Update State Study No. 170 Deliverables with New PCC Test Data Revised final report for SS No. 170, “AASHTO 2002 Pavement Design Guide-Phase II” – Volume 1

The objective of this research study was to develop performance characteristics of flexible and rigid pavements in Mississippi and to use these characteristics in the implementation of the Mechanistic-Empirical Pavement Design procedure that was developed under NCHRP Project 1-37A. Reliable transfer functions and models will enable the Mississippi Department of Transportation (MDOT) to more accurately quantify the pavement service and performance life for managing their roadway network. Calibration coefficients for all transfer functions in the Pavement ME Design software package were determined for both flexible and rigid pavements. Both Long Term Pavement Performance (LTPP) and non-LTPP test sections were used to estimate, for interim use, the local calibration coefficients. The inputs for the non-LTPP calibration sites were based on as-built records and construction files. Thus, these calibration coefficients are considered preliminary until the field investigations have been completed for the non-LTPP sites.
