The invention discloses an impacting-resistant and abrasion-resistant concrete prefabricated road. The impacting-resistant and abrasion-resistant concrete prefabricated road comprises four prefabricated boards. Holes where steel strands are contained are formed in the two sides of the prefabricated boards respectively. The adjacent prefabricated boards are connected through the steel strands. The diameter of the steel strands is 14.50 mm. Or holes where the steel strands are contained are formed in the four sides of the prefabricated boards, and the adjacent prefabricated boards are connected through the steel strands. The four prefabricated boards form a road surface unit through the corresponding steel strands and steel connecting board bands on the outer sides of the prefabricated boards. Connecting key structures are further installed between the adjacent prefabricated boards. Each connecting key structure comprises a shearing-resisting convex key and a shearing-resisting concave key which are matched. The prefabricated boards are made of cement, coal ash, sand, water, nylon fibers, barium nitrate, calcium lignosulphonate, silicon carbide powder, sepiolite powder, alumina silicate fibers and gypsum.
