HOT-POURED SEALANTS

HOT-POURED SEALANTS ARE EITHER STRAIGHT ASPHALT CEMENTS OR ASPHALTS THAT HAVE BEEN MODIFIED WITH FILLERS OR RUBBER OR BOTH. THEY ARE THE LOWEST IN COST AND THE MOST WIDELY USED SEALING MATERIALS AVAILABLE TODAY. SPECIFICATIONS FOR HOT-POURED SEALANTS ARE BEING WRITTEN ON THE BASIS OF LABORATORY TESTS THAT OFTEN DO NOT CORRELATE WITH ACTUAL FIELD PERFORMANCE. SEALANT PERFORMANCE DEPENDS ON THE TYPE, QUALITY, AND QUANTITY OF THE MATERIALS USED. IT IS SUGGESTED THAT MATERIALS REQUIREMENTS BE INCLUDED IN SEALANT SPECIFICATIONS. VARIOUS TYPES OF RUBBER USED, AND MANUFACTURING COSTS INVOLVED, IN THE PRODUCTION OF RUBBERIZED ASPHALT SEALANTS ARE DISCUSSED. INSTALLATION PROCEDURES AND PROBLEMS AFFECTING SEALANT SERVICE LIFE ARE GIVEN. COST COMPARISONS ARE MADE BETWEEN HOT-POURED SEALANTS AND OTHER JOINT-SEALING MATERIALS. RESEARCH IS SUGGESTED THAT SHOULD RESULT IN A BETTER UNDERSTANDING AND IMPROVED QUALITY OF HOT-POURED SEALANTS. /AUTHOR/
