PROMISING REPLACEMENTS FOR CONVENTIONAL AGGREGATES FOR HIGHWAY USE

THIS REPORT REVIEWS THE CURRENT STATUS OF AVAILABILITY OF ACCEPTABLE AGGREGATES FOR HIGHWAY CONSTRUCTION, AND NOTES AREAS WHERE SHORTAGES NOW EXIST OR CAN BE EXPECTED TO OCCUR IN THE FORSEEABLE FUTURE. VARIOUS POSSIBLE WAYS FOR ALLEVIATING SHORTAGES, INCLUDING TECHNIQUES FOR BENEFITING EXISTING LOW-QUALITY NATURAL AGGREGATES, AND PROCESSES FOR MANUFACTURING SYNTHETIC AGGREGATES FROM VARIOUS SOURCE MATERIALS, INCLUDING WASTE MATERIALS, ARE SUGGESTED. THE RESEARCH EFFORT WAS CONFINED TO A WORKSHOP-CONFERENCE AND A SUPPLEMENTAL LITERATURE STUDY THAT PROVIDED A GOOD OVERVIEW OF THE AGGREGATE SITUATION, BOTH PRESENT AND FUTURE. THE TECHNOLOGIES FOR BENEFICIATING EXISTING AGGREGATES AND FOR MANUFACTURING SYNTHETIC AGGREGATES REMAIN TO BE DEVELOPED BY OTHERS. FOURTEEN PRINCIPAL AREAS FOR RESEARCH WERE IDENTIFIED IN THE STUDY. THE CONTENTS OF THIS REPORT WILL BE OF PARTICULAR INTEREST TO HIGHWAY MATERIALS ENGINEERS AND HIGHWAY RESEARCH AND DEVELOPMENT ENGINEERS, AGGREGATE PRODUCERS, AND OTHERS WHO ARE INTERESTED IN THE DEVELOPMENT OF NATURAL RESOURCES OR WHO ARE INVOLVED IN WASTE MANAGEMENT AND ARE SEEKING ECONOMICAL MEANS FOR THE DISPOSAL OF WASTE PRODUCTS.
