多年来,石灰、粉煤灰用作添加于天然细粒土或粘土中的稳定性材料越来越常见二灰土是用石灰和粉煤灰按一定比例与混合后的一种无机材料。本文主要研究二灰稳定土路用性能及施工工艺。二灰土是用石灰和粉煤灰按一定比例与混合后的一种无机材料。近二十年,特别在道路工程中的路基施工中,这主要是路基填料用量大,石灰和粉煤灰的材料来源比较广泛,而且价格低廉,施工简单,力学性能和水稳性好,成为土质改良的重要方法。我国公路部门在许多公路建设中(特别是高等级公路)都有用二灰稳定土。同时也应注意到由于二灰土路用性能所受因素比较多,也比较复杂。本文具体介绍二灰稳定土的路用性能与施工工艺的具体流程。同时研究了二灰稳定土在施工完成之后的养护问题及质量检测。 Over the years, the use of lime and fly ash as a stabilizing material in natural fine-grained soils or clays has become increasingly common. Lime-dust is an inorganic material that is mixed with lime and fly ash at a certain ratio. This paper mainly studies the lime-stabilized road performance and construction technology. Lime soil is lime and fly ash by a certain percentage of mixed with an inorganic material. In the recent two decades, especially in the subgrade construction of road works, the main reason is that the amount of subgrade filler is large, the sources of lime and fly ash are relatively wide, and the materials are cheap, the construction is simple, the mechanical properties and water stability are good, An important method of soil improvement. Our country highway department has the lime-stabilized soil in many highway construction (especially the high-grade highway). At the same time, it should also be noted that due to the characteristics of the road with more dirt, more complicated. This paper introduces the lime-stabilized soil road performance and construction process specific process. At the same time, the maintenance problems and quality testing of lime-flyash stabilized soil after construction are completed.
