Identifying the problematic areas with structural deficiencies of pavements using non-destructive tests (NDT)

ABSTRACT

The damage that frequently occurs on pavements will affect the safety and comfort of road users. Road surface conditions’ assessment is a way to determine the type of program evaluation that needs to be done. The purpose of this research was to assess the structural conditions of pavements with non-destructive tests, such as pavement condition index , falling weight deflectometer, total pavements acceptance device and ground penetrating radar. The descriptive study was conducted to compare the road conditions’ assessment data that resulted from different methods for analysing the results of the road evaluation. This study was carried out at Victoria Regional Airport and focused on the analysis of the runway 13R that had two main sections.
