The study provides recommendations for using the Road Rater Model 400B and the PEDMOD (Pavement Evaluation and Design Model) program for pavement evaluation and design. In order to address seasonal variation in pavement response for pavement evaluation and design, thirty-six test sections were established in eight counties in Washington State. Road Rater deflection data was collected monthly on the test sections for a period of one year. Recommendations are provided for calibrating the Road Rater and performing systemwide and design level deflection testing as well as recommendations for the use of PEDMOD. In addition, recommendations are provided for alternative techniques for pavement evaluation using parameters obtained directly from Road Rater deflection basins.
