近几年江苏省城市道路、高等级公路路面基层绝大部分采用水泥稳定碎石基层,其优点是早期强度高、刚性大,易于集中拌和摊铺等优点。其缺点是混合料技术指标控制不好或受外界环境、温度、气候、荷载的影响,水稳碎石基层易产生裂缝,而目前处理裂缝又没有成熟的办法和相关技术措施。本文根据平时在工作中的一些经验及做法进行成因探讨和提出防治措施。 In recent years, Jiangsu Province, urban roads, high-grade highway pavement mostly used grass-roots level cement stabilized gravel, which has the advantage of early high strength, rigid, easy to concentrate mixing paving and so on. The disadvantage is that the mixture of technical indicators are not well controlled or affected by the external environment, temperature, climate, load, water-stabilized gravel easy to crack, and the current cracks and no mature approach and related technical measures. This article based on some of the usual experience in the work and practice causes and prevention measures.
