Framework for Design, Production, and Placement of Balanced Asphalt Mixtures

Balanced mix design (BMD) of asphalt mixtures is an approach that addresses different modes of distress through mechanical tests on conditioned specimens that consider mix aging, traffic, climate, and location within the pavement structure. These tests are intended to assess how well the mixture resists common forms of distress. However, BMD lacks consideration of the issues associated with asphalt mixtures produced at production facilities and the effects of placement. Also, there is no widely accepted framework for identifying the combinations of performance tests and procedures for the different applications. There is a need to enhance the BMD process and develop a framework that addresses design, production, and placement of balanced asphalt mixtures. Such a framework should help highway agencies and other organizations evaluate and select balanced asphalt mixtures for use in pavement structure. The objective of this research is to develop a framework for design, production, and placement of balanced asphalt mixtures. The framework shall focus on enhancing the BMD design process, address the different applications of asphalt mixtures, and delineate the set of performance tests and procedures required for each application. Also, the framework shall address the different applications of asphalt mixtures and delineate the set of performance tests and procedures required for each application.
