摘要
近年来我国公路修筑技术有了很大提升,然而随着现行行业标准技术规范、质量标准的日益完善,对路面基层的施工工艺及质量控制也提出了较高的要求。目前在我国高等级公路的施工中,二灰碎石基层是普遍采用的一种结构形式。二灰碎石基层属于半刚性路面,因其具有良好的力学性能、整体性能以及承载力高、耐久性好、强度高、造价较低、材料易选、易于施工等优点被广泛应用。鉴于此,对二灰碎石基层施工中应注意的问题及其质量控制措施进行了探讨,以供参考。
In recent years, China's highway construction technology has been greatly improved, but with the improving of the current industry standard, technical specifications and quality standards, higher requirements are also put forward on construction technology and quality control of pavement base. Currently in the construction of high-grade highway in China, the lime-fly ash gravel base is a structure commonly used. linne-fly ash gravel base belongs to semi-rigid pavement. Because of its good mechanical properties, overall performance, high capacity, durability, high strength, low cost, easy to choose the material, easy construction and other advantages, it is widely used. Given this, the paper discusses some problems should be paid attention to and related control measures in lime-fly ash gravel construction.
