Escondido Asphalt Sand and Dust
We at Escondido Asphalt are pleased to anounce our participation with resurf.org, in the research and development of introducing rigid polyurathane foam dust(pulverized surfboards) to asphalt and cementitious mixes.So far, our sample mixes have been successful. We have found that mixing the pulverized material to molton asphalt before mixing it to the heated aggregate,not only renders the toxic material inert, but we have found the impregnated matrial is not thermally conductive, and volumizes the mix, making the mix more cost effective.The concept of " paving roads with surfboards " is exciting and realistic . As for lightweight concrete mixes,it's alraedy a prooven concept in highrise flooring substraights , lightweight roofing tiles and various other construction applications.
