Construction process of pouring type composite concrete pavement
The invention discloses a cast-in-place composite concrete pavement construction technology, and belongs to the technical field of asphalt concrete pavement construction, and the cast-in-place composite concrete pavement technology is characterized in that an open-graded large-void (VV: 18-25%) special asphalt mixture is used as a matrix, and a specially-made high-performance cement-based grouting material is poured to fill internal voids of the matrix; according to the novel pavement structure, a flexible framework with stress relaxation capability and a rigid network structure which is not influenced by high temperature are integrated, so that the advantage of high low-temperature deformation capability of an asphalt material is fully exerted, and meanwhile, high-temperature strength and deformation resistance are provided through a cement-based material; the concrete pavement has the characteristics of high strength, early strength, crack resistance, skid resistance, oil corrosion resistance and the like, and a specific implementation process is provided to solve the problem that the design of a cast-in-place composite concrete pavement is not comprehensive and unreasonable.
本发明公开了灌注式复合混凝土路面施工工艺，属于沥青混凝土路面施工技术领域，灌注式复合混凝土路面技术是以开级配大空隙(VV：18～25％)特种沥青混合料为基体，灌入特制的高性能水泥基灌浆材料填充其内部空隙，而形成的一种“刚柔并济”的新型路面结构，具有应力松弛能力的柔性骨架和不受高温影响的刚性网络结构为一体，使之充分发挥沥青材料低温变形能力强的优势，同时通过水泥基材料提供高温强度和抗变形能力，具有高强、早强、抗裂、防滑、耐油蚀等特性，并提供了具体的实施工艺填补了灌注式复合混凝土路面的设计不全面不合理的问题。
