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…

A new ASTM International standard provides information and criteria for estimating the thickness of oil on water using only visual clues. The standard, F 2534 , Guide for Visually Estimating Oil Spill Thickness on Water, was developed by Subcommittee F20.16 on Surveillance and Tracking to provide a consistent means of visual oil spill thickness detection. Subcommittee F20.16 is under the…

The ongoing need to deal with oil in stranded ships, especially those in remote areas, is the impetus behind a proposed new standard being developed by ASTM International Committee F20 on Hazardous Substances and Oil Spill Response. One possible response to such a crisis, burning the oil on the ship before it can damage the environment, is the subject of the proposed standard, F 2533, Guide for…
