Construction process for enhancing durability of toll station square road

Abstract

The invention relates to a construction process for enhancing the durability of a toll station square road. The construction process comprises the following steps: S1, a roadbed is paved; s2, after the surface of the roadbed is cleaned, a first asphalt bonding layer is sprayed, and then a cement stabilized macadam layer is laid on the asphalt bonding layer; s3, an asphalt waterproof layer is sprayed on the cement stabilized macadam layer; s4, after the asphalt waterproof layer is dried and hardened, a second asphalt bonding layer is sprayed, and then a coarse-graded asphalt concrete layer is paved; s5, a third asphalt bonding layer is sprayed on the surface of the paved coarse-graded asphalt concrete layer, and then a dense-graded asphalt concrete layer is laid; and S6, an anti-scattering asphalt layer is sprayed on the dense-graded asphalt concrete layer. The durability of the toll station square pavement structure can be improved through the construction process.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a construction technique for enhancing road durability of a toll station square. Background technique [0002] The toll plaza is an indispensable part of the expressway, but due to the small pavement area, the material durability and structural durability of the existing toll plaza pavement construction has not been studied in combination with its load characteristics. It is simply to follow the road structure of the main line. However, in the asphalt pavement construction of the toll plaza, due to the excessive rolling action of road rollers or other heavy machinery, it is easy to cause damage and loss of the asphalt film, and in severe cases, it may even cause stones to drop, break, etc., resulting in partial asphalt mixture. The decrease of cohesion will affect the construction quality of asphalt pavement, shorten the service life of pavement, and cause more serious damage to...

However, in the asphalt pavement construction of the toll plaza, due to the excessive rolling action of road rollers or other heavy machinery, it is easy to cause damage and loss of the asphalt film, and in severe cases, it may even cause stones to drop, break, etc., resulting in partial asphalt mixture. Cohesion decline phenomenon affects the construction quality of asphalt pavement, shortens the service life of pavement, and causes more serious damage to drainage asphalt pavement
