Antibacterial asphalt concrete and preparation method thereof
The invention relates to antibacterial asphalt concrete and a preparation method thereof. The antibacterial asphalt concrete is prepared from the following raw materials in parts by weight: 5.5-11 parts of asphalt, 38-50 parts of quartz sand, 95-165 parts of coarse aggregate, 3.5-7 parts of mineral powder and 0.015-0.054 part of an antibacterial agent. The artificial coarse aggregate is adopted to replace part of the natural coarse aggregate, so that the light receiving area of the antibacterial agent is remarkably increased while the natural coarse aggregate is saved; and the antibacterial agent is respectively dispersed on the surface of the coarse aggregate, in the mineral powder and in the asphalt, so that the dispersity of the antibacterial agent in the asphalt concrete is improved, the exposure quantity of reaction active sites is ensured, and the purpose of effectively resisting bacteria is achieved.
本发明涉及一种抗菌沥青混凝土及其制备方法，所述抗菌沥青混凝土按重量份的原料配比为：沥青5.5~11份、石英砂38~50份、粗骨料95~165份、矿粉3.5~7份、抗菌剂0.015~0.054份。本发明采用人工粗骨料替代部分天然粗骨料，在节省天然粗骨料的同时，显著提升抗菌剂的受光面积；将抗菌剂分别分散在粗骨料表面、矿粉和沥青中，提高抗菌剂在沥青混凝土中的分散性，保证反应活性位点的暴露数量，达到有效抗菌的目的。
