Abstract:
Users of bridges and tunnels are generally concerned about the aging of these structures. Periodic inspections are necessary to keep old bridges and tunnels healthy. Inspection engineers must approach the inspection points as close as possible by mobile elevating of the work platform for close visual inspection of lining concrete. The inspection of a road tunnel particularly requires traffic regulation. Furthermore, it takes much time to perform visual inspection and hammering test for the vast area. Moreover, the inspection results have variations by inspectors. We propose an “Inspection Vehicle” for inspection of tunnel lining concrete by a new technology for infrastructure maintenance. This study reports the finding on element technology of an inspection vehicle and applies a tunnel inspection test.

Abstract:
While the durability of concrete structures is greatly influenced by many factors, previous studies typically considered only a single durability deterioration factor. In addition, these studies mostly conducted their experiments inside the laboratory, and it is extremely hard to find any case in which data were obtained from field inspection. Accordingly, this study proposed an Adaptive Neurofuzzy Inference System (ANFIS) algorithm that can estimate the carbonation depth of a reinforced concrete member, in which combined deterioration has been reflected based on the data obtained from field inspections of 9 buildings. The proposed ANFIS algorithm closely estimated the carbonation depths, and it is considered that, with further inspection data, a higher accuracy would be achieved. Thus, it is expected to be used very effectively for durability estimation of a building of which the inspection is performed periodically.

Abstract:
In many material processing and storing plants an inspector performs during some reference time interval, e.g. one year, a number of inspections because it can not be excluded that the plant operator acts illegally by violating agreed rules, e.g., diverts valuable material. The inspections guarantee that any illegal action is detected at the earliest inspection following the beginning of that illegal action. We assume that the inspector wants to choose the time points for his inspections such that the time which elapses between the beginning of the illegal action and its detection is minimized whereas the operator wants to start his illegal action such that the elapsed time is maximized. Therefore, this inspection problem is modelled as a zero‐sum game with strategies and payoffs as described. Depending on the concrete situation the start of the illegal action and the inspections can take place either at a finite number of time points or at every time point of a reference period. The first case can be modelled as a zero‐sum game with finite pure strategy sets while the latter one leads to a zero‐sum game with infinite pure strategy sets and discontinuous payoff kernel.

Abstract:
The limitations of the standard two-year interval for the visual inspection of bridges required by the U.S. National Bridge Inspection Standards have been well documented, and alternative approaches to bridge inspection planning have been presented in recent literature. This paper explores a different strategy for determining the interval between inspections and the type of inspection technique to use for bridges. The foundational premise of the proposed approach is that bridge inspections are conducted to increase knowledge about the bridge’s current condition, and therefore, are only required when uncertainty about the knowledge of the bridge condition is too high. An example case of a reinforced concrete bridge deck was used to demonstrate how this approach would work. The method utilized deterioration models for predicting corrosion and crack initiation time, considering the uncertainty in the models’ parameters. Bridge inspections were used to update the current condition information and model parameters through Bayesian updating. As this paper presents a new idea for inspection planning, not all of the data or models necessary to fully develop and validate the approach currently exist. Nonetheless, the method was applied to a simulated example which demonstrates how the timing and means of bridge inspection can be tailored to provide the required data about individual bridges needed for effective bridge management decision making.

Abstract:
Regular safety inspections are an important guarantee to ensure the high-quality operation of concrete structures of tunnels. The Chinese West-east Gas Pipeline Project is large in scale and complex in construction environment. These tunnels are equipped with gas pipelines, and the concrete structural defects of the tunnels are continuously exacerbated during the long-term operation. There are few studies on the safety evaluation methods of concrete structures of gas tunnels. Based on the characteristics of the operation of the gas tunnels, this paper proposes the establishment of a structural safety comprehensive inspection system from the following seven aspects, that is, the void between the concrete lining and surrounding rock, the strength of the concrete lining, the thickness of the protective layer of the reinforced concrete lining, the carbonization depth of the concrete lining, the deformation of the tunnel section, the cracks in the concrete lining, and the auxiliary concrete structure of the tunnel. In addition, a corresponding quantitative determination method and safety level classification standard are established. Based on the fuzzy mathematics theory and a structural safety comprehensive inspection system, a five-level safety evaluation method for tunnel concrete structures is proposed. Finally, a comprehensive inspection and evaluation were carried out for a tunnel running across the mountain.

Abstract:
Over the last several decades, many concrete tunnels have been constructed for roads, highways, and railways. For safety in concrete tunnels, periodic inspections have been conducted using nondestructive testing technologies and techniques. However, nondestructive tests cannot replace visual inspection because of their slow and complicated procedures. For this reason, their use has been limited to precision inspections. Visual methods of assessment also require significant time commitments, and they produce subjective results regarding measured crack data. This study proposes an inspection system for the rapid measurement of cracks in tunnel linings and provides an objective method for assessing crack data for safety purposes. The system consists of both image data acquisition and analysis systems. The acquisition system takes images with charge-coupled device (CCD) line-scan cameras. The analysis system extracts crack information from the acquired images using image processing. Measured crack information includes the thickness, length, and orientation of cracks. To improve the accuracy of crack recognition, the geometric properties and patterns of cracks in concrete structures should be applied to image processing. This proposed system was verified through a series of experiments in both laboratory and field environments. Key words: crack, inspection, image processing, tunnel lining, tunnel safety.

Abstract:
The service life of any concrete marine structure is influenced by the physical condition of both the above water and below water portions of structure. This requires implementing an adequate inspection, maintenance, and repair program for the entire structure. To develop an effective maintenance and repair program for the submerged portion of the structure, the causes and extent of concrete distress or deterioration must be clearly understood. This requires a selective underwater condition survey, using a range of in-situ and laboratory testing and inspection techniques, to obtain the necessary information to assess the condition of the submerged portion of the structure. The cause and extent of deterioration, site logistics, and the clients needs will dictate the methods of inspection and repair. Recent developments in concrete admixtures has made it possible to place higher quality concrete suitable for underwater repairs. This thesis provides a summary of the most common forms of concrete distress found in a marine environment, along with a state-of-the-art review of existing and recently developed underwater inspection and repair techniques.
In addition, four case studies are presented to illustrate the application of the above knowledge. The first case study describes the special aspects of underwater repairs to a concrete storm surge barrier damaged during construction. The second case study summarizes the procedures used for repairing a cracked concrete gravity dam by polyurethane resin injection methods. The third case study presents the various procedures used for repairing concrete railway bridge piers in a marine environment which were damaged by severe alkali-aggregate reaction. The final case study describes underwater repair procedures and concrete investigation techniques used in repairing the piers of a highway bridge.

ENGLISH ABSTRACT: Bridges are amongst the most important structures of any highway network. Once the bridge construction is complete and a bridge is put into service, it is subjected to deteriorations. An effective condition assessment, as a component of bridge management system, is therefore necessary to keep bridges in admissible conditions of safety and serviceability. In South Africa, some bridge authorities do not have sufficient funds to carry out bridge inspections at required intervals. In the case where bridge authorities have enough funds, a systematic inspection is performed, covering a number of bridges that are not in need of inspection. Inspection and maintenance for a limited number of bridges randomly chosen may result in an increase of the number of bridges in critical conditions. A bridge inspection prioritisation method that takes into account the need of inspection of bridges is therefore needed for South African highway bridges. This research provides a prioritisation method for concrete bridge inspections by integration of nonprofessional inspectors, imagery inspection and deterioration models. To achieve the research objectives of this study, a literature study has been carried out to understand bridge inspection practice in general and South African practice in particular. The literature helped also to identify previous works on bridge inspection prioritisation, the use of information from informal sources, imagery inspection and involvement of non-professionals in bridge inspection and use of deterioration models in bridge management. A survey has been conducted amongst South African bridge authorities in order to fill the literature gaps. Inventory and inspection data of bridges managed by South African National Roads Agency Limited (SANRAL) was used to develop a deterioration model by considering bridge characteristics such as bridge age, number of spans, and bridge type. Based on the literature review, results of surveys and estimated regression parameters, a bridge inspection prioritisation method has been developed. This method comprises three phases. The first phase is the initial screening that consists of an identification of bridges with critical defects that have not been repaired yet. These bridges, to which are added bridges that have not been inspected in the previous inspection, constitute the first inspection priority category. The second phase is an imagery screening which is an analysis of digital photographs for detection of defects that need urgent assessment by professional inspectors. The analysed photographs are taken by non-professional inspectors and uploaded to the Bridge Management System. The third phase is a grouping of bridges in inspection priority categories as a function of their physical characteristics and deteriorating factors using deterioration modelling. The method has been applied on SANRAL bridges using inspection ratings of 2011-2012. 422 SANRAL bridges have been categorised in the first inspection priority group by considering hydraulic related defects as critical. The third phase allowed to rank 522 possible combinations of bridges based on their characteristics. The developed method would help bridge authorities where inspection budget is limited, to prioritise bridge inspection as a function of needs of inspection.
AFRIKAANSE OPSOMMING: Brûe is ʼn belangrike deel van enige snelweg netwerk. Wanneer brugkonstruksie voltooi is en dit in diens gestel word, is die brug onderhewig aan skade en verval . 'n Doeltreffende toestandsassessering, as 'n komponent van ʼn brug bestuurstelsel, is dus nodig om brûe in ʼn toestand van veiligheid en diensbaarheid te hou. In Suid-Afrika het sommige brugowerhede nie genoeg fondse om bruginspeksies teen vereiste intervalle uit te voer nie. In die geval waar ʼn brugowerhede wel genoeg fondse het, word stelselmatige reekse inspeksies uitgevoer, waar brûe wat nie lukraaknoodwendig op daardie stadium inspeksie nodig het nie, ook soms ingesluit word. Inspeksie en onderhoud vir slegs 'n beperkte aantal brûe wat gekies word kan 'n toename veroorsaak in die aantal brûe wat in ʼn kritiese toestand is. 'n Bruginspeksie prioritiseringmetode wat brûe identifiseer vir inspeksie is dus nodig vir Suid-Afrikaanse brugowerhede. Hierdie navorsing stel 'n metode voor wat bruginspeksies prioritiseer deur gebruik te maak van nieprofessionele inspekteurs, inspeksie van foto’s en brugtoestandsvervalmodelle. Om die navorsings doelwitte van hierdie projek te bereik, is 'n literatuurstudie uitgevoer oor die praktyk van bruginspeksie in die algemeen, en meer spesifiek om die praktyk in Suid-Afrika te verstaan.. 'n Opname is voorts onder Suid-Afrikaanse brugowerhede uitgevoer om gapings in die literatuur aan te vul. Inventaris en inspeksie data van brûe wat bestuur word deur die Nasionale Padagentskap (SANRAL) is daarna gebruik om 'n toestand agteruitgangsmodel te ontwikkel deur die eienskappe soos brug ouderdom, aantal spanne en die tipe brug in ag te neem Gebaseer op die literatuur, resultate van opnames en beraamde regressie parameters is 'n brug inspeksie prioritiseringsmetode ontwikkel. Hierdie metode bestaan uit drie fases. Die eerste fase is die aanvanklike siftingsproses wat bestaan uit die identifisering van brûe met 'n kritiese defek wat nog nie herstel is sedert ʼn vorige inspeksie nie. Hierdie brûe, wat ingesluit word by ander brûe wat nie geïnspekteer was in die vorige inspeksie nie, is die eerste kategorie van inspeksie prioriteit. Die tweede fase is 'n ontleding van digitale foto's vir die opsporing van defekte wat dringende assessering deur professionele inspekteurs nodig het. Die foto's word geneem deur nie-professionele inspekteurs en dit word gelaai op die brug bestuurstelsel. Die derde fase is die groepering van brûe in inspeksie prioriteit kategorieë as 'n funksie van hul fisiese eienskappe en vervalfaktore met die hulp van agteruitgangsmodelle. Die metode is toegepas op die SANRAL brûe met die hulp van inspeksie graderings van 2011-2012. Deur die aanname van hidrouliese defekte as van kritiese belang, is 422 SANRAL brûe in die eerste inspeksie prioriteit gegroepeer. Die derde fase prioritiseer 522 moontlike kombinasies van brûe op grond van hul fisiese eienskappe. Die metode sal brugowerhede waar inspeksie begrotings beperk is, help om bruginspeksies te prioritiseer as 'n funksie van die noodsaaklikheid van inspeksie.

Abstract:
Infrastructure deterioration is an international problem requiring significant attention. One particular manifestation of this deterioration is the occurrence of sub-surface cracking (delaminations) in reinforced concrete bridge decks. Of many techniques available for inspection, air-coupled impact-echo testing, or sounding, is a non-destructive evaluation technique to determine the presence and location of delaminations based upon the acoustic response of a bridge deck when struck by an impactor. In this work, two automated air-coupled impact echo sounding devices were designed and constructed. Each device included fast and repeatable impactors, moving platforms for traveling across a bridge deck, microphones for air-coupled sensing, distance measurement instruments for keeping track of impact locations, and signal processing modules. First, a single-channel automated sounding device was constructed, followed by a multi channel system that was designed and built from the findings of the single-channel apparatus. The multi channel device performed a delamination inspection in the same manner as the single-channel device but could complete an inspection of an entire traffic lane in one pass. Each device was tested on at least one concrete bridge deck and the delamination maps produced by the devices were compared with maps generated from a traditional chain-drag sounding inspection. The comparison between the two inspection approaches yielded high correlations for bridge deck delamination percentages. Testing with the two devices was more than seven and thirty times faster, respectively, than typical manual sounding procedures. This work demonstrates a technological advance in which sounding can be performed in a manner that makes complete bridge deck scanning for delaminations rapid, safe, and practical.

Abstract:
The proposed study explores the feasibility of detecting and quantifying corrosion and delamination (physical separation) at the interface between reinforcing steel bars and concrete using ultrasonic guided waves. The problem of corrosion of the reinforcing steel in structures has increased significantly in recent years. The emergence of this type of concrete deterioration, which was first observed in marine structures and chemical manufacturing plants, coincided with the increased applications of deicing salts (sodium and calcium chlorides) to roads and bridges during winter months in those states where ice and snow are of major concern. Concrete is strengthened by the inclusion of the reinforcement steel such as deformed or corrugated steel bars. Bonding between the two materials plays a vital role in maximizing performance capacity of the structural members. Durability of the structure is of concern when it is exposed to aggressive environments. Corrosion of reinforcing steel has led to premature deterioration of many concrete members before their design life is attained. It is therefore, important to be able to detect and measure the level of corrosion in reinforcing steel or delamination at the interface. The development and implementation of damage detection strategies, and the continuous health assessment of concrete structures then become a matter of utmost importance. The ultimate goal of this research is to develop a nondestructive testing technique to quantify the amount of corrosion in the reinforcing steel. The guided mechanical wave approach has been explored towards the development of such methodology. The use of an embedded ultrasonic network for monitoring corrosion in real structures is feasible due to its simplicity. The ultrasonic waves, specifically cylindrical guided waves can propagate a long distance along the reinforcing steel bars and are found to be sensitive to the interface conditions between steel bars and concrete. Ultrasonic transducers are used to launch and detect cylindrical guided waves along the steel bar.In this dissertation, in-situ corrosion monitoring technique for reinforced concrete is developed based on two methods - 1) variation of signal strength and 2) the time-of-flight (TOF) variations as the corroded member is loaded transversely. This is the first attempt ever to monitor corrosion inside concrete by measuring the change in the time of flight of guided waves along reinforcing bars as the concrete beam is subjected to bending. Advantages of corrosion monitoring by TOF change are discussed in the dissertation.

Abstract:
This work focuses on the development of a methodology for the complete reconstruction of the 3D geometry of a concrete bridge. 3D scanning technology was selected as the most apt to the task as it provides very detailed geometrical informations. A dedicated carriage system for a compact and lightweight laser scanner has been designed and built as a first prototype to be used on laboratory as well as future on-field tests. A first assessment of the design constraints has been carried out, based on the general goal of implementing a system able to be used with existing inspection vehicles with minimal modifications. The specific electronic system for management and control of the carriage system and the management of the associated tracking system has been also designed and realized. Some preliminary tests have been performed at Politecnico di Milano University campus to assess the viability and analyze the performance of the early design choices.

Abstract:
As part of an inspection, bridge inspectors assign condition ratings to the main components of a bridge’s structural system and identify any defects that they observe. Condition ratings are necessarily somewhat subjective, as they are influenced by the experience of the inspectors. In the current work, procedures were developed for making inferences on the reliability of reinforced concrete girders with defects at both the cross section and the girder level. The Bayesian network (BN) tools constructed in this work use simple structural m echanics to model the capacity of girders. By using expert elicitation, defects observed during inspection are correlated with underlying deterioration mechanisms. By linking these deterioration mechanisms with reductions in mechanical properties, inferences on the reliability of a bridge can be made based on visual observation of defects. With more development, this BN tool can be used to compare conditions of bridges relative to one another and aid in the prioritization of repairs. However, an extensive survey of bridges affected by deterioration mechanisms is needed to confidently establish valid relationships between deterioration severity and mechanical properties.

Abstract:
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.

Abstract:
The Indiana Department of Transportation (INDOT) completed a total of 25 high friction surface treatment (HFST) projects across the state in 2018. This research study attempted to investigate the durability and performance of HFST in terms of its HFST-pavement system integrity and surface friction performance. Laboratory tests were conducted to determine the physical and mechanical properties of epoxy-bauxite mortar. Field inspections were carried out to identify site conditions and common early HFST distresses. Cyclic loading test and finite element method (FEM) analysis were performed to evaluate the bonding strength between HFST and existing pavement, in particular chip seal with different pretreatments such as vacuum sweeping, shotblasting, and scarification milling. Both surface friction and texture tests were undertaken periodically (generally once every 6 months) to evaluate the surface friction performance of HFST. Crash records over a 5-year period, i.e., 3 years before installation and 2 years after installation, were examined to determine the safety performance of HFST, crash modification factor (CMF) in particular. It was found that HFST epoxy-bauxite mortar has a coefficient of thermal expansion (CTE) significantly higher than those of hot mix asphalt (HMA) mixtures and Portland cement concrete (PCC), and good cracking resistance. The most common early HFST distresses in Indiana are reflective cracking, surface wrinkling, aggregate loss, and delamination. Vacuum sweeping is the optimal method for pretreating existing pavements, chip seal in particular. Chip seal in good condition is structurally capable of providing a sound base for HFST. On two-lane highway curves, HFST is capable of reducing the total vehicle crash by 30%, injury crash by 50%, and wet weather crash by 44%, and providing a CMF of 0.584 in Indiana. Great variability may arise in the results of friction tests on horizontal curves by the use of locked wheel skid tester (LWST) due both to the nature of vehicle dynamics and to the operation of test vehicle. Texture testing, however, is capable of providing continuous texture measurements that can be used to calculate a texture height parameter, i.e., mean profile depth (MPD), not only for evaluating friction performance but also implementing quality control (QC) and quality assurance (QA) plans for HFST.
