广州国际体育演艺中心透水混凝土道路施工技术

Construction technique of pervious concrete pavement in Guangzhou international sports and performance arts center

广州国际体育演艺中心道路工程采用了透水混凝土技术。介绍了该道路工程的基层处理方法,原材料选择、配合比参数与测试指标值,以及施工工艺流程,并分析了配合比设计、搅拌与浇筑、养护方面的技术难点,提出了相应对策。该工程经历了十一年雨季的考验,透水效果优,道路功能正常。

Pervious concretepavement technique was adopted in Guangzhou international sports and performance arts center.Roadbaselayer treatment method,raw material selection,concrete mix ratio parameter,physical and mechanical property index value,and construction technique processof the pavement engineeringare introduced.Key technique questions,such as,design of mix proportion,mixing,casting and curing of concrete,are analyzed,and the relative solution are put forward.The pavement engineering has passed through rainy season during the past eleven years,and showed excellent pervious performance,and good functioning of pavement.
