Embodiment 1

[0027] Put 6-8 parts of 107 silicone rubber, 3-4 parts of hydrophobic fumed silica and 2-4 parts of hydrophobic barium sulfate into 100 parts of base asphalt at a temperature of 155-165°C, and stir at 600-800rpm for 20-30min ; 2. Put 0.03~0.05 parts of dibutyltin dilaurate, 0~0.02 parts of ethyl orthosilicate and 0.1~0.3 parts of γ-aminopropyltriethoxysilane into the asphalt at 155~165°C, with 300 Rotate at ~500rpm for 40~60min to obtain 107 silicone rubber modified asphalt; 3. Weigh 80~86 parts of ore aggregate, 4~6 parts of silicone modified asphalt, 4~10 parts of mineral powder 4. Heat the ore aggregate to 160-195°C, add 107 silicone rubber-modified asphalt at 155-165°C, mix for 90s, then add room temperature mineral powder and stir for 90s to obtain 107 silicone rubber-modified asphalt mixture material.

Embodiment 2

[0029] The best embodiment of this invention is:

[0030] Put 6 parts of 107 silicone rubber, 4 parts of hydrophobic fumed silica and 2 parts of hydrophobic barium sulfate into 100 parts of base asphalt at a temperature of 160 ° C, and rotate at 600 rpm for 30 minutes; 2. Put 0.03 parts of dibutyltin dilaurate, Put 0.01 part of ethyl orthosilicate and 0.3 part of γ-aminopropyltriethoxysilane into the asphalt at 160°C, and rotate it at 500rpm for 40min to obtain 107 silicone rubber modified asphalt; 3. Ratio by weight Weigh 86 parts of ore aggregate, 5 parts of silicone modified asphalt, and 9 parts of mineral powder; 4.

Abstract

The invention provides a bituminous concrete road surface material capable of reducing adhesion of snow ice on a bituminous road surface and a preparation method thereof, relating to bituminous road surfaces such as a freeway, a ramp, an overhead, a bridge surface and the like. The bituminous concrete road surface material comprises the following components: 107 organic silicon rubber modified bitumen, ore aggregate and ore powder. The preparation method comprises the following steps: firstly, preparing a 107 organic silicon rubber modified bitumen cement material; and then preparing an organic silicon rubber modified bituminous mixture. By utilizing a high hydrophobic bitumen film which is formed by organic silicon rubber with low surface energy on the surface of the aggregate and insidethe gap of the aggregate, the adhesion of the snow ice on the road surface is reduced, thus the snow ice is easy to eradicate.

Description

technical field [0001] The invention relates to an asphalt concrete pavement material for reducing ice and snow cohesion and a preparation method thereof, and relates to asphalt pavements such as highways, ramps, viaducts, and bridge decks. Background technique [0002] In winter, ice accumulation on asphalt concrete pavement is usually difficult to effectively remove, and traffic accidents caused by ice accumulation often lead to billions or even higher direct economic losses. In order to ensure traffic safety and avoid major accidents, during the ice disaster warning period, expressway management departments often take closed measures reluctantly, and the resulting losses are also very large. [0003] Common deicing methods include chemical deicing agents, mechanical deicing and thermal deicing. Chemical deicing methods use chemical active agents to lower the freezing point of road surface water to delay the crystallization of ice. Usually, there are alcohol deicing metho...
