Embodiment 1
[0030] Embodiment 1 A normal temperature rapid repair material and repair method for asphalt pavement rutting disease, comprising:
[0031] 1. Material preparation
[0032] Select the modified emulsified asphalt, rapid cement, coarse aggregate and fine aggregate with a mass ratio of each material of 1.0:1.2-1.6:5.5-5.9:3.6-4.0;
[0033]
[0034]
[0035] Among them, the modified emulsified asphalt is a slow-cracking cationic modified emulsified asphalt, which is composed of the following components according to weight percentage: asphalt 51-55%, cationic emulsifier 1.5%-2.2%, modifier 5.0-5.5%, pH adjustment 3.1-5.0% additive, the balance is water; rapid cement consists of sulphoaluminate cement, early strength water reducer, basalt fiber and toner; the size of coarse aggregate is 4.75-13.2mm, and the coarse aggregate is selected from stone One of rice, limestone and granite gravel; the specification of the fine aggregate is 0-4.75mm, and the fine aggregate is selected ...

Abstract
The invention relates to the technical field of pavement rut repairing, in particular to a normal-temperature rapid repairing material for asphalt pavement rut diseases and a repairing method of the normal-temperature rapid repairing material. The rapid repairing material comprises the following raw materials: modified emulsified asphalt, rapid cement, coarse aggregate and fine aggregate. The rapid repairing material provided by the invention does not need to add water during mixing, the emulsified asphalt forms strength after demulsification, water required by cement hydration is provided, the activity of the quick cement can promote demulsification of the emulsified asphalt, and the quick cement and the emulsified asphalt jointly accelerate the final setting time of the repair material and quickly improve the early strength. The rapid repairing material is suitable for repairing high-traffic-volume and serious-overload asphalt pavement ruts and pit slots, has the characteristics of no need of traffic closing, high early strength, good toughness, strong binding power, strong durability and impact resistance, small environmental influence on construction and the like, and can be finally set to form strength generally 20 minutes after mixing.
Description
technical field [0001] The invention relates to the technical field of pavement rutting repair, in particular to a normal-temperature rapid repair material for asphalt pavement rutting disease 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. By the end of 2020, the total mileage of national highways was 5,198,100 kilometers, and the density of roads was 54.15 kilometers per hundred square kilometers. Master" to "combination of self-cultivation". 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...
