摘　　要：为了提升水泥稳定碎石混合料的耐久抗裂性能,基于颗粒流理论的水稳混合料新型拌合技术,改善混合料搅拌过程中集料均匀性,提高水泥稳定碎石混合料性能,并在满足强度指标前提下,进一步探究新型拌合工艺降低水泥剂量和缩短养护龄期的可行性。In order to improve the durability and crack resistance of cement-stabilized crushed stone mixture,a new mixing technology for water-stabilized mixture based on particle flow theory is proposed in this paper to improve the uniformity of aggregate during the mixing process,improve the performance of the mixture,and meet the strength index on the premise.The feasibility of reducing the cement dosage and shortening the curing age of the new mixing process was further explored.
