Abstract
The present invention defines and illustrates a method for extending the life of road, bridge, parking and aviation pavement. The material is combination of: A—a latex polymer emulsion; B—a dry blend to Type 1 Portland cement and specially sieved washed mason sand; C—a special non-skid aggregate; and water. This composite formula offers pavement resistance to destructive environmental conditions; enhanced pavement skid resistance, and provides a rapid service turn-around. The method is a combination of three variables: a) extensive surface preparation and repair techniques for different pavement types, b) high-capacity bulk mixing system and placement machine; and c) a blended polymer modified cement material composition for repair and resurfacing of a variety of transportation pavement types.
