摘　　要：劈裂试验是检测半刚性基层材料抗拉强度的一种方法.通过对半刚性基层材料劈裂强度的试验研究,探讨了劈裂强度作为半刚性基层材料强度控制指标的可行性,并给出了相应的劈裂强度控制标准.通过在省道S102周口至项城段改建工程中施工质量控制的实际应用,并对施工质量进行了评价分析.研究结果表明,劈裂强度作为半刚性基层的强度控制指标是合理的,并且具有试验简便、操作方便等特点,对于半刚性基层的设计与施工具有重要的参考价值.The splitting experiment is one way to test the tensile strength of semi-rigid base material.According to the experiment of splitting strength,the possibility of the splitting strength as the strength standards of the semi-rigid base is discussed and the corresponding standards are given.The standards are used in S102 Road from Zhoukou to Xiangcheng to control the construction quality,and the results are analyzed.The results show that the split strength as the strength standard of the semi-rigid base material is reasonable,and the experiment is simple,easy working.For the design ＆ construction of semi-rigid,it could be an important reference.
