Example Embodiment
[0035] Example 1:
[0036] This embodiment provides an asphalt concrete pavement structure, such as figure 1 As shown, it includes a soil foundation 1. A cushion layer 2, a base layer 3 and a surface layer 4 are laid on the soil foundation 1 from bottom to top. A layer of filter fabric 5 is laid between the soil foundation 1 and the cushion layer 2. The filter fabric 5 is made of non-woven geotextile, the specification is 300g / m 2 , Its function is to prevent the fine soil from entering the soil foundation 1 and causing damage to the soil foundation 1. The cushion layer 2 is made of construction concrete slag, the width of the cushion layer 2 is 25cm wider than the side of the soil foundation 1, and the base layer 3 uses gravel slag Mixture, the width of the base layer 3 is the same as the width of the cushion layer 2, and the width of the surface layer 4 is narrower than the side of the base layer 3 by 5 cm on each side; the surface layer 4 includes a lower layer 41, a middle sur...
