Problems solved by technology

Usually, a single polymer is used to improve its physical and mechanical properties, and often the bonding performance, high temperature resistance and other properties are improved, and its low temperature resistance and durability cannot be taken into account, and the research on multi-polymer composite modification is not enough.
[0006] (3) It is difficult to meet the opening-to-traffic requirements of rapid repairs such as large pits and large cracks
[0007] (4) Long setting time, poor construction effect, cumbersome operation, long repair and health maintenance period, affecting traffic opening
[0008] (5) The flatness of the ultra-thin repaired road is poor, which reduces the use function and aesthetics of the road surface
This brings confusion to the rapid repair of municipal roads and bridges, so it is imminent to develop new materials for normal temperature construction

Abstract

The invention discloses a preparation method for a normal-temperature rapid repairing material for municipal roads and bridges and construction steps of the preparation method. According to the preparation method, a normal-temperature quick-strengthened asphalt composite emulsion is prepared by using a 'chemical network cross-linking emulsion technique', that is, a rapid normal-temperature composite emulsion-based repairing material for roads and bridges. The material is developed on the basis of modified emulsified asphalt and in addition is a high-tech environmental-friendly product which is particularly added with a tackifying and toughening aqueous polymer emulsion and is compounded under certain process conditions.

Description

technical field [0001] The invention belongs to the field of cement polymer emulsion, and in particular relates to a preparation method and construction steps of a normal-temperature rapid repair material for municipal roads and bridges. Background technique [0002] With the development of society, the traffic volume has increased significantly, and the transportation has the characteristics of "heavy load, large flow and channelized traffic". With the rapid growth of traffic volume and the aggravation of overloading and overloading, a large number of new roads have been open to traffic within 1-2 years, and early damages such as rutting, congestion and pushing have appeared to varying degrees. In order to keep the municipal roads in a good state of economic operation, the state requires frequent maintenance and repairs of the roads to prevent further aging and wear and tear of the roads. However, in urban centers with heavy municipal traffic and dense crowds, how to quick...
