Regeneration method of asphalt mixture
The invention discloses an asphalt mixture regeneration method which specifically comprises the following steps: S1, crushing waste materials: crushing a waste asphalt mixture, and enabling the maximum particle size of the crushed waste asphalt mixture to be smaller than 31.5 mm; s2, feeding and stirring for the first time: adding emulsified asphalt, a regenerant and a solubilizer into the crushed waste asphalt mixture, and stirring for 15-25 minutes at the stirring speed of 100-150r/min; s3, adding materials and stirring for the second time: adding an emulsifier and latex, and stirring for 15-25 minutes at the stirring speed of 100-150r/min; s4, adding and stirring for the third time: adding the cement and the water, and stirring for 30-40 minutes at the stirring speed of 150-200 r/min; s5, feeding and stirring for the fourth time: adding a new asphalt mixture, and stirring for 60-120 minutes at the stirring speed of 200-300 r/min; the reclaimed material of the asphalt mixture obtained by the invention has physicochemical properties similar to those of a new asphalt mixture, can replace the new asphalt mixture, greatly reduces the use amount of the new asphalt mixture, and has the advantages of energy conservation and environmental protection.
本发明公开了一种沥青混合料的再生方法，具体包括以下步骤：S1、破碎旧料：对废旧的沥青混合料进行破碎，破碎后废旧沥青混合料的最大粒径要小于31.5mm；S2、第一次加料搅拌：将破碎后的废旧沥青混合料中加入乳化沥青、再生剂和增溶剂，搅拌15‑25min，搅拌速度为100‑150r/min；S3、第二次加料搅拌：加入乳化剂和胶乳，搅拌15‑25min，搅拌速度为100‑150r/min；S4、第三次加料搅拌：加入水泥和水，搅拌30‑40min，搅拌速度为150‑200r/min；S5、第四次加料搅拌：加入新制沥青混合料，搅拌60‑120min，搅拌速度为200‑300r/min；通过本发明得到的沥青混合料的再生料具有与新制沥青混合料相近的理化性质，可替代新制沥青混合料使用，极大的降低了沥青混合料新料的使用量，具有节能环保的优点。
