The evaluation on the surface conditions of flexible pavement: case study of Selangor federal road / Nurul Elma Kordi

High quality roads are essential to economic and social growth. However, road damages may inhibit the function of the roads. Therefore, the damages are a concern not only to maintenance authorities, but also to road users. The identification of the main factors contributing to road damages is a prer...

However, road damages may inhibit the function of the roads. Therefore, the damages are a concern not only to maintenance authorities, but also to road users. The identification of the main factors contributing to road damages is a prerequisite to finding the best remedial measures and lasting solutions. Hence, in this study, road damages that occur on the road surface of the Federal Road Route One (FT01) in Selangor were observed and identified. The most common types of damages found at FT01 are fatigue cracks (30%), longitudinal cracks (15%), rutting (15%), patch deteriorations (14%) and edge drop-offs (12%). From the findings, the possible causes of the main damages were determined through careful triangulation, a review of extant literature and by considering the surrounding factors. A case study was also conducted twice at five stations along the FT01 to compare and measure the changes of the road performance. The number of damages and the seriousness-level were found to increase at all stations after six months the first data collection. To avoid bias between party responsible for the road performance and the party that uses the road i.e., road users, questionnaires were randomly distributed to assess the performance of roads and the factors contributing to road damages by criticality index. According to 500 questionnaire responses received, road users establish that overloading of vehicles is the major cause of road damages. The findings were confirmed by a developed model using Structural Equation Modelling (SEM) to: (i) determine the validity of the theories used to identify the factors contributing to road damages, and (ii) validate whether the results obtained from the site observations and the hypothesis were similar. From 12 hypotheses tested, seven were accepted. It is anticipated that the findings are useful as it scientifically identifies the cause of road damages, therefore providing a starting point for improving road designs. 2013 Thesis https://ir.uitm.edu.my/id/eprint/12268/ https://ir.uitm.edu.my/id/eprint/12268/2/12268.pdf text en public mphil masters Universiti Teknologi MARA (UiTM) Malaysia Institute of Transport Endut, Intan Rohani
