超薄水泥混凝土加铺技术是一种以较少资源来恢复旧路面使用功能的技术,近年来在国内外得到了广泛的关注。该文结合中国现行的路面设计和相关超薄水泥混凝土罩面试验数据,分析了超薄水泥混凝土路面板的最不利荷位、层间粘结对角隅裂缝的影响,采用了轮迹分布曲线对板接缝进行合理划分,并通过分析层间刚度对反射裂缝进行了讨论,为改善超薄水泥混凝土的性能提供借鉴。
Ultra-thin cement concrete paving technology is a less resource to restore the use of the function of the old pavement technology in recent years at home and abroad have received widespread attention. Based on the current pavement design and the related ultra-thin cement concrete overlay test data in China, the paper analyzes the influence of the most unfavorable charge of the ultra-thin cement concrete pavement slab and the influence of interlayer bonding on the corner crack. The reasonable division of the joint of the slab is discussed, and the reflection cracks are analyzed by analyzing the interlayer stiffness, so as to provide reference for improving the performance of the ultra-thin cement concrete.
