Applications
Western Asphalt Products have a variety of applications
Seal Coats are treatments that provide effective pavement maintenance to all structurally sound roadways.
CA-90 is a specially formulated cold pour rubberized crack filler.
Microsurfacing is a thin cold-mix overlay used in the repair and preventative maintenance of roadways.
Cold In Place (CIP) Recycling was a new technology introduced in the early 1990’s in Ontario.
Fog sealing is generally a light application of spray applied slow set emulsion.
Tack Coat is a spray applied emulsion which provides a thin adhesive film of asphalt between existing road pavement and a new surfacing layer.
Dense-graded cold mixed asphalt can be an economical alternative to traditionally hot mixed asphalt, especially in areas where there is a long distance to the nearest hot mix plant.
Specialized Cutback Asphalt and Asphalt Emulsions can be used to create a concrete foundation water proofing.
Applying driveway sealer to an asphalt driveway will improve both aesthetics and lifespan of your asphalt driveway.
