“…The results of the simulation analyses ( Figure 19) show higher DLC values, increasing vehicle speed in analogy with literature studies [34,37]. The DLC calculation was performed considering just a limited segment having a total length of 100 m: 50 m before and 50 m after the BEJ1.…”

Bridge Expansion Joint in Road Transition Curve: Effects Assessment on Heavy Vehicles

et al. 2017

Properly-designed road surfaces provide a durable surface on which traffic can pass smoothly and safely. In fact, the main causes that determine the structural decay of the pavement and its parts are the traffic loads. These repeated actions can create undesirable unevennesses on the road surface, which induce vertical accelerations on vehicles, up to hindering contact between pavement and tire, with dangerous consequences on traffic safety. The dynamic actions transmitted by the vehicles depend on these irregularities: often, a bridge expansion joint (BEJ), introducing a necessary discontinuity between different materials, determines from the beginning a geometric irregularity in the running surface. Besides, some structural conditions could emphasize the problem (e.g., local cracking due to the settlement of the subgrade near the abutment or the discontinuity of stiffness due to the presence of different materials). When the BEJ is located in a transition curve, an inevitable vertical irregularity between road and joint can reach values of some centimeters, with serious consequences for the road safety. This paper deals with the analysis of a case study of a BEJ. Several test surveys were performed in order to fully characterize the effects on both vehicles and pavement. The three-dimensional representation of the pavement surface and the acceleration measurements on a heavy test vehicle were performed to analyze the joint behavior under traffic. Finally, a finite element model was implemented to evaluate the stress contribution on vehicle components induced by the vertical irregularities.

“…On the basis of the tool adopted, specific input data are necessary, which are characterised by different accuracy and precision levels, and are acquired by different techniques, which contributes to determining the global performance and cost of a PMS. Several authors [21,26,27] focused their researches on the analysis of the relation between accidents and pavement conditions, expressed in term of common indices: according to the literature review Pavement Condition Index (PCI), International Roughness Index (IRI), Ruth Depth (RD), and Pavement Serviceability Index (PSI) are the most used ones in representing a global or peculiar aspect of the road pavement. Table 1 summarises the above-mentioned indices.…”

“…The Present Serviceability Index (PSI) is a parameter that is used to describe the functional condition of pavement with respect to ride quality: it provides a valuation of the ability of the road to serve traffic: it takes into account several road characteristics, such as slope variance, rut depth, cracking, and patching surface, as reported in [27]. The PSI is used to provide a comprehensive evaluation of pavement conditions, for both safety and comfort aspects: the complexity makes several input data necessary to the calculation.…”

Pavement Distress Detection Methods: A Review

The road pavement conditions affect safety and comfort, traffic and travel times, vehicles operating cost, and emission levels. In order to optimize the road pavement management and guarantee satisfactory mobility conditions for all road users, the Pavement Management System (PMS) is an effective tool for the road manager. An effective PMS requires the availability of pavement distress data, the possibility of data maintenance and updating, in order to evaluate the best maintenance program. In the last decade, many researches have been focused on pavement distress detection, using a huge variety of technological solutions for both data collection and information extraction and qualification. This paper presents a literature review of data collection systems and processing approach aimed at the pavement condition evaluation. Both commercial solutions and research approaches have been included. The main goal is to draw a framework of the actual existing solutions, considering them from a different point of view in order to identify the most suitable for further research and technical improvement, while also considering the automated and semi-automated emerging technologies. An important attempt is to evaluate the aptness of the data collection and extraction to the type of distress, considering the distress detection, classification, and quantification phases of the procedure.

“…It was seen as the ultimate point reached in the PMS engineering on the evaluation of vibrations is the generation of the simulation models and the real-time test mechanisms. In other words, when all the PMS studies are evaluated, it can clearly be seen that, pavement serviceability can be determined even before the road is constructed due to the deteriorations in the pavement, which will be produced following its design by using the latest technology, that will occur in time and the impact of these deteriorations on the drivers [18,[21][22][23][24][25][26].…”

The pavement condition index (PCI) provides an indication of the current performance of a pavement, and takes the form of a numerical rating, with 0 being the worst possible condition and 100 being the best. The PCI is a subjective method for the evaluation of pavements that is based on inspection and observation. Knowledgeable and experienced pavement engineers make a systematic evaluation of road conditions by driving on the road network, and enter their observations into a database for further evaluation. This case study made use of PAVER software to obtain PCI values for twenty road sections that experience different volumes of traffic in the Samsun region. First, the condition of each road section was evaluated using the PAVER procedure, after which, vertical vibration data was recorded for the same road sections using accelerometers mounted at three different locations within the car: the driver's seat, over the central axis and the front passenger seat. The car was driven at a constant 40 km/h during the tests. In the final stage, the relationship between the vibration data and the PCI values obtained during the site study was examined, and PCI prediction models were created for use in the assessment of urban roads.
