冷拌冷铺沥青混合料研究现状与发展

Research Status and Development of Cold Mix and Cold Paving Asphalt Mixture

为进一步推广冷拌冷铺技术的工程应用,论文在综合国内外研究现状的基础上,根据胶结料不同分别论述了乳化型、溶剂型、反应型三种冷拌冷铺沥青混合料的强度形成机理,从混合料拌和、摊铺、碾压的角度总结了冷拌冷铺沥青混合料施工工艺,结合冷拌冷铺沥青混合料材料特性,分析了其社会及环境效益,针对冷拌冷铺技术现状从混合料配合比设计方法、性能评价体系、耐久性提升方面提出了冷拌冷铺沥青混合料进一步研究建议,对于冷拌冷铺技术的推广应用具有积极地推动作用。

In order to further promote the application of cold mix cold paving technology, based on the com-prehensive research status at home and abroad, the paper analyzes the strength formation mech-anism of three cold mixed cold pave asphalt mixtures, namely emulsification, solvent and reaction, according to the different cementation materials. The construction technology of cold mixed cold asphalt mixture is summarized from the perspective of mixture mixing, spreading and rolling, and combined with cold mixed cold asphalt. The paper analyzes the social and environmental benefits of the green mixture material. According to the current situation of cold mix cold paving technology, the further research suggestions on the mix ratio design method, performance evaluation system and durability improvement are put forward, which will promote the promotion and application of cold mix cold paving technology.
