Asphalt production process based on asphalt pavement old material thermal regeneration
The invention relates to the technical field of asphalt, and particularly discloses an asphalt production process based on asphalt pavement old material thermal regeneration. The production process comprises the following steps: S1, crushing and screening an old asphalt pavement material to obtain a crushed old asphalt pavement material; s2, the crushed old asphalt pavement material is soaked in a sulfuric acid solution with the mass concentration of 5%-10%, filter residues are washed and dried after filtration, and an old acidified asphalt pavement material is obtained; s3, heating, melting and acidizing the old asphalt pavement material, adding a regenerant, and stirring to obtain a hot old asphalt pavement material; and S4, adding the new aggregate, the powder and the new asphalt into the asphalt pavement hot old material, and stirring to obtain the hot recycled asphalt. In the production process, the contact rate and the contact area between the old asphalt and the regenerant and between the old asphalt and the new asphalt can be effectively increased, so that the fusion effect of the old asphalt and the new asphalt and the regeneration effect of the old pavement asphalt are improved.
本申请涉及沥青技术领域，具体公开了一种基于沥青路面旧料热再生的沥青的生产工艺。该生产工艺包括以下步骤：S1：粉碎筛分沥青路面旧料，得到粉碎后的沥青路面旧料；S2：将粉碎后的沥青路面旧料浸泡在质量浓度为5%～10%的硫酸溶液中，过滤后将滤渣洗涤烘干，得到酸化沥青路面旧料；S3：加热熔融酸化沥青路面旧料，加入再生剂搅拌，得到沥青路面热旧料；S4：在沥青路面热旧料中加入新集料、粉料、新沥青，搅拌后得到热再生沥青。本申请在生产过程中可以有效提高旧沥青与再生剂、新沥青的接触率和接触面积，从而有助于提高沥青旧料与新沥青的融合效果和路面沥青旧料的再生效果。
