High content regenerated mineral aggregate/asphalt mixture and preparation method thereof
The invention relates to a high content regenerated mineral aggregate/asphalt mixture and a preparation method thereof. Building solid waste residues and petroleum asphalt are adopted as main raw materials, Bacillus pasteurii is adopted as a biological modifier, a microbial chemical deposition product calcium carbonate generated by the Bacillus pasteurii is used as a physical filler and a chemical adhesive, and the performances of regenerated mineral aggregates are restored and enhanced by adopting a microbial chemical deposition technology. The mixture is a novel asphalt mixture with building industrial solid waste slag as main mineral aggregate, a green restoration technology is adopted, and the regenerated mineral aggregate is processed through a microbial technology to realize recycling of building solid waste slag with severe pollution, so the exploitation of raw materials is greatly reduced, the cost is low, and the regenerated mineral aggregate/asphalt mixture has excellent performances.
