    摘要：从海绵城市的目标出发，结合道路工程的特点，提出了基于基层的海绵型道路结构。该结构可以增强道路渗水、蓄水、排水的能力，进而削减峰值流量，降低内涝风险。以JTG D50—2006《公路沥青路面设计规范》中骨架密实型水泥稳定碎石级配为基础，进行了海绵型水泥稳定碎石基层的研究，分析不同粒径碎石对有效孔隙率和7 d无侧限抗压强度的影响，完成了海绵型水泥稳定碎石的优化设计与研究。

    Abstract：Based on the aims of sponge city，combined with the characteristics of road engineering，sponge road，based on sponge base，was proposed. The sponge road could enhance abilities of water permeating，water retaining and draining，and peak flow would be reduced，risk of water logging would be reduced. Based on skeleton dense structure of cement stabilized macadam，proposed in Specifications for Design of Highway Asphalt Pavement（JTG D50—2006），sponge cement stabilized macadam base was studied，effect of various materials on effective porosity and 7 d unconfined compressive strength were considered. Optimal design and study of sponge cement stabilized macadam were done.
