Cold-mixed and cold-laid composite asphalt mixture and preparation method thereof
The invention relates to the field of asphalt mixtures, and particularly discloses a cold-mixed and cold-laid composite asphalt mixture and a preparation method thereof. The asphalt mixture comprises the following components in parts by weight: 1-6 parts of emulsified asphalt; 35 to 95 parts of RAP; 0.42 to 1.14 parts of a regenerant; 10 to 50 parts of aggregate; 1-5 parts of cement; 2-20 parts of mineral powder; 1 to 10 parts of water; 0.01 to 0.1 part of an additive; wherein the regenerant comprises base oil, a plasticizer and an anti-aging agent in a weight ratio of (75-85): (18-22): (3-5). The mixing effect of the RAP, the matrix asphalt and other components in the asphalt mixture is good, even if the addition amount of the RAP is large, the asphalt mixture can still have good pavement performance, waste resources are utilized to a great extent, more environment-friendly raw materials are used as much as possible, and the sustainable development concept is met.
本申请涉及沥青混合料领域，具体公开了一种冷拌冷铺式复合型沥青混合料及其制备方法。该沥青混合料包括以下重量份的组分：乳化沥青1‑6份；RAP 35‑95份；再生剂0.42‑1.14份；集料10‑50份；水泥1‑5份；矿粉2‑20份；水1‑10份；外掺剂0.01‑0.1份；其中，所述再生剂包括重量比为（75‑85）:（18‑22）:（3‑5）的基础油、增塑剂和抗老化剂。本申请的沥青混合料中RAP和基质沥青等其他组分混合效果良好，即使在RAP添加量较大的情况下，仍能具有较佳的路用性能，并且极大程度的利用了废旧资源，并尽可能的使用更为环保的原料，符合可持续发展理念。
