[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown, a joint edge treatment structure for asphalt pavement and concrete pavement includes:

[0025] Example 1

[0026] The pre-cast concrete roadbed 1 is excavated to form the towing portion 2.

[0027] The excavated towing portion 2 is formed with a first protruding portion 21 in the shape of a rectangular block distributed along the side of the towing portion 2 and a second protruding portion 22 in the shape of an isosceles trapezoid on the towing portion 2.

[0028] Further, in combination with Figure 2 It can be seen that the first protruding portion 21 and the second protruding portion 22 form a first recessed groove 23 therebetween, and a plurality of holes 5 are formed in the first recessed groove 23 in a matrix distribution. The plurality of holes 5 are at least two rows, and each row has at least two holes 5.

[0029] The second protruding portion 22 has a second recessed groove 24 formed between the adjacent side edges of the concrete roadbed 1.

[0030] Further, in the above embodiment, the height of the first protruding portion 21 and the second protruding portion 22 is consistent, and the distance between the top and the upper surface of the concrete roadbed 1 is 10-15 cm.

[0031] In the above technology, the first protruding portion 21, the second protruding portion 22, the first recessed groove 23, and the second recessed groove 24 are formed by pre-excavating the concrete roadbed 1, so that the formed asphalt pavement 3 can be attached to the towing portion 2 to increase the contact area, and the combination strength of the concrete roadbed 1 and the asphalt pavement 3 is increased by the concave-convex contact surface structure design.

[0032] Embodiment Two
