PPRC14 SPE 3.32: Support for Superpave Implementation

The objective of this project is to establish annual state-wide round robin (to be taken over by Materials Engineering & Testing Services Independent Assurance (IA) program) for Hamburg Wheel Track Test (HWTT) study to determine precision and bias, and incorporate results in revised specifications. Assess differences between laboratory and plant produced mix, and continued development and implementation of performance related tests. Review appropriateness and applicability of Quality Control/Quality Assurance (QC/QA) testing on Superpave projects and make recommendations for revised specifications if justified. Monitor performance of Superpave projects constructed to date.
