摘要
针对南方地区湿热的气候条件和满足交通荷载大的两个特点,本文选取现行规范推荐级配范围和调整后的建议级配范围中的5条级配曲线开展了水泥稳定碎石矿料级配优化试验,尝试在满足交通荷载大需要强度大的情况下,确定需要水泥用量最小的最优级配,同时达到改善其干缩抗裂性能的目的。
Taking into account of two factors which include humid-hot climate and heavy traffic loads, this paper, studied optimising aggregate gradation for cement stabilized crushed stone. In order to improve the performance of anti premature cracking, the optimal gradation which satisfies high strength and low cement content from 5 gradations the recommended by the existing effective and modified specifications.
