Asphalt mixture warm mixing agent for hot in-place recycling and preparation method of asphalt mixture warm mixing agent
The invention discloses an asphalt mixture warm mixing agent for hot in-place recycling and a preparation method of the asphalt mixture warm mixing agent, and belongs to the technical field of composites.The asphalt mixture warm mixing agent is prepared from a polymer, bio-based grease and a water-containing carrier, the raw materials comprise the following components in parts by mass: 30-40 parts of a polymer, 10-30 parts of bio-based grease and 30-60 parts of a water-containing carrier, the water-containing carrier is one of an organic crystal water compound, an inorganic crystal water compound or water-absorbent resin; the polymer is one or a mixture of two of low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), ethylene-vinyl acetate copolymer (EVA) or polyolefin elastomer (POE). The problems that in the prior art, a dry method and a wet method of adding a warm mixing agent have respective problems, and no special warm mixing material for a geothermal regeneration construction process exists, so that the dynamic stability is poor, the water loss rate is not easy to control, the reinforcing effect is poor and the compatibility is poor are solved.
本发明公开了一种就地热再生用沥青混合料温拌剂及其制备方法，属于复合材料技术领域，原料包括聚合物、生物基油脂和含水载体，其中，以聚合物为基材；原料按质量比包括以下组分：聚合物30‑40份，生物基油脂10‑30份、含水载体30‑60份；含水载体为有机结晶水化合物、无机结晶水化合物或吸水树脂中的一种；聚合物为低密度聚乙烯(LDPE)，线性低密度聚乙烯(LLDPE)，高密度聚乙烯(HDPE)，乙烯‑醋酸乙烯共聚物(EVA)或者聚烯烃弹性体(POE)中的一种或两种的混合物。解决了现有技术中加入温拌剂的干法和湿法都存在各自的问题，也没有专门的用于地热再生施工工艺的温拌材料而导致的动稳定度差、失水率不易控制、补强效果差和相容性差的问题。
