specific Embodiment approach 1
[0030] Embodiment 1: The continuous prefabricated asphalt pavement in this embodiment is composed of a prefabricated asphalt pavement slab, an upper layer 6, a cushion layer 7 and a soil foundation 8;
[0031] The cushion layer 7 is arranged on the upper surface of the soil foundation 8, the prefabricated asphalt road slab is arranged on the upper surface of the cushion layer 7, and the upper layer 6 is arranged on the upper surface of the prefabricated asphalt road slab and bonded by an emulsified asphalt adhesive;
[0032] The prefabricated asphalt road slab is composed of a plurality of prefabricated slab units; the prefabricated slab unit is composed of a base layer 1, a lower layer 2 and a middle layer 3; the lower layer 2 is arranged on the upper surface of the base layer 1 and bonded by an emulsified asphalt adhesive , the side of the lower layer 2 is set on the inner side of the side of the base layer 1, the middle layer 3 is set on the upper surface of the lower layer ...
specific Embodiment approach 2
[0037] Specific Embodiment 2: The difference between this embodiment and Specific Embodiment 1 is that the double-tenon coupling block is composed of two tenons 5 with the same shape and matched with the tenon groove 4. One end of the tenon 5 is a larger end surface, and the other end is The smaller ends of the two mortises 5 are relatively fixed. Other steps and parameters are the same as those in the first embodiment.
specific Embodiment approach 3
[0038] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the tenon groove 4 is a trapezoidal groove, and the smaller bottom side of the tenon groove 4 is an opening. Other steps and parameters are the same as those in the first embodiment.
