Scope

Main technical content: By controlling the proportion of used asphalt mixtures, new asphalt, and new aggregates, it is conducive to better mixing of old and new asphalt, thus improving the compressive strength and fatigue resistance of the resulting recycled asphalt mixtures. This, in turn, helps to expand the application scope of recycled asphalt mixtures and better conserve resources, leading to improved economic benefits. By using N-methyl-1-[1-(2-thienylmethyl)-4-piperidinyl]methanamine, salicylic acid oxime, and o-nitro-dodecanol ether in synergy, it is conducive to better separation of old asphalt and old aggregates. At the same time, it helps to improve the compatibility of old asphalt, old aggregates, and new asphalt, new aggregates, making it easier to mix the resulting recycled asphalt mixtures evenly. This, in turn, helps to improve the compressive strength and fatigue resistance of the resulting recycled asphalt mixtures, thus expanding the application scope of recycled asphalt mixtures and better conserving resources, leading to improved economic benefits.
