二灰稳定碎石基层比水泥稳定碎石造价低、易于施工,具有良好的力学性能、板体性、水稳性和抗冻性,干缩、冷缩造成的裂缝又不及水泥稳定碎石明显,所以交通量不大的次高等级公路和一些市政工程中还普遍应用。如何提高二灰稳定碎石基层的强度,一直是同行们面临的课题。本文分别从原材料、配合比、拌和、摊铺、养生等各个方面对影响二灰稳定碎石混合料强度的要素进行了研究分析。
The lime-lime stabilized macadam base is lower cost than cement stabilized macadam, easy to be constructed, has good mechanical properties, plate body, water stability and frost resistance, and cracks caused by shrinkage and shrinkage are not as obvious as cement stabilized macadam , So traffic is not large secondary highways and some municipal engineering is also widely used. How to improve the strength of the lime-lime stabilized gravel has always been a subject for our colleagues. In this paper, the factors influencing the strength of lime-flyash stabilized aggregate are studied and analyzed from the aspects of raw materials, mixing ratio, mixing, paving, health preservation and so on.
