Crack Leveling

I. DESCRIPTION This work consists of repairing recessed joints in asphalt concrete pavement with a specified sealant material without milling or routing. II. MATERIALS Asphalt repair mastic will be composed of quality-selected asphalt and/or resins, select aggregates with structural integrity, synthetic rubber polymers, antioxidants, naturally occurring and man-made reinforcing material, and other modifiers. Asphalt repair mastic will be Deery Level and Go Repair Mastic, Crafco Mastic One, Maxwell GAP MOD 201, or SAMIscreed meeting the appropriate specifications below or an approved equal. A.
