The invention discloses a direct vat set asphalt concrete high-viscosity and high-elasticity modifier which comprises the following components in parts by weight: 20-30 parts of thermoplastic rubber (SEBS), 40-60 parts of industrial grade white oil, 15-25 parts of polyethylene, 1-3 parts of stearic acid, 0.5-1.5 parts of carboxylic acid, 0.1-0.3 part of peroxide initiator and 0.5-1.5 parts of color master batch, and also discloses a preparation method and a use method of the direct vat set asphalt concrete high-viscosity and high-elasticity modifier. The invention belongs to the technical field of asphalt concrete modifiers, and particularly provides a direct vat set asphalt concrete high-viscosity and high-elasticity modifier and a preparation and use method thereof, the modifier has the characteristic of high viscoelasticity, on one hand, direct vat set addition can be achieved, and on the other hand, the modifier has the high-viscosity and high-elasticity performance; compared with the traditional SBS modifier, the process of processing modified asphalt is saved, the development time is saved, and the production efficiency of the asphalt mixture is improved; on the other hand, matrix asphalt can be added through a wet method, and the requirement for preparing and producing high-viscosity and high-elasticity modified asphalt can be met.
本发明公开了直投式沥青混凝土高粘高弹改性剂，包括下列重量份数的组分：热塑性橡胶(SEBS)20‑30份，工业级白油40‑60份，聚乙烯15‑25份，硬脂酸1‑3份，羧酸0.5‑1.5份，过氧化物引发剂0.1‑0.3份，色母粒0.5‑1.5份，同时还公开了其制备方法和使用方法。本发明属于沥青混凝土改性剂技术领域，具体提供了一种直投式沥青混凝土高粘高弹改性剂及其制备和使用方法，该改性剂具有高粘弹性特点，一方面该外加剂可实现直投式添加，较传统SBS改性剂节省了加工改性沥青的工序同事节省了发育时间，提高沥青混合料生产效率；另一方面，也可通过湿法添加入基质沥青，可实现制备生产高粘高弹改性沥青的需求。
