Abstract
A method for repairing cracks in an asphalt or concrete parking lot includes brushing out the cracks to remove loose soil, filling the crack with an adhesive mixture formed of roofing materials, and placing a relatively flat molded cap of a mat saturated with a rubber and a high quality asphalt after the adhesive mixture has cured for a few minutes.
Claims7
A method for making a water impermeable repair for a cracked area in a pavement, such as in a parking lot which experiences vehicular traffic, having an opening extending from a top surface to a depth below the top surface, the method comprising the steps of:
- filling a crack opening in a pavement top surface with an adhesive material to a level corresponding to the plane of the pavement top surface, the adhesive comprising a mixture of a roofing adhesive and a roofing cement and being applied in a pliable condition to produce a relatively smooth surface such that it is continuous with respect to the pavement top surface;
- applying a cap of a cured roofing material over the adhesive material and overlapping the crack opening such that the cap is effective to bear the weight of vehicular traffic prior to the adhesive material fully curing.
