Modified asphalt and asphalt concrete
The invention relates to the field of high-molecular compounds, and particularly discloses modified asphalt and asphalt concrete.The modified asphalt is prepared from, by weight, 60-100 parts of matrix asphalt; 2-5 parts of a modifier; 0.2-1 part of a stabilizer and 6-8 parts of a temperature control agent; the temperature control agent comprises basalt powder, azobenzene, a styrene-acrylic emulsion and diethyl ether, and the weight ratio of the basalt powder to the azobenzene to the styrene-acrylic emulsion to the diethyl ether is 6: (3-7): 2: 1. The asphalt concrete comprises the following raw materials in parts by weight: 100-180 parts of coarse aggregate; 30 to 40 parts of river sand; 20 to 40 parts of modified asphalt; 2-10 parts of mineral powder; and 3-5 parts of boron nitride fiber. The method has the effect of improving the rutting resistance of the asphalt concrete pavement.
