Abstract:Asphalt mix durability has always been one of the major concerns of all highway agencies. 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 a systematic balanced mix design (BMD) methodology for designing durable mixes in the laboratory, recommend a performance-related methodology for production quality control and quality assurance (QC/QA) at asphalt plants, and identify innovative practices for placement acceptance in the field. This report summarizes the findings from the research efforts in Year 1.
