摘要： 连续配筋混凝土路面(CRCP)行车舒适,基本不需要养护,使用寿命长,具有广阔的应用前景。从影响因素、结构分析方法、设计方法、施工技术等方面介绍了CRCP的国内外研究现状。不同于1993版的AASHTO路面设计指南,AASHTO 2002开始直接以冲断和平整度作为CRCP的设计指标,国内CRCP的研究与国外相比尚存在很大差距。在分析现有研究不足的基础上,指出了CRCP研究的发展趋势,即根据裂缝宽度和裂缝间距的分布进行冲断预估,在重复车辆荷载及环境因素作用下进行裂缝宽度预估,考虑裂缝(或接缝)间的传荷能力和板底脱空计算板顶的临界横向应力,对连续配筋混凝土基层沥青路面进行系统研究及基于路用性能的要求对各结构层材料组成进行研究等。

Abstract: Continuously reinforced concrete pavement (CRCP) is smooth and almost needs no maintenance,which has long service life as well as a promisingly potential application.CRCP is introduced in detail from design factors,structural response analysis,design,construction,and et al.Different from 1993 Design Guide of AASHTO,2002 Design Guide selects punchout development and smoothness as design criteria.The research on CRCP at home has been still far behind that at abroad.Based on the analysis of the faults in previous research on CRCP,it is pointed out that the research on CRCP in the future will be focused on the following aspects:punchouts prediction based on the distribution of transverse crack width and spacing,crack width prediction under repeated vehicle-load and natural conditions,the calculation of the critical transverse stress at the top of the slab when the loss of base support and the Load Transfer Efficiency (LTE) of cracks or joints are considered,the asphalt pavements with the base course made up of continuously reinforced concrete,and the material composition design of different structural course according to their performance requirement.
