Forensic Investigation

Pavement failures occur from the development of cracks and ruts and can take place in the form of a seal or asphalt failure or failure to the supporting pavement basecourse, subbase and subgrade layers.
As part of its investigative work in order to provide an optimum solution, STATS will conduct detailed visual inspection of the pavement, followed by non-destructive tests such as the Falling Weight Deflectometer Survey, Ground Penetrating Radar Survey, together with the use of localised intrusive tests such as the Instrumented DCP, ASTM DCP, Light Drop Weight tests, to further understand the causes of the observed defects. This will be followed by localised intrusive test pitting, coring to examine the insitu layers and collecting bulk samples for further laboratory tests. Based on the results, STATS will offer to carry out an independent pavement design review and provide rehabilitation measures and implement a maintenance strategy for the affected pavement.
