  • Abstract:
    The Washington State Department of Transportation (WSDOT) has a long history of designing, constructing, ; and maintaining chip seal or bituminous surface treatment pavements. However, to date WSDOT has not ; developed pavement performance indicators or models to predict chip seal service life, but rather assumes an ; average life of 6 to 8 years. Due to funding constraints and good pavement management practices, WSDOT ; has increased the number of pavement segments that are candidates for receiving chip seal applications. In ; order to improve predictions of chip seal performance and improve their demonstrated cost effectiveness, ; chip seal performance indicators are needed. ; The objectives of this research project are to evaluate different performance indicators for chip seal ; treatments and to develop trigger values for these indicators that will indicate the end of service life and the ; appropriate index values for resurfacing. Under Phase I of this study, a formal literature review and detailed ; survey of transportation agency practices were conducted to identify which pavement distress or combination ; of distresses best characterize the optimal timing for chip seal application. This report summarizes the ; findings of the literature review, agency survey, WSDOT pavement management and performance modeling ; practices, and a recommendation of potential performance models for further evaluation as additional data ; become available.
