超厚宽幅水泥稳定碎石基层由于一次性宽幅施工,具有整体性强、裂缝少、降低工程造价等优良性能。结合瓜星高速公路超厚宽幅水稳碎石基层试验路段,从原材料、室内成型方式、配合比等方面,对超厚宽幅水稳碎石基层一次性施工关键技术进行研究,为超厚宽幅水泥稳定碎石基层一次性施工的推广及应用提供了理论依据和施工经验。 Due to the one-time wide construction, the super-thick and wide cement stabilized macadam base has the advantages of strong integrity, less cracks and lower construction cost. Combined with the experimental section of Guishu Expressway with thick and thick water-stabilized gravel base, the key technologies of one-time construction of super-thick and wide water-stabilized gravel base were studied from the aspects of raw materials, indoor forming methods and compounding ratio, This paper provides a theoretical basis and construction experience for the promotion and application of one-time construction of wide-scale cement stabilized macadam base.
