针对上海当前二灰碎石基层施工技术现状 ,研究提高二灰碎石基层施工质量的关键技术和质量控制要点。扩展了现行规范方法中的参数抽样检验公式 ,使其适用于如二灰碎石基层顶面弯沉等呈对数正态分布参数的情况 Aiming at the current status of construction technology of lime-flyash gravel base in Shanghai, the key technologies and quality control points to improve the quality of lime-flyash gravel base construction are studied. Expanded the current standard method of parameter sampling test formula to make it suitable for such as lime-fly ash base surface deflection and other parameters were logarithmically normal distribution
