Problems solved by technology

[0003] At this stage, the asphalt modification method is usually used to improve the service life of asphalt pavement and delay the overhaul time, but the asphalt prepared by the commonly used shearing machine modification method has disadvantages such as easy aging, poor storage stability, and complicated modification process; and the traditional In order to prevent temperature segregation, modified asphalt needs to be heated in advance during production, and storage tanks and heating insulation will be occupied if it cannot be used up at one time, resulting in a large waste of energy

Abstract

The invention provides a construction method for a high viscosity modified asphalt pavement. The construction method comprises the following steps of S1, preparing construction equipment; S2, designing a mix proportion of high viscosity modified asphalt and a mix proportion of a high viscosity modified asphalt mixture and carrying out waterproof bonding layer treatment on the pavement; S3, stirring the high viscosity modified asphalt mixture and directly putting the viscosity modified asphalt into an asphalt mixture mixer to be mixed by using a putting device; S4, transporting the high viscosity modified asphalt mixture to a construction site; S5, carrying out preparation work before paving the high viscosity modified asphalt mixture; S6, selecting and adjusting using parameters of a paver; S7, carrying out paving operation; S8, grinding and forming the high viscosity modified asphalt mixture; and S9, carrying out joint treatment. The high viscosity modified asphalt can be directly putin the asphalt mixture mixer to be dry-mixed with an aggregate without being sheared and modified at a high temperature. An application process is simple and easy to operate, and health of productionstaff is further facilitated and adverse effects to the ecological environment are reduced.

Description

technical field [0001] The invention belongs to the field of road construction, and in particular relates to a construction method for high-viscosity modified asphalt pavement. Background technique [0002] With the rapid development of China's highway industry, asphalt pavement has the advantages of good driving comfort and convenient maintenance and repair, and has developed into the main pavement structure form of high-grade highways. In recent years, the traffic volume has grown rapidly, and the phenomenon of large-scale and overloaded vehicles has become increasingly prominent, which puts forward higher requirements for the technical performance of asphalt pavement materials. [0003] At this stage, the asphalt modification method is usually used to improve the service life of asphalt pavement and delay the overhaul time, but the asphalt prepared by the commonly used shearing machine modification method has disadvantages such as easy aging, poor storage stability, and c...
