Maintenance Pavement Crack Repair Using Asphalt Roll-Roofing Material

摘要

Asphalt roll roofing was first used for crack repair in the summer in 1977. This report describes the experiences of District 8 (Abilene) with the process. The procedure is described in step-by-step detail, accompanied by photographs. Some results and comments are: (1) roll roofing patches will not bleed through hot mix overlays; (2) pot holes do not develop as quickly as with other methods; (3) no special skills are needed by the maintenance crew to place the patches, and more cracks can be patched by this method than can be poured (1050 square yards/day versus 350 square yards/day of premix patches); (4) the cost is less.
