全深式就地冷再生是对废旧面层基层材料的有效使用,本文对现场铣刨料筛分进行级配分析,确定了RAP旧料和RBP旧料的最佳比例为70:30,在RAP/RBP的最佳比值基础上,针对不同水泥剂量成型试件,结合无侧限抗压强度、劈裂强度、和抗压回弹模量等力学指标,确定了稳定剂水泥的最佳剂量为6%,并总结出各力学指标之间的相互关系,希望通过全深式水泥就地冷再生的主要影响因素研究,对全深式就地冷再生施工提供一定意义的参考。
Full-depth on-site cold regeneration is the effective use of waste surface layer of grass-roots materials, this article on-site milling planing screening grading analysis to determine the RAP old material and RBP old material the best ratio of 70:30, at RAP / RBP based on the optimal ratio, for different cement dose forming specimens, combined with unconfined compressive strength, splitting strength, and compressive resilience modulus and other mechanical indicators to determine the optimal dosage of stabilizer cement 6%, and summed up the relationship between the various mechanical indicators, hope all-depth in-situ cement deep cold regeneration of the main factors that affect the full-depth on-site cold regeneration construction to provide some reference.
