Abstract

The invention relates to the field of asphalt pavement material preparation, and discloses a salt particle used for the micro-surface of asphalt pavement and a preparation method thereof. The salt compound particles include the following raw material components: salt compound powder, bisphenol A type epoxy resin, polyamine curing agent, aromatic hydrocarbon oil, polyolefin and layered silicate; its preparation method is: firstly mix the above The raw material components of the salt particles are put into the mixing barrel, mixed, heated, and stirred to form a uniform plastic mass, and then the plastic mass is sequentially cured, extruded, granulated, cut, and finally cured, that is have to. The salt particles can not only be used in asphalt pavement maintenance projects, but also can realize the self-melting function of asphalt pavement, which has important practical significance and engineering application value.

Description

technical field

[0001] The invention relates to the field of asphalt pavement material preparation, in particular to a salt particle used for the micro-surface of asphalt pavement and a preparation method thereof. Background technique

[0002] In most parts of northern my country, the southwestern plateau, and the central mountainous area, snowfall and freezing weather often occur in winter. As the road area snow freezes, the adhesion coefficient and friction coefficient between car tires and the road surface are greatly reduced, resulting in tire slippage and extended braking distances. , In severe cases, it will cause sideslip, loss of direction control, rollover, and even cause serious traffic accidents.

[0003] At present, in order to ensure driving safety and smooth roads, there are mainly active snow removal technology and passive snow removal technology at home and abroad to clear road snow and icing. Among them, the passive snow removal technology mainly includes ma...
