50 lb. box with two 25 lb. cubes per box.
Use the following chart as a guideline for estimating material requirements (based upon pounds of material needed for 100 feet of cracks):
|Crack Width||Depth||lbs. / 100 ft|
NOTE: The above coverage rates are only a guideline. Actual material usage may vary due to width of application and thickness of material above pavement surfaces.
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.
Apply heated CrackMaster CJA using either a pump and wand system or a pour pot. For best results the sealant depth to width ratio should not exceed 2 to 1 (i.e. 2-inches deep to 1-inch wide). The cooled sealant height should not exceed 1/8″ above surrounding pavement. Using a sealing shoe or squeegee, band the material 2 to 3 inches wide over the crack.
Protective apparel is recommended with application of CrackMaster CJA. The extremely hot material will cause severe burns on contact with skin. OSHA Safety Regulations require workers to wear the following types of safety attire (see current OSHA/Safety Regulations for additional information): Hard hat with face shield; long sleeved shirt buttoned at the wrist; heat resistant gloves; long, cuffless pants; and safety toed work boots. Make certain all area around melter is clear of all debris and flammable materials. Avoid breathing vapors. Use with adequate ventilation.
Wash tools in water before material dries.
