Problems solved by technology

[0002] Due to the current requirements for air pollution control, road sprinkling has become the norm, especially on urban roads. However, due to the frequent wetness of the road surface and the overlap of vehicle loads, the service life is greatly reduced. The current waterproofing of the road surface is generally emulsified asphalt sealant. The waterproofing of the first layer, which only closes the original capillary pores of the asphalt pavement in a short period of time, has a waterproof effect, but with the driving wear of the emulsified asphalt film, the waterproof effect is getting worse and worse

Abstract

The invention relates to the technical field of road materials, in particular to a hydrophobic pavement coating material with good cohesiveness and toughness and a preparation method thereof. The hydrophobic pavement coating material is prepared by mixing a pavement binder and a hydrophobic modifier. The pavement binder is prepared by shearing a material A and a material B according to a weight ratio through a colloid mill. The material B is prepared by mixing hexadecyl trimethyl ammonium bromide, waterborne epoxy resin, cationic CR latex and water. The hydrophobic modifier is prepared by mixing nonylphenol polyoxyethylene ether, siloxane and water. The hydrophobic modifier is added into the pavement binder according to a weight ratio of 1: 10, and the hydrophobic modifier and the pavementbinder are uniformly stirred to obtain the hydrophobic pavement coating material. The hydrophobic pavement coating material is sprayed onto an original asphalt pavement, so that the asphalt pavementhas a hydrophobic effect, moisture is extruded out of capillary cracks of the original asphalt pavement and is gathered on the upper surface of the pavement in the form of water drops, and the purposes of preventing water invasion and prolonging the service life of the asphalt pavement can be achieved.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to a hydrophobic pavement coating material with good adhesion and toughness and a preparation method thereof. Background technique [0002] Due to the current requirements for air pollution control, road sprinkling has become the norm, especially on urban roads. However, due to the frequent wetness of the road surface and the overlap of vehicle loads, the service life is greatly reduced. The current waterproofing of the road surface is generally done by emulsified asphalt sealant. The waterproofing of the first layer only closes the original capillary pores of the asphalt pavement in a short period of time to achieve a waterproof effect, but with the driving wear of the emulsified asphalt film, the waterproof effect is getting worse and worse. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide...
