The use of mixture performance tests is becoming more widespread for mixture design and QC/QA processes. There are guidelines for conducting these tests, but they do not all provide uniform or comprehensive direction for fabricating test specimens. This webinar will provide participants with an understanding of variables in specimen fabrication that could impact performance test results, procedures and practices that have been developed for improved consistency in fabricating performance test specimens, and common challenges and knowledge gaps.
This webinar draws on research from the National Cooperative Highway Research Program (NCHRP) Synthesis Report 552: Practices for Fabricating Asphalt Specimens for Performance Testing in Laboratories.
* Identify variables in fabrication processes of asphalt performance test specimens
* Learn potential impacts on performance test results and practices for consistent specimen fabrication
* Understand knowledge gaps and future research needs in improving specimen fabrication practices for asphalt lab performance tests
