Current methods for determining bulk specific gravity of aggregate are often time-consuming and not ideal for quality control checks during construction. However, a new ASTM International standard provides a fast method for determining the consistency of aggregate properties that are used in asphalt and concrete mixtures. Committee D04 on Road and Paving Materials has approved ASTM D7370…

Two new standards have recently been approved by ASTM International Committee D04 on Road and Paving Materials. The standards, both of which are under the jurisdiction of Subcommittee D04.26 on Fundamental/Mechanistic Tests, are D 6931 , Test Method for Indirect Tensile (IDT) Strength of Bituminous Mixtures, and D 7312 , Test Method for Determining the Permanent Shear Strain and Complex Shear…, ASTM D 6931, Test Method for Indirect Tensile (IDT) Strength of Bituminous Mixtures, The withdrawal of D 4123 , Test Method for Indirect Tension Test for Resilient Modulus of Bituminous Mixtures, led to the development of D 6931 , since D 4123 contained a description of an indirect tensile strength test that was referred to in several other standards. It was decided to develop this test into a completely separate standard, D 6931, to stand on its own merit as a method that…, ASTM D 7312, Test Method for Determining the Permanent Shear Strain and Complex Shear Modulus of Asphalt Mixtures Using the Superpave Shear Tester (SST), According to Rebecca McDaniel, technical director, North Central Superpave Center, and leader of the D 7312 task group, Superpave is a system for designing asphalt mixtures to ensure that the right asphalt binder and aggregate structure is used for the traffic and climate where it will be placed on the road. To facilitate the implementation of Superpave, the Federal Highway Administration…
