Sensitivity Evaluation of Balanced Mix Design Performance Tests

Balanced mix design (BMD) of asphalt mixtures is an approach that addresses different modes of distress through performance tests on conditioned specimens that consider mix aging, traffic, climate, and location within the pavement structure. Results of these performance tests are expected to reflect their sensitivity to the variations in mixture constituents and methods of test (herein called mix and test variables). However, limited information is currently available to demonstrate sensitivity of the results of BMD performance tests to these variations.  Research is needed to acquire the necessary information and determine the sensitivity of test results to the variations in mix and test variables. This information should improve applicability of the BMD process and help highway agencies and other organizations with its implementation. The objective of the research is to determine the sensitivity of the results of BMD performance tests to the variations in mix and test variables.
