Development of Holistic Methodologies for Improving Asphalt Mix Durability (Yr 1)

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. 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.
