RES2024-07: Benchmarking Study of TDOT D Mixtures for Balanced Mixed Design
Like many owner agencies, the Tennessee Department of Transportation (TDOT) is interested in ways to facilitate the increased durability of asphalt mixes to make its roadway network more sustainable, longer lasting, and more economical. The balanced mix design (BMD) method proposes to address this by incorporating performance criteria into mix design and acceptance. TDOT has committed to implementing the BMD method to improve asphalt mix performance. This process will require replacing the prescriptive specifications currently in place. TDOT has two proposed tests that could be used theoretically to stand in for the national tests while utilizing Marshall samples. Implementing a new procedure for asphalt mix design is a critical step for the quality of Tennessee asphalt mixtures and requires high-quality data.
