▎ 摘  要

NOVELTY - Low-temperature and anti-cracking asphalt mixture, comprises 20-40 pts. wt. modified asphalt, 8-10 pts. wt. gravel, 5-7 pts. wt. natural sand, 0.3-0.5 pts. wt. polyester fiber, 10-20 pts. wt. coal gangue powder, 1-3 pts. wt. tributyl citrate, 0.3-0.5 pts. wt. alkyl alcohol amide, 0 1-0 3 pts. wt. hydrogenated naphtha, 0 0-0 0.07 pts. wt. fatty acid methyl ester and 4-6 pts. wt. mineral powder, where the modified asphalt is obtained by modifying styrene-butadiene block copolymer. USE - The low-temperature and anti-cracking asphalt mixture is useful in the field of asphalt material. ADVANTAGE - The mixture: is safe; has excellent durability, stability, low temperature crack resistance and low temperature bending damage strain and freeze-thaw splitting tensile strength ratio. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the low-temperature and anti-cracking asphalt mixture, comprising heating the modified asphalt to 170-180℃, adding the remaining raw materials of the asphalt mixture, and uniformly stirring to obtain the final product.
