THE USE AND ABUSE OF SEAL COATS

IT IS SUGGESTED THAT SEALING BE DONE ONLY IN WARM WEATHER AND AT THE FIRST SIGN OF DISTRESS. IN ADDITION, SEALING IS NOT TO BE USED TO CORRECT CRACKS DUE TO BASE FAILURE OR TO CORRECT PUSHING OR SHOVING. HANSON'S METHOD IS GIVEN FOR DETERMINING THE QUANTITY OF AGGREGATE AND ASPHALT. THE DESIRABLE PROPERTIES NEEDED BY THE ASPHALT FOR SEAL COAT WORK ALSO ARE ANALYZED INCLUDING FLOW CHARACTERISTICS, VISCOSITY, GOOD WEATHERING PROPERTIES, ADHESION, AND CORRECT RESIDUAL ASPHALT CONTENT. SUGGESTIONS ARE GIVEN ON THE CORRECT CONSTRUCTION OF SEAL COATS. THE MOST PERTINENT SUGGESTIONS ARE: ALL SEAL COATS SHOULD BE ROLLED WITH A ROLLER, THE AGGREGATES SHOULD BE APPLIED AS SOON AS POSSIBLE ON THE ASPHALT, AND THE TRAFFIC SHOULD BE KEPT OFF UNTIL THE BINDER SETS UP. /AUTHOR/
