A kind of emulsified asphalt slurry mixture penetrating asphalt pavement

Abstract

The invention provides a mixture for constructing an emulsified asphalt and dilute slurry mixture bituminous penetration road. The mixture is an FH-40 type mixture, and the bituminous road constructed by using the mixture can achieve an effect of preventing tracks. The mixture can be used for maintenance of new roads and constructed roads, and can also be used as a protective layer, a wearing layer and an anti-skid layer and used for paving a bridge deck, beautifying, preventing noise and filling tracks. In the emulsified asphalt and dilute slurry mixture bituminous penetration road, the maximum gravel diameter of the aggregate is consistent with the thickness of the road; a suspended compact bituminous mixture, which forms skeletons and is padded between the skeletons and formed by gravels of other diameters and bituminous cement, is a unity of a skeleton structure and a suspended compact structure, called as a skeleton-suspended compact composite structure, abbreviated as a composite structure and expressed as 'FH'; and 40 expresses that the maximum diameter of the scattered gravel is 40mm, and is also the thickness of the road.

Description

technical field [0001] The invention relates to a material used for asphalt pavement, in particular to an emulsified asphalt slurry mixture penetrating asphalt pavement. The asphalt pavement built with this material can prevent rutting and ensure road use quality. 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 sus...

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
