针对目前水泥混凝土路面的结构特征和缺陷,研发双层连续配筋混凝土路面(CRCP)新结构,上基层采用贫混凝土,下基层采用沥青碎石或级配碎石,基层和面板之间设细型沥青混凝土夹层;面板设上、下2层连续钢筋,通过专门设计的支座固定,其中上层只设纵向钢筋,下层设纵横向钢筋;研发适用于双层CRCP新结构的接缝及施工方法,保持接缝处钢筋连续,有效解决现有接缝存在的问题。研究结果表明:双层CRCP新结构的疲劳寿命得到有效提升,在不良地基与板底脱空不利状况下更具优势和适用性;新型路面结构的部分技术特征已在实体工程中得到有效应用,且横向裂缝及平整度等关键技术指标满足要求;所提出的设计方法可为CRCP合...

Aiming at the structure characteristics and the flaws of the existing of cement concrete pavement, a new double-layer continuously reinforced concrete pavement(CRCP) structure was developed and the optimized design with lean cement concrete at the surface base, and asphalt macadam or graded broken stone was used in the grassroots, thin asphalt concrete layer between the base course and the panel. Two layers of panel of continuous steel up and down were set up, and panel was fixed by specially designed bearings, the surface layer adopted longitu...
