Quality Assurance (QA) Aspects of Performance Related Specifications (PRS)

The objective of this research is to develop guidance to integrate the performance predictive capabilities of the PASSFlexTM software and its suite of tools (FlexPAVETM version 2.0, FlexMATTM, and FlexMIXTM) within a statistically sound QA system in a PRS framework. The research shall address: (a)  the use of the cyclic fatigue S_app and SSR allowable traffic for rutting (ATR) index test parameters, index thresholds, and acceptance limits in support of performance engineered mixture design (PEMD) approaches and to facilitate further implementation of the tests and performance predictions, (b)  material selection and mixture design changes that can impact the test results (cyclic fatigue, SSR, and their index parameters) and trends associated with owner agency specified performance thresholds, and (c)  the major elements of a QA system (per TRB E-Circular 235, Glossary of Transportation Construction Quality Assurance Terms ( https://onlinepubs.trb.org/onlinepubs/circulars/ec235.pdf ) and associated buyer/seller and payment risks.
