RP PAVE PATCH BLACK A is a hot applied, single package, ready to melt patching compound used to repair asphalt and concrete pavements. It is specially formulated with a highly modified asphalt binder and aggregates that conform to or exceed the physical requirements of aggregates used in hot mix paving. RP PAVE PATCH BLACK A, when properly applied, will provide many years of service to distressed pavements that need repair to reduce further deterioration. It is typically used in wide pavement cracks, joint separations, spalled concrete joints, utility cuts, and ride leveling.
- Highly workable for less handling
- Superior bond to existing pavement
- Load bearing and impact resistant

Use a jacketed melter with a full sweep horizontal agitator that can maintain a pour temperature between 350 °F and 400 °F. Not subject to pumping with typical pumps used for sealant due to high aggregate loading.
To facilitate proper adhesion, the joint or crack should be dry and clear of any dirt, dust, or other contaminates. Substrate and ambient temperatures must be 40 °F or above. Proper sizing of the joint will cause the maximum extension/compression to not exceed 50% of the width. Joints or random cracks of ¼” or less are difficult to properly clean prior to applying the sealant.
The approximate coverage rate of RP PAVE PATCH BLACK A is 110 lbs/ft³. To facilitate proper adhesion, the pavement should be clean and dry and clear of any dirt, dust, or other contaminates. It is recommended that the repair area edges be saw cut or milled to ensure bonding to sound pavement. Pavement temperatures at time of repair should be 40 °F minimum. After repair area is prepared the entire area is to be conditioned with Right Prime. A light application may be applied by spraying or brushing avoiding making puddles and allowed to dry before applying RP PAVE PATCH BLACK A. The material is then dispensed directly into the repair area in lifts if necessary to help facilitate cooling and smoothed to surrounding surfaces with a hot iron.
The service life when heated to application temperature is approximately 12 hours. Adding fresh material to the melter as mastic is being used will extend the service life. Product shall be agitated during installation. Any material that has exceeded the service life should be removed from the melter and discarded.
