Development of Holistic Methodologies for Improving Asphalt Mix Durability

Asphalt mix durability have always been major concerns of all State DOTs, and they cost taxpayers billions of dollars each year to repair cracking and rutting problems. To have a durable mix, one needs to address three aspects: durable mix design, production, and placement. The objective of this project is to develop holistic methodologies for addressing all three aspects with an ultimate goal to improve asphalt mix durability. As a minimum, this project will develop (1) a systematic methodology for designing durable mixes in the laboratory, (2) a performance-related methodology for production quality control and quality assurance (QC/QA) at asphalt plants, and (3) an innovative methodology for placement acceptance in the field. All the methodologies and findings from this project will be summarized and documented in the final report. To facilitate implementation and transfer the technology coming out this project, the research team will reach out DOTs, contractors, and other stakeholders through publications, presentations at different conferences (such as TRB) and webinars.
