2021 Crack Sealing

1. Routing all cracks to a minimum of 3/4-inch width and 3/4-inch depth to ensure uniform placement of crack filling material, firm walls for product adhesion, and to allow adequate material placement in the joints for an elastic seal. (Any variations to this will be approved by The Road Foreman) 2. Cracks are to be blown clear of loose material and debris using compressed air to ensure consistent and firm adhesion of the product to the existing asphalt pavement. 3. All cracks are to be blown out and dried with a heat torch to eliminate moisture from interfering with product adhesion to the existing asphalt pavement and to aid in the creation of mechanical bond between the product and existing asphalt pavement. 4. Cracks will be filled with product before the sidewalls of the joint cool, and before additional moisture may accumulate in the joint. Cracks shall be over filled to allow for adequate finishing, but not to the extent that product is wasted. 5. Product will be leveled with a squeegee tool immediately after its application. The finished width of product on the road surface is not to exceed three inches, and shall be centered on the crack.
