Reuse of scrap concrete slab in highway reconstruction

When reconstructing road on old line, the reuse of waste concrete has a great meaning for environment and construction cost. The physical and mechanical parameters of regenerated concrete that is based on waste concrete were measured. The parameters can reach the demand of standards. The testing road operation shows that the regenerated concrete can be used as semi-rigid base materials. Compared with common concrete, the anti-wear feature of regenerated concrete is not good enough, its other parameters have no difference.
