沈阳市城市道路水泥稳定碎石基层快速维修工艺的应用研究

Application Research of Rapid Maintenance Technology of Cement Stabilized Base of Urban Road in Shenyang

随着城市建设的快速发展,人们对城市道路通行能力的要求日益增加,因此对城市道路的日常维护至关重要。水泥稳定碎石基层是道路设计常用的结构形式,但因其养护期较长、影响交通,成为道路从业人员棘手的问题。沈阳市北陵大街改造项目在水泥稳定碎石中加入早强剂,缩短了行成强度时间,并采取开放轻型交通环境养护模式代替传统的养护模式,降低了城市道路基层维修对交通通行的影响。

With the rapid development of urban construction,the daily maintenance of urban road is crucial because the demand for urban road capacity is increasing.The cement stabilized base is a common structural form in road design.However,it has become a tough issue for road maintenance because of its long curing period and influence on traffic.In the reconstruction project of Beiling Street in Shenyang,the early strength agent is added into cement stabilized base and the strength formation time is shortened.In addition,the open light traffic environment maintenance mode is taken to replace the traditional mode and the impact of road base maintenance on the transportation is reduced.
