WARM-MIXED RUTTING RESISTANT ASPHALT MIXTURE AND PREPARATION METHOD THEREOF

摘要

Provided are a warm-mixed rutting resistant asphalt mixture and preparation method thereof, the warm-mixed rutting resistant asphalt mixture comprising a warm-mixed asphalt additive and a rutting resistant asphalt modifier; the warm-mixed asphalt additive is 2.5%-5% by weight of the asphalt mixture; and the rutting resistant asphalt modifier is 1%-6% by weight of the asphalt mixture. The asphalt mixture of the present invention has obvious warm-mixing effect, reduces the mixing temperature by 30℃ or more, reduces the paving temperature, dramatically improves the rutting resistance and the cracking resistance of the asphalt mixture under low temperatures, and is cost-effective.
