Geogrid Mesh for Reflective Crack Control in Bituminous Concrete Overlays
The study will evaluate three materials for the prevention of reflective cracking in bituminous overlays with rigid bases. These materials are: Petromat, a paving fabric; Bit-U-Tex, a paving fabric with a polyester geogrid heat bonded to a needle-punched nonwoven geotextile and Glasgrid, a bitumen coated fiberglass grid. The Petromat and and Bit-U-Tex were placed on SR 0073 near Gilbertsville. The Glasgrid was placed on SR 0663 near Pennsburg. These paving projects consisted of a 1 1/2 inch depth ID-2 bituminous wearing course overlay. The existing pavements on both projects were a concrete roadway with an existing bituminous overlay. The primary objective of the study will determine if the placement of an AC-20 tack coat and a fabric inter-layer reinforcement of over a rigid substructure prior to a flexible overlay eliminates or reduces the formation of reflective cracks.
