Synthesis of Information Related to Highway Problems. Topic 46-03. Performance Specifications for Asphalt Mixtures

Asphalt mixtures are typically designed within a given gradation band to meet a set of volumetric properties at a given laboratory compaction effort. This project will document the state-of-the-practice in performance specifications for asphalt mixtures and their use with traditional volumetric properties. Performance specifications can be performance related and/or performance based. Asphalt mixtures include both hot mix asphalt and warm mix asphalt. Volumetric properties may not provide optimum performance for mixtures that include recycled materials and/or certain types of modifiers. Some agencies have investigated performance specifications for asphalt mixtures. These specifications typically include tests for rutting and cracking. In addition, certain areas may require performance tests to address specific requirements, such as studded tire wear and moisture susceptibility tests. The scope of this synthesis study will focus on performance tests used in conjunction with volumetric properties for mixtures. Performance tests are intended to extend service life by guiding material selection (i.e. asphalt binder and aggregate) and proportions (i.e. asphalt content and gradations). Results will benefit government agencies, researchers, and the road-building industry in providing guidance on making better use of recycled materials while also providing better performing and more cost-effective asphalt mixtures for specific applications. .
