As shown in fig. 1, an anti-slip asphalt pavement structure comprises a concrete pavement layer 1, an asphalt pavement base layer 3 and an upper asphalt pavement layer 4 which are sequentially arranged; be provided with anti-slip stake 2 between concrete pavement layer 1 and the asphalt pavement foundation layer, and be provided with a plurality of anti-slip recesses 5 between asphalt pavement foundation layer 3 and the last asphalt pavement layer 4, and a plurality of anti-slip recesses 5 equidistant interval sets up respectively.

Compared with the prior art, when the urban road is multiplied in use frequency in the prior art, the road bearing pressure is high, and the bearing capacity of the old cement concrete pavement structure constructed in a large number of early years cannot be suitable for design requirements due to the influence of natural disasters, extreme weather and the like, and various disease phenomena are generated under the repeated load action; therefore, the driving comfort is poor, the speed of the vehicle is difficult to improve, and the like. Therefore, the cement pavement with cracks is required to be upgraded and modified, and the modification mode is to additionally pave a layer of asphalt on the basis of the original concrete pavement. The pavement adding mode can be used for rapidly upgrading and reforming the pavement. However, it is inevitable that the asphalt pavement layers are weak parts of the pavement structure, and under heavy vehicle load, the pavement layers are easy to slip and break with the pavement bottom layers. In order to solve the problem of slip damage, grooves are formed in the concrete pavement layer 1, when asphalt is paved, the asphalt flows into the grooves, an anti-slip structure is formed, and the anti-slip capability between asphalt pavement layers is improved through the anti-slip structure. In the utility model, anti-slip structures are respectively formed between the concrete pavement layer 1 and the asphalt pavement base layer 3 and between the asphalt pavement base layer 3 and the upper asphalt pavement layer 4, so that the anti-slip capability of the additionally paved asphalt pavement can be effectively further improved.

The anti-slip piles 2 and the anti-slip grooves 5 form mechanical engagement between the layers, respectively.

The concrete pavement layer 1 is provided with a plurality of concave grooves, and filling blocks are formed in the concave grooves to form the anti-slip pile 2. The anti-slip grooves 5 are formed by pressing through a road roller after the asphalt is paved for the first time. The anti-slip groove 5 is of a hemispherical arc structure.

A waterproof bonding layer is also arranged between the asphalt pavement base layer 3 and the upper asphalt pavement layer 4.

In actual use, when the old road is reformed, a plurality of pile grooves are firstly formed in the original concrete pavement layer 1 on the original old road in an excavating mode. When the asphalt of the first foundation layer is paved, the asphalt in a hot melting state flows into the pile groove, and after the asphalt is condensed, an anti-slip pile 2 is formed in the pile groove, so that a first anti-slip structure is formed between the asphalt pavement foundation layer 3 and the concrete pavement layer 1. After the asphalt pavement base layer 3 is sufficiently cooled and solidified, the bottom layer is compacted for 1 time by using the road roller, and in the process, the road roller is provided with a plurality of grooves which are arranged at equal intervals on the asphalt pavement base layer 3 through a die in a stroke manner, and the road roller can be particularly arranged to be hemispherical. The asphalt pavement layer 4 is then laid down and a second anti-slip structure is formed. The anti-slip performance of the concrete rear layer can be effectively improved through the arrangement of the two anti-slip structures when the concrete rear layer is reformed.

The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
