Rubber asphalt, low-carbon rubber foamed asphalt, rubber asphalt mixture and preparation method thereof
The invention provides rubber asphalt, low-carbon rubber foamed asphalt, a rubber asphalt mixture and a preparation method thereof. The rubber asphalt comprises the following components: surface-treated rubber powder, a polymer modifier and an asphalt matrix, wherein the rubber powder subjected to surface treatment is rubber powder subjected to surface treatment by carbon tetrachloride and/or an alkaline agent. The rubber asphalt provided by the invention has low surface free energy, and the wettability and adhesiveness after foaming are improved. The rubber asphalt mixture disclosed by the invention can be used for greatly reducing the emission of toxic gas, so that the influence of rubber asphalt pavement construction on the surrounding environment and construction operators is reduced. Meanwhile, influence on the environment and the health of constructors are extremely reduced, and the environmental protection benefit is very remarkable.
本发明提供一种橡胶沥青、低碳橡胶发泡沥青、橡胶沥青混合料及其制备方法。所述橡胶沥青包括以下组成：表面处理的橡胶粉，聚合物改性剂，以及沥青基质；其中，所述表面处理的橡胶粉为经四氯化碳和/或碱剂表面处理的橡胶粉。本发明的橡胶沥青具有较低的表面自由能，发泡后的润湿能力和黏附性均有所改善。本发明的橡胶沥青混合料能够实现有毒气体排放的大幅降低，从而减小橡胶沥青路面施工对周围环境以及施工作业人员的影响。对环境的影响以及施工人员的健康极为有利，环境保护效益十分显著。
