Abstract

A polymer modified cement overlay material is disclosed for a broadly applicable repair, preparation and application method of extending the useful life of road, bridge, parking and aviation pavement. The material is a combination of three Component raw material products that include: a Component A—a latex polymer emulsion; a Component B—a dry blend of Type I Portland cement and a specially sieved washed mason sand; a Component C—a non-skid aggregate; and, water. This composite formula offers different pavement types extraordinary resistance to destructive environmental conditions; it offers enhanced pavement skid resistance and provides a rapid service turn-around, i.e., “return to service”. The method is a combination of three specific and equally significant variables that combined provide for the overall effectiveness of the method. The three variables are as follows; a) extensive surface specific preparation and repair techniques for different pavement types, b) a high-capacity bulk mixing system and placement machine; and, c) a comprehensive, blended polymer modified cement material composition designed for the repair and resurfacing of a wide variety of transportation pavement types.
