High-rut-resistance large-proportion recycled asphalt mixture and preparation method thereof
The invention relates to the field of asphalt mixtures, and particularly discloses a high-rut-resistance large-proportion recycled asphalt mixture and a preparation method thereof. The high-rut-resistance large-proportion recycled asphalt mixture is prepared from the following components in parts by weight: 29-48 parts of limestone, 1-2 parts of a filler, 50-70 parts of an old material, 1.4-2.8 parts of warm mix asphalt, 0.05-0.15 part of a modified regenerant and 0.3-0.5 part of an anti-rutting agent; the modified regenerant comprises base oil, a ductility improver and tackifying resin, and the weight ratio of the base oil to the ductility improver to the tackifying resin is 1: (0.08-0.1): (0.02-0.04); and the warm mix asphalt comprises asphalt and a warm mix agent in a weight ratio of 1:(0.1-0.12). The high-rutting-resistance large-proportion recycled asphalt mixture has the advantages that the utilization rate of old materials can be increased, and the rutting resistance of the recycled asphalt mixture is improved.
本申请涉及沥青混合料领域，具体公开了一种高抗车辙性大比例再生沥青混合料及其制备方法。一种高抗车辙性大比例再生沥青混合料按重量份计，包括以下组分：石灰岩29‑48份，填料1‑2份，旧料50‑70份，温拌沥青1.4‑2.8份，改性再生剂0.05‑0.15份，抗车辙剂0.3‑0.5份；其中，改性再生剂包括基础油、增延剂和增粘树脂，其中基础油、增延剂和增粘树脂的重量比为1：（0.08‑0.1）：（0.02‑0.04）；温拌沥青包括重量比为1:（0.1‑0.12）的沥青和温拌剂。本申请的一种高抗车辙性大比例再生沥青混合料具有能够提升旧料利用率、提升再生沥青混合料的抗车辙性的优点。
