Construction method for highway for load bearing vehicle

Abstract

The invention relates to the field of the construction technology of expressways, in particular to a construction method of the expressways for bearing trucks, which solves the problems of the increasing maintenance cost of the existing highways caused by failure to bear heavy loading, frequent cracks and even collapses. The construction steps include that: a concrete bedding is cast by concrete with a strength degree between C80 and C100; before the rolling of each layer of the soil body roadbed, liquid flocculant with the concentration between 1per mill and 2 per mill are evenly sprayed on the surface of each layer of the soil body, wherein a kilogram of liquid flocculant per square meter is sprayed for the soil body surface; for the fabrication process of the asphalt layers, particles made by waste rubbers, dimethylbenzoyl, acrylonitrile, peroxidation dialkyl, hydroxymethyl cellulose, and fibers are added during the heating process of the asphalt. Since the three steps are combinedduring the construction, an excellent loading capacity is realized for the expressways and the running of overloading and overrunning vehicles are fulfilled. The construction method of the expresswaysfor bearing heavy trucks has the advantages of remarkably prolonging the service life of the expressways, reducing maintenance costs, and having a certain economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of highway construction, in particular to a construction method for a load-bearing vehicle highway. Background technique [0002] At present, with the rapid development of the national economy, the construction mileage of expressways has also increased rapidly, but the subsequent maintenance costs for roads have also greatly increased. The main reasons for this are the following two. First, the rapid development of the national economy The rapid increase in traffic flow and the increase in heavy-duty vehicles, especially the widespread severe overloading, have led to frequent early damage to expressways built in recent years. 60 tons, but the tonnage of the current vehicle load exceeds 100 tons, which objectively increases the pressure on the maintenance of expressways in our country. Second, the strength grade of the concrete cushion of the expressway is designed according to the tonnage of the current car...
