Description

Technical Field

At present, anti-rutting modified asphalt concrete is made by adding anti-rutting agents during the asphalt production process. These particles are thermoformed during the rolling process, which is equivalent to filling the gaps in the aggregate skeleton with fine aggregates of a single particle size with high adhesion, increasing the skeleton effect of the asphalt mixture structure, strengthening the interaction between the mixtures, making the mixtures tighter, reducing the permeability of the formed pavement, and at the same time increasing the load-bearing capacity of the asphalt mixture; the existing preparation device for anti-rutting modified asphalt concrete is prone to produce harmful gases when stirring and mixing the modified asphalt concrete, thereby polluting the environment.

[0004] The above-mentioned device for preparing rutting-resistant modified asphalt concrete purifies toxic gases by mixing purification liquid with toxic gases. The purity of the purification liquid will decrease after long-term use, which will reduce the purification effect of the toxic gases and require replacement of the purification liquid. During the replacement of the purification liquid, the transportation of the toxic gases needs to be stopped to prevent the toxic gases from being directly discharged without the purification liquid, thereby reducing the work efficiency.
