摘　　要：针对国道110(G110)兴和-呼和浩特段改扩建工程采用露石水泥混凝土(EACCP)工艺后,路面出现断板的现象,通过对当地自然环境、设计因素、施工方法以及其他方法的原因进行了分析,并通过分析结果提出了处理措施。根据路面破坏程度的不同,处理措施主要为裂缝修补、局部修复和整板更换3种。为了预防路面在今后运行期间出现断板,提出对现有路面进行切割以释放应力的方案。文章可为今后在内蒙古地区进行EACCP施工提供借鉴。Aimed at the emerging of breakage after applying the technology of exposed-aggregate cement concrete pavement （EACCP） to the reconstruction of Xinghe Hohhot section of the national highway G110, analysis on local environment, design and construction was conducted, and treatment measures were proposed based on the results. Three measures, including crack repair, partial repair and replacing, were available for pavements with different extents of damage. In order to avoid the breakage during operation, a plan of cutting the existing pavement for stress release was put forward, which provides reference to the construction of EACCP for Inner Mongolia.
