Pagination or Media Count:
Asphalt concrete overlays of a jointed or cracked portland cement concrete PCC pavement can develop reflective cracking because of either horizontal or vertical movement of the PCC. One method that can be used to reduce the reflective cracking is cracking and seating of the PCC prior to placement of the asphalt concrete overlay. The PCC is cracked into approximately 18-in. pieces, after which a heavy pneumatic-tired roller is used to seat the pieces of concrete to prevent rocking or movement under traffic. This report provides guidance for the application of the cracking and seating method for reducing reflective cracking. Keywords Maintenance, Repair, Concrete coatings.
