The recycling of spent sandblasting grit, commonly referred to as spent abrasive blast material ABM, into asphaltic concrete has been investigated by the U.S. Navy as an alternative to disposing the spent ABM in a landfill. This technology transfer report discusses issues related to the technical feasibility and regulatory acceptability of this concept and relates lessons learned from two U.S. Navy ABM-to-asphalt recycling projects, one at Construction Battalion Center CBC, Port Hueneme in southern California, and the other at Naval Station Treasure Island, Hunters Point Annex HPA in northern California. The critical issues include sampling and chemical characterization of the spent ABM, asphalt mix design criteria, the development of a work plan for the recycling project, regulatory compliance considerations, and cost.The advantages and disadvantages of recycling spent ABM into asphalt are discussed. The merits of recycling versus some other option should be evaluated on a case-by-case basis.
