D8239 ASTM Specification will help grade performance of Road Pavement Materials

D8239 ASTM Specification will help grade performance of Road Pavement Materials

A new international standard announced by the American Society for Testing and Materials (ASTM) will help grade the performance of road pavement materials.

The new specification D8239 will provide performance standards for liquid asphalt used in road construction using multiple stress creep and recovery testing.

These classifications will rate asphalt for resistance to high-temperature rutting, low-temperature cracking and durability, over a range of temperatures and traffic loads.

ASTM International member Bob Kluttz of Kraton Polymers, said: “This D8239 standard will be used by pavement materials and design engineers to ensure pavements will last as long as intended.”

Mr. Kluttz added that engineers can specify the performance grades for their projects, which asphalt producers can then use the ASTM D8239 standard tests on their products.

Contractors, agencies and third-party test laboratories can also use the ASTM standard to conduct quality assurance asphalt testing.

The new ASTM specification has an equivalent standard M332 published by the American Association of State Highway and Transportation Officials.

According to Kluttz the ASTM and AASHTO with the co-operation of the US Federal Highway Administration expert task groups all co-operate to improve their standards and keep them in sync.

The D8239 standard was published by the ASTM International committee on road and paving materials D04.
