NCHRP Project 9-22 developed a performance-related specification for hot mix asphalt (HMA) construction named the Quality Related Specification Software (QRSS) using pre-solved solutions of the MEPDG for permanent deformation, fatigue cracking, and thermal cracking. The QRSS is stand-alone software for the Microsoft Windows operating system; it integrates prediction of distress and IRI with all necessary data input and output capabilities needed to compare the performance and service life of as-designed and as-built HMA pavements and calculate pay factors from service life differences.
OBJECTIVES
The objectives of this research were to (1) evaluate the QRSS Version 1.0 with quality assurance (QA) data obtained from state DOTs and (2) compare QRSS results obtained with various levels and types of measured mix volumetric and performance data.
