摘要
以重庆旧路改造工程为依托介绍了C-ETM半柔性基层材料的组成设计、性能及工程实施效果;引入劈裂强度和最佳流体含量为主要控制指标,并提出以最佳级配、最佳流体含量、最佳沥青含量、最佳水泥含量的步骤来确定最佳配合比的方法;通过试验研究及实体工程检验发现,C-ETM半柔性基层材料具有良好的路用性能,并成功地运用于城市道路改建工程。本文的研究成果为C-ETM半柔性基层材料推广及应用提供了宝贵的经验。
With the backing of existing roads modification project of Chongqing, constitution design, performance and practical effect of materials of C-ETM semi-flexible base are introduced. Splitting strength and optimal fluid content are brought in as major control indexes. A method that follows the steps of optimal graduation, optimal fluid content, optimal asphalt content and optimal cement content is presented to determine the optimal mixing proportion. The experimental study and practical use indicate that C-ETM has great performance, and also successfully adopted in urban road rebuilding project. The result of study provides precious experience for popularization and application of C- ETM.
