• Setting Appropriate Benefit/Condition Jumps for Pavement Treatments in PMS

    NCDOT Research Project Number: 2016-03

Executive Summary

  • 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 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 was conducted to investigate the magnitudes of pavement performance jumps caused by most common types of treatment utilized by the NCDOT. The data for this research was collected by windshield surveys, and it was divided into treatment. Pre-treatment and post-treatment PCR values were calculated to determine the performance jumps, and after-treatment performance curves were developed. These jumps along with the performance curves can provide better prediction of the pavement condition over its life after a treatment is applied and assist NCDOT engineers in developing effective treatment plans.
