Short-term Comparison of Frictional Properties of Superpave and Balance Mix Design Hot Mix Asphalt Mixes
… 1 only considered volumetric properties and not mixture performance tests. Therefore, development in the asphalt community has addressed some of the issues with the Superpave mix design, e.g., cracking and raveling, with the Balance Mix Design (BMD) approaches. The Balance Mix Design incorporates …
