小议二灰碎石混合料的标准及拌合控制措施

目前在我国高级公路的施工中,二灰碎石基层以其强度高、耐久性好,造价较低,易于施工等优点被广泛推广和应用,但随着这种半刚性基层的施工工艺的日益成熟和完善,各种具体施工中存在的问题和缺陷也逐渐暴露出来,甚至于通车不久的新路也出现了网裂、沉陷等路面破坏,本文将对二灰碎石基层施工过程中的原材料和拌和过程这两个重要环节进行探讨。

Discuss on the Standard of Lime-flyash-Macadam Mixture and Control Measure of Malaxation

At present,in the senior highway construction in China,the two gray gravel is widely promoted and applied for its advantages of high strength,durability,low cost,easy construction,but with the growing maturity and perfection of this semi-rigid base process,specific construction problems and defects have gradually exposed,even newly road networks have appeared split,road subsidence damage,so two important aspects of raw materials mixing process are discussed.
