摘要
为充分发挥碾压混凝土(RCC)与聚合物改性水泥混凝土(PCC)的性能优势,提出了一种新型RCC-PCC复合式路面结构,从其工程设计要求、搅拌、运输、浇筑、振捣、养护工艺与经济性能等方面入手,系统地研究了RCC-PCC复合式路面工程应用的关键施工技术,提出了RCC-PCC复合式路面的工程设计要求及其具体施工工艺,在此基础上成功进行了RCC-PCC复合式路面试验路的铺筑,通过试验路工程长期性能检测,RCC-PCC复合式路面的各项路用性能指标满足设计与相关规范要求,验证了RCC-PCC复合式路面显著的性能优势与广阔的应用前景。
A new RCC-PCC composite pavement is proposed by means of analyzing the properties of roller compacted concrete and polymer modified cement concrete.The RCC-PCC composite pavement takes full advantages of RCC and PCC pavement performance.From the engineering design requirements,mixing,transport,pouring,vibrating,curing technology and other aspects of economic performance,the key applications technologies of RCC-PCC composite pavement are studied systematically.The authors propose the engineering design requirements and construction technology.On the basis,the RCC-PCC test pavement is constructed successfully.Through the long-time quality inspection test,the performances of RCC-PCC composite pavement are able to meet the requirements of correlated design specifications.The significant performance advantages and broad prospects of RCC-PCC composite pavement can be verified by the study.
