Abstract

The invention discloses a paving method of an anti-rutting asphalt pavement. The paving method comprises the following steps: cleaning a roadbed layer, and sequentially paving an epoxy asphalt bonding layer, a gravel layer, a first reinforcing layer, a first bonding layer, a second reinforcing layer, a second bonding layer, an embedded stone layer and an asphalt surface layer on the surface of the roadbed layer, wherein the particle size of gravel in the gravel layer is 5-6 mm, the particle size of embedded stone in the embedded stone layer is 9-12 mm, the top of the gravel layer is embedded into the first reinforcing layer, the bottom of the embedded stone layer is embedded into the second bonding layer, and the top of the embedded stone layer is embedded into the asphalt surface layer. According to the above technical scheme, the paved pavement is high in structural stability, an asphalt surface layer can be effectively prevented from sliding, and the rutting resistance of the asphalt pavement is improved.

Description

technical field [0001] The invention relates to the field of road design. More particularly, the present invention relates to a method of laying a rutting-resistant asphalt pavement. Background technique [0002] With the increase of highway traffic volume in our country year by year, under the action of high temperature and continuous load, the asphalt pavement is prone to slippage between the surface layers or the stability of the pavement structure is insufficient, which is prone to deformation and rutting. The appearance of rutting on asphalt pavement seriously affects the service quality of high-grade pavement and driving safety, and directly affects the service life of asphalt pavement, resulting in the increase of maintenance cost and constitutes a safety hazard of transportation. Contents of the invention [0003] An object of the present invention is to solve at least the above-mentioned problems and provide a method for laying an anti-rutting asphalt pavement. T...
