| titleOfInvention |
Asphalt concrete and preparation method thereof |
| abstract |
The invention belongs to the technical field of building materials, and particularly relates to asphalt concrete and a preparation method thereof. The product developed by the invention comprises the following raw materials in parts by weight: 60-80 parts of emulsified asphalt, 50-60 parts of concrete slurry and 100-200 parts of coarse aggregate; the emulsified asphalt comprises the following raw materials in parts by weight: 800 portions of 600-800 portions of oxidized asphalt, 120 portions of crosslinked sodium polyacrylate, 30-50 portions of emulsifier, 8-10 portions of stabilizer and 1000 portions of 800-1000 portions of water; the concrete slurry comprises the following raw materials in parts by weight: 80-100 parts of cement, 70-90 parts of water, 3-5 parts of a polycarboxylic acid water reducing agent and 4-10 parts of polypropylene fiber. In addition, the modified nano silicon dioxide with the mass of 5-10% of the emulsified asphalt is also included; the modified nano silicon dioxide is nano silicon dioxide with vinyl functional groups grafted on the surface. Wherein the polypropylene fibers are staple fibers; the short fiber has the length of 300-600 mu m and the length-diameter ratio of 5: 1-10: 1 in the fiber bundle. The product obtained by the invention has excellent water resistance. |
