Asphalt pavement preventative maintenance material and intelligent pulverizing device thereof

Abstract

The invention discloses an asphalt pavement preventive maintenance material and an intelligent crushing device thereof. The asphalt pavement preventive maintenance material is a glass fiber geogrid structure made of glass fiber, and the invention discloses an intelligent crushing device. The glass fiber geogrid of the present invention has high tensile strength, low elongation, no long-term creep, high thermal stability, strong compatibility with asphalt mixing, unaffected physical and chemical stability, interlocking of aggregates and limited hindrance The movement of the aggregate is controlled, so that the asphalt mixture can achieve better compaction under load, higher load-bearing capacity, better load transfer performance and smaller deformation; the main components of glass fiber are: Silicon oxide is an inorganic material with extremely stable physical and chemical properties. The structure of the crushing device is simple, and the internal debris is easy to clean. The fixed cutting tool and the rotating cutting tool are in a rotating cutting state during work, which makes the asphalt pavement preventive maintenance materials crushed more thoroughly. .

Description

technical field [0001] The invention belongs to the technical field of pavement maintenance, and in particular relates to a preventive maintenance material for asphalt pavement and an intelligent crushing device thereof. Background technique [0002] In the Spring Festival of 2008, severe freezing disasters occurred in the central and southern regions of my country, among which Guizhou and Hunan provinces were the most serious. Taking Guizhou Province as an example, this rare ice disaster has had a serious impact on the transportation industry in Guizhou Province. According to statistics, the road traffic in nine districts (states, cities) in the province has been affected to varying degrees, and the direct economic loss has reached 1.4 billion yuan. The number of days with the average temperature of the province below 1°C in a row, the number of days with large-scale continuous low temperature, and the severity of the impact are the extreme values ​​since 1951. The lowest ...

Problems solved by technology

[0012] The purpose of the present invention is to provide a preventive maintenance material for asphalt pavement and its intelligent crushing device, which aims to solve the problem that under the climate conditions of plateau and humid mountainous areas, the pavement is prone to icing in winter, greatly reducing the anti-skid ability of the pavement, and easily causing vicious traffic accidents , and in the current waste silk crushing process, the life cycle of the crushing device is short and the function is single
