ABSTRACT
ABSTRACT: Cement concrete pavement becomes one of the two kinds of road surfaces in our country for its high strength and excellent durability. With the development of national economy and intense increase of traffic, cement concrete road surface has undergone worsening damage, among which cracks are the most common phenomena. The new grouting material of cement-based/polymer composite is a method of comprehensive grouting. Its stone body is a network formed by intertwining of high polymer and inorganic material. Its rigidity is between common cement concrete and asphalt concrete. Its pressive strength can reach 3-5 Mpa in days. As a semi-rigid material, it has low temperature sensibility, excellent ability of crack resistance and impermeability. It matches basically the elasticity modulus of the roadbed material, and thus is suitable to be used as grouting material to prevent the void slabs from permeation as well as reinforce them.
