Micro-Surfacing is a polymer modified asphalt emulsion based, dense graded, cold mixed, quick setting, bituminous resurfacing material. It is designed to be applied in a semi-liquid condition with a specialized mixing and paving machine. By design, it chemically changes from a semi-liquid material to a dense cold mix material that is able to carry normal traffic within one hour after application. Micro-surfacing is applied in order to preserve and protect the underlying pavement structure and provide a new driving surface.
