摘要
结合连续配筋混凝土路面(CRCP)在国内应用中出现问题,针对市政道路CRCP的特殊情况提出一套具体的设计处理方式,并对施工、养护及验收标准提出指导建议。为更好推进CRCP的应用,建议在基层摩阻系数、干缩及混凝土强度随时间的增长曲线等方面作进一步研究,以更好地控制横向裂缝的发展。
In view of the problems occurring in the domestic application of continuous reinforced concrete pavement(CRCP),a set of specific design methods for the special situation of the municipal road CRCP is put forward,and the guiding proposals for the construction,maintenance and acceptance standards are proposed.In order to better promote the application of CRCP,further research on the friction coefficient,drying shrinkage and the growth curve of concrete strength with time is proposed in order to better control the development of transverse cracks.
