Mixing production process for asphalt material used for asphalt pavement paving
The invention discloses a mixing production process for an asphalt material used for asphalt pavement paving. The production process comprises the following steps: S1, heating 40 parts by weight of asphalt to 120-220 DEG C, adding 10 parts by weight of a reactive solvent, conducting stirring at a first stirring speed of 30-60 rpm for 5 min, and continuing stirring at a second stirring speed of 80-140 rpm for 10 min to obtain a mixed solution; S2, adding 15 parts by weight of rubber into the mixed solution, and carrying out dispersing to obtain a suspended matter; S3, adding 10 parts by weightof epoxy resin into the suspended matter, and conducting stirring to obtain asphalt liquid; and S4, determining the particle size distribution of the curing agent according to the gradation and type of selected aggregate, and mixing the aggregate, 1 part of fibers and the asphalt liquid to obtain a normal-temperature asphalt mixture. According to the mixing production process, forming strength canbe improved, and pavement quality can be improved.
本发明公开了沥青路面铺设的沥青物料混合生产流程，包括以下步骤：S1：将40重量份沥青加热至120‑220℃，再加入10重量份反应型溶剂，在30‑60转/分钟的第一搅拌速度下搅拌5min，然后在80‑140转/分钟的第二搅拌速度下继续搅拌10min，得到混合液；S2：向所述混合液中加入15重量份橡胶，并分散得到悬浮物；S3：向所述悬浮物中加入10重量份环氧树脂，并搅拌得到沥青液；S4：根据所选集料的级配和类型确定固化剂的粒径分布，将所述集料、1份纤维与沥青液混合，得到常温沥青混合料。该沥青路面铺设的沥青物料混合生产流程，不仅能够提高成型强度，而且能够提高路面质量。
