Last week's signing of an Agreement on Standards between ASTM International and the American Association of State Highway and Transportation Officials (AASHTO) is good news for the ready mix industry. ASTM International President James A. Thomas and AASHTO Executive Director John Horsley signed the agreement at AASHTO headquarters in Washington, DC. The document is an outgrowth of the ongoing relationship between the two groups and serves as a future basis for continued mutual cooperation on the development and publication of standards related to highway construction.
