文章针对河南省沥青路面面层材料设计参数的不合理性,利用MTS等试验仪器实测了河南省3种典型沥青面层材料的20℃与15℃抗压回弹模量及15℃劈裂强度,提出了河南省3种典型沥青面层材料设计参数推荐值。同时,为利用试验简便、稳定性好的劈裂强度值估算出抗压回弹模量,确定了15℃河南省典型沥青混凝土劈裂强度与同温度下抗压回弹模量之间的对比系数取值为0.76‰。研究成果为河南省道路设计和施工控制提供参考。
According to the unreasonable design parameters of asphalt pavement surface materials in Henan Province, the compressive resilience modulus at 20 ℃ and 15 ℃ and the splitting strength at 15 ℃ of three kinds of typical asphalt surfacing materials in Henan Province were measured by MTS and other testing instruments. , Proposed three kinds of typical asphalt surface material design parameters recommended values in Henan Province. In the meantime, in order to estimate the compressive resilience modulus by using the splitting strength value with simple test and good stability, the comparison between the splitting strength of typical asphalt concrete in Henan Province at 15 ℃ and the compressive resilience modulus at the same temperature The coefficient is 0.76 ‰. The research results provide a reference for road design and construction control in Henan Province.
