RP 6297

Joint Sealants

Category:

RP 6297 is a hot applied polymer modified asphaltic binder. This pre-packaged binder is one component of the RP 6297 plug joint system.
• High Workability for Less Handling
• Superior Bond to Existing Pavement
• Flexible & Highly Durable

RP 6297 can be used in flooding or fill & compact methods when installing asphaltic plug joint systems. Heating the binder within the installation temperature range is critical to achieve the typical binder properties and recommended coating thickness.

Use an agitated, oil-jacketed unit that has separate temperature gauges for both the sealant and the heat transfer fluid. Take the plastic bag of binder and load into the kettle one at a time. Melt only enough material for the day’s activities. Once melted, additional material can be added as needed. Material can be safely reheated within the sealants service life. NOTE: Prolonged heating of the sealant above the maximum safe heating temperature may cause it to gel in the kettle.

The service life when heated to application temperature is approximately 12 hours. Adding fresh material to the melter as sealant 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.
