　　The asphalt overlay layer on the old cement concrete pavement mainly serves the functional use of the pavement, but does not contribute much to the bearing capacity. The rigid concrete pavement under the overlay layer still plays a key bearing role. However, the asphalt overlay on the old asphalt concrete pavement with geomembrane prices is different, as the asphalt overlay will be carried together with the old asphalt concrete pavement. Therefore, the price of geomembrane for asphalt overlay on asphalt concrete pavement will not only cause reflection cracks, but also fatigue cracking due to long-term loading. We conducted a stress analysis on the asphalt overlay layer on the old asphalt concrete pavement: due to the fact that the asphalt overlay layer is a flexible surface layer with the same properties as the asphalt overlay layer, when subjected to load, the road surface will bend. When the asphalt overlay directly contacts the wheel is subjected to pressure, and in the area outside the wheel load edge, the surface layer is subjected to tensile force. Due to the different force properties of the two stress areas and their mutual nature, sudden changes in force are prone to occur at the junction of the two stress areas. Fatigue cracking occurs under long-term loading. The geomembrane on the slope should be laid from top to bottom without splicing. The joints at corners should avoid corner ditches as much as possible. The geomembrane should be wholesale and irregular shapes should be minimized as much as possible.
