Construction technology of emulsified asphalt slurry mixture penetrating asphalt pavement

Abstract

The invention provides an emulsified asphalt thin paste mixture penetration type asphalt pavement construction technology which can achieve an effect that tracks cannot be generated on an asphalt pavement prepared by the technology. The construction technology comprises the steps of adhering gravels playing a main supporting role to a lower bearing layer according to a layer spreading method, penetrating a stirred emulsified asphalt thin paste mixture into clearances among the gravels, performing preservation I, preservation II and preservation III, and rolling to form the asphalt pavement. During implementation of the construction technology, all sets of equipment are a small amount of conventional mechanical equipment which are small in size and simple; the construction technology is simple, easy to master, low in consumption, environment-friendly, healthy and safe; the construction technology disclosed by the invention can be used for maintaining new constructed pavements and constructed pavements, and the asphalt pavement can be also used as a protection layer, an abrasion layer and an antiskid layer and used for paving a bridge surface, beautifying the environment or avoiding noise and the like; the construction technology can be used for filling the tracks and is particularly suitable for climbing roads on expressways, exclusive BRT (bus rapid transit) roads and guide roads and positions, at which deeper tracks are generated, on the middle layer or the lower layer of a multi-layer asphalt pavement.

Description

technical field [0001] The invention relates to the technical field of road construction and maintenance, in particular to an emulsified asphalt slurry mixture penetration type asphalt pavement construction process. Background technique [0002] Most of the roads and urban roads that have been built in my country are asphalt roads. Due to the serious overloading of vehicles, large traffic volume, channelized driving, and high temperature weather, rutting has become the most important disease in the early stage of asphalt pavement, such as the climbing section of the expressway, the BRT (Bus Rapid Transit) lane and Rutting is the most likely and serious place on the guide road, etc. According to the data, 80% of the asphalt pavement has different degrees of rutting. It is a stubborn disease in road diseases and has not been solved. [0003] At present, the typical asphalt pavement structure is divided into three types: the suspended dense structure is shown in Figure 1(a), t...

AI Technical Summary

Problems solved by technology

SMA (asphalt mastic macadam) asphalt pavement is such a pavement. Theoretically speaking, its anti-rutting performance is very strong. Relatively low, unstable performance of mechanical equipment, relatively low softening point of binder, material segregation and other factors lead to relatively insufficient anti-rutting performance of SMA asphalt pavement. The fact is that SMA asphalt pavement also often appears rutting
