The objective of the proposed pooled fund study is to create a mechanism to allow for rapidly completing forensic evaluations of LTPP sections before going out of service. Test sections that are no longer active, but which have remained unchanged (i.e., no maintenance or rehabilitation has been applied), may also be considered for forensic evaluation. Possible reasons for carrying out the forensic evaluations include: (1) Determining reasons for poor pavement performance/premature failures; (2) Understanding exceptional pavement performance and/or longevity; (3) Validating pavement performance prediction (predicted vs actual); (4) Collecting data to support development and/or calibration of pavement performance prediction models; and (5) Closing-out/conducting final investigations of experimental test sections. Ultimately, however, the primary reason for carrying out the evaluations will be to determine if the data contained in the LTPP database adequately explains the performance of the test sections and why they performed as they did. |
