• 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.
