报告摘要:Forensic investigations of pavement failures are critical, as the information gained can be used to identify the underlying causes of the problem, develop an optimal rehabilitation strategy, and to resolve construction disputes.  Knowledge of the presence and extent of subsurface defects is critical to prevent the problem from reoccurring.  The use of nondestructive testing techniques (NDT) such as GPR, LiDAR, and Total Pavement Acceptance Device (TPAD) are well established within the Texas Department of Transportation (TxDOT).  For rehabilitation projects, it is critical to identify weak spots and then to apply localized repairs before placing a structural overlay. A NDT survey in coordination with augering, coring, and DCP testing can rapidly determine the extent and cause of the problem.  This testing provides a comprehensive evaluation of subsurface conditions about the entire project.  These techniques have been used to resolve hundreds of problematic projects and are applicable to a wide range of forensic studies of premature failures and pavement rehabilitation studies. Numerous case studies and lessons learned will be presented.
