Norjohn Contracting 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.
