摘要
依托云湛高速公路新阳段对抗裂型水泥稳定碎石基层进行研究,通过室内试验研究了集料级配、灰剂量对无侧限抗压强度与干缩系数的影响,给出了主要筛孔通过率与灰剂量范围;最后通过现场检测对室内试验得出的结论进行了验证。
Based on studying anti-crack cement stabilized macadam base of Xinyang section of Yunzhan Expressway, this paper researched the influence of aggregate gradation and lime content on the unconfined compressive strength and shrinkage coefficient through laboratory test, and the through rate of main sieve pore and range of lime content were obtained. Finally, the conclusion from laboratory test was verified by field test.
