Abstract
The invention relates to coating compositions, treated reinforced fibers, reinforced asphalt and portland cement concrete and methods for producing the same. The coating compositions include monomer, prepolymer or mixtures thereof, and graft initiator. The monomer and/or prepolymer include at least one functional group selected from the group consisting of hydroxyl, carboxyl, amino and ester. The graft initiator includes metallic salt.
Claims12
A coating composition for treating reinforcement fibers, comprising:
- a component selected from the group comprising monomer, prepolymer and mixtures thereof, wherein said component comprises at least one functional group selected from the group consisting of hydroxyl, carboxyl, amino and ester;
- and
- a graft initiator comprising metallic salt.
A reinforced asphalt and portland cement concrete composition, comprising:
- a plurality of reinforcement fibers each having an outer surface and a treatment layer formed on the outer surface, the treatment layer comprises:
- a component selected from the group consisting of monomer, prepolymer and mixtures thereof, wherein said component comprises at least one functional group selected from the group consisting of hydroxyl, carboxyl, amino and ester;
- and
- a graft initiator comprising metallic salt;
- aggregate;
- and
- binder.
A method of reinforcing asphalt and portland cement concrete, comprising:
- providing reinforcement fiber substrate having an outer surface;
- applying graft initiator to said outer surface of said reinforcement fiber substrate;
- applying to said graft initiator a component selected from the group consisting of monomer, prepolymer and mixtures thereof, said component comprising at least one functional group selected from the group consisting of hydroxyl, carboxyl, amino, ester and mixtures thereof to form a treated fiber;
- and
- adding said treated fiber to the asphalt and portland cement concrete.
