Rubber asphalt concrete
The invention belongs to the technical field of compositions of mortar, concrete or artificial stone of asphalt materials, and discloses rubber asphalt concrete, which comprises rubber asphalt and graded stone, wherein the rubber asphalt comprises petroleum asphalt, rubber powder and an interface modifier; and the interface modifier comprises SBS, EVA, a rubber cross-linking agent and carbon black. The preparation method of the rubber asphalt concrete comprises the following steps: fully stirring and mixing the prepared rubber asphalt and graded stone in a high-temperature environment to formthe rubber asphalt concrete. The rubber asphalt concrete is prepared from the improved rubber asphalt, and the used rubber asphalt solves the problems of poor storage stability and unstable comprehensive pavement performance and poor performance caused by poor storage stability when the rubber asphalt is applied to an asphalt mixture in the prior art; the performance of the rubber asphalt concretecan be stable.
本发明属于沥青材料的砂浆、混凝土或人造石的组合物技术领域，公开了一种橡胶沥青混凝土，包括橡胶沥青和级配石料，橡胶沥青包括石油沥青、橡胶粉、界面改性剂；界面改性剂包括SBS、EVA、橡胶交联剂、炭黑。橡胶沥青混凝土的制备方法为将配置的橡胶沥青和级配石料在高温环境下充分的搅拌、混合，形成橡胶沥青混凝土。本发明应用改进后的橡胶沥青制备成橡胶沥青混凝土，使用的橡胶沥青解决了现有技术中存在的存储稳定性差及其带来的应用于沥青混合料时综合路用性能不稳定、性能不佳的问题；能够使得橡胶沥青混凝土的性能稳定。
