The road surface of cement concrete in highway is easily cracked and even destroyed due to inhomogeneous subsiding of the road foundation. In this work, a super-thin-coating material is prepared in order to repair the destroyed thin road surface, in which polymers and steel-fibers are added into ordinary concrete to form a steel fiber reinforced polymer-cement-based composite. the composite was successfully used to repair road surface. Microstructure and mechanical properties of the composites are measured and analyzed.
