CrackMaster CJA is a hot applied modified asphalt adhesive. It is used as an adhesive and tacking material on longitudinal cold construction joints on asphaltic pavements. The CrackMaster CJA fosters a long lasting seal between two sections of asphaltic pavement. It prolongs pavement service life by sealing that joints from water penetration, which cause base failure and potholes.
CrackMaster provides excellent results in cold weather and through out repeated freeze/thaw cycles. CrackMaster CJA is formulated with select asphaltic resins, synthetic polymeric rubbers, plasticizers, stabilizers, and a blend of organic and inorganic reinforcing fillers.
CrackMaster CJA is applied 1/8 inch thick across the edge of the first paving pass. When the adjacent lane of asphaltic pavement is put into place, the heat from this material and the compaction of the roller cause the CrackMaster CJA to adhere to both lanes. This forms a durable bond between the two overlay passes. this product can also be used as a waterproofing agent on shoulder interfaces, around manhole covers and other utility cuts in asphaltic pavement.
Use material as supplied. Do not blend with other materials. After CrackMaster CJA is melted it should be agitated or recirculated.
