Joint and crack faulting measurements are among the key data collected to monitor the performance of concrete pavements in the Long Term Pavement Performance (LTPP) Program. This report documents an assessment of LTPP faulting data undertaken to evaluate their potential use in more in-depth performance analyses. Results of this investigation included: (1) identification, investigation, and correction (as appropriate) of anomalous faulting data; (2) the creation of an LTPP database table with section summary statistics for faulting; and (3) findings regarding the effect of various design features on the occurrence of faulting and the relationship between ride quality and faulting.

This report will be of interest to those concerned with the management and design of portland cement concrete pavements.
