Problems solved by technology

[0012] However, the current technology has the following disadvantages: in the process of synchronous sealing, there are too many gravels, which will overlap after spreading, which is due to insufficient adhesion of gravels and waste tire asphalt film, and the cohesive force decreases;

Abstract

The invention provides a method for synchronous coat-sealing by using waste tire rubber asphalt according to the particle size of crushed rock, which adopts the following technical scheme: the method mainly comprises the following steps of: confirming the particle size of the crushed rock, crushing waste tires, grinding the crushed waste tires into powder, screening ingredients, and carrying out synchronous coat-sealing on the crushed stones, wherein in the process of implementing the formula, when the particle size is 9.5-13.2mm, the use quantity of the crushed stone is 14kg / m<2>, and the use quantity of the waste tire rubber asphalt is 2.2kg / m<2>; and when the particle size is 4.75-9.5mm, the use quantity of the crushed stone is 11.2kg / m<2>, and the use quantity of the waste tire rubber asphalt is 1.8kg / m<2>. The method disclosed by the invention has the following advantages that: the technical process is detailed, phenomena of a reduced cohesive force and a too thick waste tire asphalt film are avoided, and the use quantities of different waste tire rubber asphalts can be confirmed according to the particle size of the crushed stone; thus, the asphalt film can be prevented from exposure, the wrapping force of the crushed stone is increased, and the adhesive force of the waste tire rubber asphalt and the crushed stone can be effectively ensured.

Description

Technical field: [0001] The invention relates to a method for synchronous sealing of waste tire rubber asphalt according to the particle size of gravel. Background technique: [0002] Synchronous bituminous gravel sealing technology was invented in Europe in the 1950s. It was initially a simple asphalt (emulsified asphalt) spreading and artificial shovel spreading 0-10MM gravel (or river sand) to quickly repair cracked and dull pavement. The method of the early disease of road surface such as oily, pockmarked surface; With the development of science and technology, in the early 1980s, there were asphalt spreading (emulsified asphalt) vehicles and gravel spreading machines with a high degree of mechanization, and the construction efficiency was greatly improved; but due to Due to the limitation of material development at that time, this construction method was only used for the maintenance and construction of urban and rural roads and rural roads; after the rapid development ...
