Surface Treatment

Norjohn Contracting and Paving is equipped with state of the art distributors and chip spreaders to meet your surface treatment requirements. Our operations encompass the Province of Ontario. Surface Treatment is a low cost maintenance technique often used as the final surface on roadways and parking lots. This method produces an all-weather surface, renews weathered pavements, improves skid resistance and seals granular surfaced roads.

Single Surface Treatment
A Single Surface Treatment consists of four basic steps. First the existing pavement is swept clean to ensure proper adhesive, followed by a conventional asphalt distributor that sprays a uniform application of emulsion onto the surface. A chip-spreader follows the distributor and applies a uniform layer of clean aggregate. The fourth and final stage of the process is to roll the area to set the clean aggregate into the emulsion.

Double Surface Treatment
A Double Surface Treatment consists of two alternate uniform applications of asphalt, emulsion and cover aggregate. Both Single and Double Surface Treatments can extend a road's life for 6 to 10 years with no maintenance.
