Problems solved by technology

In the daily maintenance and repair work of asphalt pavement, the maintenance of potholes is relatively frequent, easily affected by traffic volume and external environment, and the maintenance is difficult. If the potholes are not repaired in time, it will not only accelerate the damage of the road surface, but also cause damage to vehicles. and drivers also pose a greater threat
Practice has shown that traditional repair materials are not suitable for heavy-duty traffic roads in mountainous areas and complex climate conditions of high temperature and rain in hot and humid areas, and cannot meet the needs of road durability. Problems such as water d

Example Embodiment

[0027] Example one

[0028] Construction preparation:

[0029] Equipment used for repairing potholes: road cutters, mixers, road blowers, milling machines, drilling machines, steel brushes, etc.

[0030] Repair materials: Portland cement, sulphoaluminate cement, emulsified asphalt, high-efficiency polycarboxylic acid water reducer, carbon black, etc.

[0031] See attached figure 1 During the specific implementation, the repair of the potholes on the asphalt pavement includes the following steps:

[0032] Step 1: Mix design of materials for quick repair of asphalt pavement. According to the site's natural environment and construction conditions, the optimal mix ratio of materials is designed through the setting time, slump and other indicators before the construction starts. The mix ratio used is:

[0033]

[0034] Step 2: Determine the pit repair window in advance according to the size and depth of the pit. The window range is expanded by 10cm to the surroundings according to the actu...

Abstract

The invention discloses an asphalt pavement pot hole quick repairing material and a repairing method thereof, wherein the raw materials comprise Portland cement, sulphoaluminate cement, emulsified asphalt, aggregate, water, a water reducing agent and a color adjusting agent carbon black according to a mass ratio of 1.0: (1.0-1.7):(0.8-1.0):(5.2-7.0):(1.0-1.35):(0.024-0.03):(0.08-0.11). According to the present invention, the obtained quick repairing material is suitable for the repairing of asphalt pavement pot holes with high traffic volume and serious overload, has characteristics of rapid traffic open, high early strength, good toughness, strong durability, strong impact resistance, low environmental impact on construction and the like, has the color adapted to the original asphalt pavement, further has advantages of strong adhesion and good integrity, and can effectively reduce the probability of secondary damage after the repairing of the asphalt pavement pot hole, wherein generally the traffic can be opened in 1 h.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement maintenance, in particular to a quick repair material for asphalt pavement and a repair method thereof. Background technique [0002] With the vigorous development of my country's economic construction and urban modernization, highway transportation facilities, as a key project, have also developed rapidly in the past 30 years. As of the end of 2018, the total mileage of national highways was 4,846,500 kilometers, and the total mileage of road maintenance also reached 4,757,800 kilometers, accounting for 98.2% of the total mileage of highways. Therefore, the main problem of my country's highway construction at this stage is how to take effective measures to repair the "problem road", improve the driving safety and comfort of the "problem road", and prolong its service life to achieve the purpose of saving maintenance costs. [0003] Through the investigation of asphalt pavement disease d...
