This research was conducted to determine pavement performance jumps after treatment, which are defined as the difference between pre-treatment and post-treatment Pavement Condition Rating (PCR) values. the North Carolina Department of Transportation (NCDOT) resets the PCR of roadway sections to its highest value of 100 after a treatment is applied. However, the condition of a pavement after treatment depends on the treatment applied, indicating that the PCR after treatment can be less than 100. This research dealt with this issue by determining PCR values after treatment. The data for this research was collected using windshield surveys, and it was divided into treatment families which were based on the most common treatments applied by the NCDOT on their asphalt and concrete pavements. Pre-treatment and post-treatment values were calculated to determine the performance jumps, and after-treatment performance curves were developed. These jumps along with the performance curves can enable better prediction of the pavement condition over its life after a treatment is applied, and eventually allow agencies to make informed pavement management decisions.
