A NEW APPROACH TO SUBSEALING
THIS PAPER DESCRIBES THE DEVELOPMENT OF AN ASPHALT EMULSION FOR SUBSEALING CONCRETE PAVEMENT. THE ASPHALT EMULSION CONTAINS A MICRO-AGGREGATE OR FILLER THAT MAKES THE RESIDUE FROM THE BROKEN EMULSION A MASTIC. THIS MASTIC IS TOO STIFF TO BE SQUEEZED THROUGH THE JOINTS OR CRACKS IN THE CONCRETE. THE ASPHALT EMULSION SUBSEALER IS APPLIED COLD WITH STANDARD BITUMINOUS EQUIPMENT AND IS SUCCESSFULLY USED IN DAMP OR WET AREAS. THIS MATERIAL DOES NOT TRACK ON THE PAVEMENT IF ANY SPILLAGE IS ALLOWED TO DRY BEFORE TRAFFIC HITS IT. SEVERAL YEARS OF EXPERIENCE IN SUBSEALING WITH THIS ASPHALT EMULSION IN NORTH CAROLINA INDICATE THAT IT IS A SAFE, ECONOMICAL, EFFECTIVE SUBSEALER FOR CONCRETE PAVEMENT. /AUTHOR/
