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.

Claims (19)

1. A polymer modified Portland cement pavement overlay product for application on all pavement surfaces, comprising in combination:

component A: latex/polymer emulsion, having a polymer solids content of 54.1 to 58.6 percent by weight;

component B, a dry powder blend of Type I Portland cement (1 part) and a sand (3 parts) blend of 60-120 mesh washed silica sand;

component C, a #4 sized quartz non-skid aggregate; and,

water,

the foregoing Components A, B, and C mixed such that a proportion of Component A is provided in a range of about 55 gallons for every 2800 lbs of Component B and is mixed with 100 lbs of Component C along with 20-25 gallons of said water until free of powder pockets and air voids, said #4 aggregate being held in suspension in said product, and said product applied to overlay said pavement surface at a thickness of ⅛ to ½ inches.

2. An overlay product as in claim 1 , wherein:

said component A latex/polymer emulsion, has a polymer solids content of about 58 percent by weight.

3. An overlay product as in claim 1 , wherein:

said product is extruded onto said pavement surface.

4. A kit for preparing a polymer modified Portland cement pavement overlay product for application on all pavement surfaces, said kit comprising in combination:

55 gallons of component A: latex/polymer emulsion, having a polymer solids content of 54.1 to 58.6 percent by weight;

2800 lbs of component B, a dry powder blend of Type I Portland cement (1 part) and a sand (3 parts) blend of 60-120 mesh washed silica sand;

100 lbs of component C, a #4 sized quartz non-skid aggregate; and,

the foregoing kit Components A, B, and C are mixed along with about 20-25 gallons of water until free of powder pockets and air voids, said #4 aggregate being held in suspension in said product, and said product applied to overlay said pavement surface at a thickness of about ⅛ to ½ inches.

5. A kit as in claim 4 , wherein:

said component A latex/polymer emulsion, has a polymer solids content of about 58 percent by weight.

6. A kit as in claim 4 , wherein:

said product created from said kit is extruded onto said pavement surface.
