二灰碎石水泥就地冷再生基层应用探讨

Application of Lime-flyash-Stabilized Cement Base In-situ Cold Reuse Technology

二灰碎石水泥就地冷再生是对原有二灰碎石基层充分利用,二灰碎石水泥就地冷再生有自身的工程特点,从现场铣刨料的级配、最大干密度和最佳含水量的确定、7d无侧限强度以及施工工艺等方面详细介绍二灰碎石水泥就地冷再生过程,通过本工程二灰碎石水泥就地冷再生成功应用,对水泥就地冷再生施工有一定的参考意义。

In-situ cold reclamation of lime-flyash cement is the best approach to using original lime-flyash stabilized base. Cold ash lime-flyash cement has it special engineering characteristics. This paper introduced the detailed process of the cold reclamation process of lime-flyash cement,including selection of aggregate, the determination of density and optimum water content, seven-day unconfined strength experiments and construction technics, etc. This successful application of cold recycling construction provided a good reference for similar projects.
