Abstract:
A crack repair method for pavement and recreational surfaces includes a slip layer formed over a filled crack which prevents the adhesion of at least one stretchable sheet to the crack while wider outer edges of the sheet are bonded to the top pavement surface. Optionally a second wider stretchable sheet is adhesively applied over the first sheet. Outer edges of the uppermost stretchable sheet are optionally covered by fiberglass fabric strips. In one aspect, the slip layer is formed of one or more tape strips adhesively joined on one side to the filled crack and to the top surface of the pavement surrounding the filled crack. In another aspect, a slip layer having a non-adherable, exposed surface is carried on the bottom surface of the first sheet, with the first sheet adhered at outer side edges extending outward beyond the side edges of the slip layer to the top surface of pavement surrounding the filled crack by an adhesive layer applied over the top surface of the crack and for a distance beyond the side edges of the crack. The strips and the sheets of stretchable material progressively increase in width and length in the stack buildup.
