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.
Claims14
A reinforced cement concrete composition selected from asphalt cement concrete composition 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 treatment composition which 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 cement concrete selected from asphalt cement concrete and portland cement concrete, comprising:
- providing a plurality of reinforcement fibers, each of the plurality of reinforcement fibers forming a substrate having an outer surface;
- applying graft initiator to said outer surface of said plurality of reinforcement fibers;
- 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 plurality of treated fibers;
- and
- adding said plurality of treated fibers to a mixture during preparation of the asphalt and portland cement concrete prior to its placement.
