<p>PURPOSE: Warm asphalt concrete containing waste white clay is provided to give a mesophilic property to asphalt using the waste white clay without using a wax-based additive. CONSTITUTION: Warm asphalt concrete containing waste white clay comprises 4-12 parts by weight of asphalt and waste white clay containing moisture in 100.0 of aggregate. The moisture-containing waste white clay is contained at an amount that is 3-30% of the weight of the asphalt. The moisture-containing waste white clay has a water content of 10-30%. The waste white clay is disused after purifying vegetable oil. The aggregate comprises a waste asphalt concrete recycled aggregate and a general aggregate at a weight ratio of 10:90-80:20. The aggregate is comprised of 45-85 wt% of coarse aggregate, 10-45 wt% of fine aggregate, and 5-10 wt% of filler and thus has flow resistance. The aggregate is comprised of 60-73 wt% of coarse aggregate, 25-35 wt% of fine aggregate, and 2-5 wt% of fillers and thus has low-noise flow resistance. The aggregate is comprised of 70-90 wt% of coarse aggregate, 7-27 wt% of fine aggregate, and 3-8 wt% of fillers and thus has drainage and permeability.</p> |
