Asphalt mixture mineral powder, asphalt mixture mineral powder preparation method and application of oil shale to preparation of asphalt mixture mineral powder
The invention discloses an asphalt mixture mineral powder. The asphalt mixture mineral powder is prepared from the following raw materials in parts by weight: oil shale, limestone and an additive. Oil shale serves as mineral powder of an asphalt mixture for the first time, the binding force and the strength of mucilage formed between mineral powder and asphalt, as well as between mineral powder and the additive, the interspace of asphalt concrete is reduced, and relatively high dispersibility is realized. Key indexes such as the high-temperature rut resistance, the low-temperature cracking resistance and the water encroachment resistance of the asphalt mixture are improved, and the probability of 'looseness' of a traditional asphalt pavement is effectively reduced. Waste of oil shale resources is reduced, and the transport cost is lowered. The asphalt mixture mineral powder provided by the invention is simple in process, low in cost, high in performance and environment-friendly, and the invention also provides a production method of the asphalt mixture mineral powder.
