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…

Many state departments of transportation are collecting traffic data in real time and using it to manage traffic or provide travel information, as part of intelligent transportation systems. Some agencies save and archive this data after its initial real-time use and make it available to other data users, who often know little about how the data was collected or even what is contained in the data…

ASTM International, one of the largest voluntary standards development organizations in the world, today announced the formation of a new committee to develop standards for the evaluation of materials and products relative to the restriction of certain hazardous substances. Committee F40 on Declarable Substances in Materials will address issues that could have a devastating economic impact on…, Beginning the Standardization Process, On Oct. 15, 2004, representatives from the appliance, electric tool, electronic, laboratory, instrument manufacturing, and supplier sectors affected by RoHS legislation attended a planning meeting at ASTM International Headquarters. They agreed to hold an organizational meeting to discuss the creation of a new standardization activity on declarable substances. The organizational meeting occurred…, Participation Is Open, The development of standards within Committee F40 represents a chance to help the environment while constraining unnecessary compliance costs that may damage many sectors of the world economy. If you are part of the business sectors mentioned above, participation in F40 is in your economic interest. The next meeting of Committee F40 will take place May 26-27, 2005, at ASTM International…
