ASTM’s new standard will help road and paving businesses make better use of foundry sand in asphalt mixtures

A new ASTM International Standard has just come out “to help the road and paving industry make better use of foundry sand in asphalt mixtures.”

The new standard (numbered D8140) has been developed by the ASTM International committee on road and paving material (D04).

ASTM International defines foundry sand in the report as “a fine aggregate used to produce moulds or cores for casting. Foundry sand is mostly made of silica sand, lake sand, olivine sand, or zircon sand.”

The guide, says ASTM International, “covers the physical and chemical requirements (grading, shape, density, toxicity) of virgin or recovered foundry sand used in asphalt mixtures. Contractors, foundry sand suppliers, and other relevant purchasers could benefit from the guide.”

The subcommittee that developed the new standard has invited all interested parties to help develop additional standards that use sustainable materials in asphalt mixtures. The next meeting of the committee is June 26-28, 2018 in San Diego, California, USA.

If you would like to purchase a copy of the standard, contact ASTM International customer relations … Tel: 001 877 909 ASTM; Email: sales@astm.org.
