Abstract

The invention discloses an environment-friendly recycled asphalt mixture and a preparation technology thereof. The environment-friendly recycled asphalt mixture comprises waste asphalt, biological asphalt, modified asphalt, 40-mesh waste tire powder, aggregate, mineral powder, environment-friendly solvent oil, mandarin oil, coumarone, smectite, silver-loaded zeolite, lime, stannic oxide, 3-isocyanatopropyltriethoxysilane, polyoxyethylene ether, glycerophosphate, a recycling agent and sodium silicate. The environment-friendly recycled asphalt mixture has the advantages that the recycled asphalt mixture with all pavement properties ranking as a high level is capable of ameliorating tension in supply of petroleum asphalt, is environment friendly and energy saving by using the wastes reasonably and can be used as a novel substitute of petroleum asphalt mixtures.

Description

technical field [0001] The invention belongs to the technical field of asphalt, and in particular relates to an environmentally friendly recycled asphalt mixture and a preparation process thereof. Background technique [0002] As the use of automobiles in our country increases year by year, the number of waste tires scrapped every year reaches hundreds of millions, and the weight exceeds tens of millions of tons, which brings a heavy burden to environmental governance. Therefore, rational use of scrap tires has become an effective solution. measure. In the field of road construction, the number of asphalt pavements that need to be repaired in our country increases year by year. If a large amount of excavated and milled asphalt mixture is discarded, it will not only cause waste of resources, but also seriously pollute the environment. In addition, mining new stone when preparing asphalt pavement will also seriously damage the ecological environment. In addition, with the sh...
