• Abstract:
  Thickness is currently a pay item for PCC pavements and a quality control item for both PCC and HMA pavements. A change in pavement thickness of 0.5 in. can result in a change of multiple years of service. Current thickness measurements are performed by destructively coring the finished pavement and measuring the thickness of the core. Many times this is performed at the end of the project construction and only five representative samples are collected for each lot. Today, multiple non-destructive pavement evaluation tools are available and the accuracy of such devices has significantly increased in recent years. Nondestructive thickness measurements will allow the Department a more efficient and effective method of maintaining pavement quality without damaging the pavement.
