A polymer modified cement overlay material is disclosed for repair of a variety of pavement surfaces. The material is a combination of three Components: A-a latex polymer emulsion; B-a dry blend of Type I Portland cement and a sieved washed mason sand; and, C-a non-skid aggregate, and water. This material offers excellent resistance to destructive environmental conditions; enhanced pavement skid resistance; and, provides a rapid service turn-around, i.e., "return to service". The method is a combination of three variables that, combined, provide for the enhanced overall effectiveness of the method. The three variables are as follows; a) 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. |
