Again, I maintain that we should use the flexural-tensile strain and the vertical shearing stress of the bottom of cover of the joint as the target for the design of the cover structure of asphalt on the old cement concrete. In addition, on the basis of much theoretical analysis, I preliminarily put forward to a designing methods to anchor the old cement concrete road by using dog irons made of iron bars and then covering it using asphalt concrete structure. Finally, through selecting the plan of the cover of the road to be experimented, and making a detailed introduction to the techniques of construction according to the result of theoretical analysis, I know that after anchoring the slabs close to each other with dog irons made of iron, and then cover them using asphalt cement concrete has an obvious effect on preventing and slowing down the reflection cracks in the bituminous concrete skin coat over the old road.
