Emulsifier type cold-mixed and cold-laid asphalt mixture and preparation method thereof
The invention discloses an emulsifier type cold-mixed and cold-laid asphalt mixture and a preparation method thereof, and the emulsifier type cold-mixed and cold-laid asphalt mixture comprises the following components in parts by mass: 400-600 parts of coarse aggregate, 400-600 parts of fine aggregate, 90-160 parts of modified emulsified asphalt, 10-30 parts of mineral filler and 2-8 parts of water reaction type resin demulsifier, wherein the molecular weight of the water reaction type resin demulsifier is 1 to 10 million. According to the emulsifier type cold-mixed and cold-laid asphalt mixture provided by the scheme, on the premise that cement is not used and the pavement performance of the asphalt mixture is guaranteed, the forming speed of the early strength of the asphalt mixture is increased, and the technical problem that in the prior art, a pavement laid by the asphalt mixture added with cement is difficult to recycle is solved; the defects in the prior art are overcome.
本发明公开了一种乳化剂型冷拌冷铺沥青混合料及其制备方法，其中，按照质量份数，包括粗集料400～600份、细集料400～600份、改性乳化沥青90～160份、矿质填料10～30份和水反应型树脂类破乳剂2～8份；其中，所述水反应型树脂类破乳剂的分子量为100～1000万。本方案提出的一种乳化剂型冷拌冷铺沥青混合料，在不使用水泥和保证其路用性能的前提下，加快沥青混合料早期强度形成的速度，并解决现有技术中添加有水泥的沥青混合料铺设的路面回收困难的技术问题，以克服现有技术中的不足之处。
