改性沥青水泥混凝土应用探讨

通过制做超早强免振自密实混凝土,分析混凝土刚度高的原因,找出改进途径并从几项路用性能指标分析复合材料微观结构的合理性分析,最后通过大量的试验和数据来验证粗集料外表面包裹改性沥青再拌和水泥砂浆形成的改性沥青水泥混凝土用于高等级公路半刚性基层局部破损快速修补上相对于典型半刚性基层材料的优越性。

An Approach to Application of Cement Concrete of Modified Asphalt

By way of manufacturing the concrete of premature strength,nonoscillating and self-density,the paper analyzes reasons for concrete high rigidity,finds the way to improvement and analyses rationality of microcosmic structure of composite materials,lastly,by large numbers of experiments and experimental data verifies the superiority of cement concrete of modified asphalt which the coarse aggregate's outside surface contains the modified asphalt and the cement motar fixed to the typical materials for semi-rigid base in the rapid mend of partial damage when the are applied to the high-type highway's semi-rigid base.
