Title:

Guidelines for Developing Performance-Related Specifications for Flexible Pavement Preservation Treatments: Microsurfacing

Abstract:

Performance-related specifications (PRS) are quality assurance specifications that describe the desired levels of key materials and construction quality characteristics that have been found to correlate with the long-term performance of the finished product, thus providing the basis for rational acceptance and price adjustments. There are no widely accepted guidelines for PRS of pavement preservation treatments that correlate key engineering properties to treatment quality and long-term performance. This paper presents a concise but comprehensive procedure for developing pavement preservation PRS guidelines and demonstrates the use of the methodology with the help of an example for micro-surfacing treatment. While the relationships between quality characteristics and performance measures can be established using empirical, mechanistic-empirical, and performance-based laboratory and field test properties, the demonstrative example showed an application of the empirical approach. Relationships were further developed between quality measures, service life extensions, and pay adjustment factors. The expected pay curves were developed based on the quality measures and were used to establish acceptable and rejectable quality levels. The pay adjustment factors were evaluated to ensure fair payments for the quality of work produced. Although the demonstrative example presented is unique to micro-surfacing, the same process can be adopted to develop PRS for other preservation treatments.
