Development of Holistic Methodologies for Improving Asphalt Mix Durability Year 2

项目名称：	Development of Holistic Methodologies for Improving Asphalt Mix Durability Year 2
摘要：	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. A detailed literature review has been completed during the first stage of the Yr 1 research. By the end of Yr 2, 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.
