Embodiment 1

[0036] figure 1 The flow chart of the construction method of the highway pavement structure that this embodiment provides, figure 2 for adoption figure 1 For a schematic diagram of the pavement structure of a highway built with the construction method shown, see figure 1 and figure 2 .

[0037] The construction method of the highway pavement structure provided by this embodiment can be well applied to the construction of semi-rigid bases and sub-bases of roads of all grades, especially for the construction of semi-rigid bases of rural roads, which includes the following steps:

[0038] S1, laying a cushion, laying gravel or 12% lime soil on the roadbed to form the cushion.

[0039] Such as figure 2 As shown, the underlayment 100 serves as the bottom layer of the highway pavement structure and is used for direct contact with the roadbed. In this embodiment, the cushion layer 100 can be formed by gravel or 12% lime soil, wherein the 12% lime soil refers to a mixture of ...

Abstract

The invention provides a highway pavement structure and a construction method thereof and relates to the technical field of highways. The construction method of the highway pavement structure comprises the following steps that S1, a cushion course is paved; S2, a base course is paved, specifically, aggregates are spread on the cushion course in a layered mode according to the predetermined width and thickness through a stone spreader and are leveled through a land leveler, then, cement is uniformly spread on the aggregates according to the determined dosage through a powder spreader to form the base course, the cement content range of the base course is 4.5%-5.5%, and the water content range of the base course is 5.0%-6.5%; and S3, a surface course is paved. According to the construction method, a stabilized soil mixing station and a high-voltage input circuit do not need to be built; in addition, procedure connection is compact, the degree of mechanization is high, in-situ control is facilitated, and secondary reversed transport of the aggregates is avoided; and especially, the construction method has remarkable construction benefits in agricultural and pastoral areas.
