try to establish validity. A new scale of subjectively rated control of imagery was devised in which subjects were requested to rate their imagery while solving spatial tasks which involved visualizing the manipulation of geometric forms. Content validity was established by analyzing the transformation involved while solving the spatial problems. Internal consistency reliability for the 31 item scale was established across two samples. Validity was established with the second sample (100 university students: 26 male and 74 female). The task utilized to provide validity could be objectively scored, and was made up of four spatial subtests, which were adapted from the Vandenberg and Kuse Mental Rotations Test, the Kosslyn Directions Test, performed in both the forward and backward direction, and a block task utilized by Snyder. A convergent and discriminant validity analysis established construct validity. Further, the hypotheses of three investigators, Kosslyn, Shepard and his colleagues, and Snyder, were supported by the results of the present investigation, thus substantiating the conclusion that reported control of imagery processing can be operationalized with performance scores on spatial ability tasks.

Abstract:

The continued use of structural plastics in consumer products, industry, and transportation represents a potential source for durable, long lasting, and recyclable roadways. Costs to dispose of reinforced plastics can be similar to procuring new asphalt with mechanical performance exceeding that of the traditional road surface. This project examines improved material development times by leveraging advanced computational material models based on validated experimental data. By testing traditional asphalt and select carbon and glass reinforced composites, both new and recycled, it is possible to develop a finite element simulation that can predict the material characteristics under a number of loads virtually, and with less lead time compared to experimental testing. From the tested specimens, composites show minimal strength degradation when recycled and used within the asphalt design envelopes considered, with an average of 49% less wear, two orders of magnitude higher compressive strength, and three orders for tensile strength. Predictive computational analysis using the validated material models developed for this investigation confirms the long-term durability.

Abstract:

Traditionally, the interactions of drugs and toxicants with human tissue have been investigated in a reductionist way—for example, by focusing on specific molecular targets and using single-cell-type cultures before testing compounds in whole organisms. More recently, “systems biology” approaches attempt to enhance the predictive value of in vitro biological data by adopting a comprehensive description of biological systems and using computational tools that are sophisticated enough to handle the complexity of these systems. However, the utility of computational models resulting from these efforts completely relies on the quality of the data used to construct them. Here, we propose that recent advances in the development of bioengineered, three-dimensional, multicellular constructs provide in vitro data of sufficient complexity and physiological relevance to be used in predictive systems biology models of human responses. Such predictive models are essential to maximally leveraging these emerging bioengineering technologies to improve both therapeutic development and toxicity risk assessment. This brief outlines the opportunities presented by emerging technologies and approaches for the acceleration of drug development and toxicity testing, as well as the challenges lying ahead for the field.

Abstract:

This report describes the full-scale evaluation of prototype submersible matting systems (SUBMAT) at a test site at the US Army Engineer Research and Development Center’s Vicksburg, Mississippi, site. The SUBMAT prototypes were designed to bridge the gap between high and low tide at a beach interface to enable 24-hour operation at an expeditionary watercraft landing site. This phase of the SUBMAT prototype development was intended to determine prototype system durability by applying military vehicle loads representing a combat brigade insertion across a littoral zone. The two mat systems evaluated in this study were the PYRACELL Road Building System (PRBS) and a basaltic rebar mat system. The results of the study showed that the PRBS system was able to sustain 1,000 Medium Tactical Vehicle Replacement, 350 Heavy Expanded Mobility Tactical Truck, and over 150 M1A1 main battle tank passes without significant damage. The basaltic rebar mat failed early in the test and was removed from further consideration for the SUBMAT application. Observations and lessons learned from this phase of the prototype PRBS development will be used to improve the PRBS design and modify its installation procedures for improved efficiency.
