Organic composite warm asphalt mixture and preparation method thereof
The invention discloses an organic composite warm asphalt mixture. The mixture is prepared from 4-6wt% of asphalt, 90-92wt% of aggregate, 1-2wt% of ore powder, 1-2wt% of an inorganic filler and 0.1-0.2wt% of an organic composite warm mixing agent, wherein the organic composite warm mixing agent comprises one or more of ethylene bisstearamide, octadecanamide, oleamide and ethylene bisoleamide. The organic composite warm asphalt mixture substantially reduces the mixing and compacting temperature of the warm asphalt mixture, greatly saves energy, reduces the discharge of waste gas, effectively guarantees that the high temperature, the water stability and other pavement performance indexes of the warm asphalt mixture approach or are better than those of routine asphalt mixtures, and meets practical engineering standard requirements. The organic composite warm asphalt mixture disclosed in the invention has the characteristics of few components, simple preparation technology and low cost. The invention also provides a preparation method of the organic composite warm asphalt mixture.
