摘要
级配碎石基层材料的抗剪强度是影响沥青路面抗车辙能力的关键技术指标。本文通过试验,系统分析了含水量、剪切速率和围压等因素对级配碎石基层材料抗剪强度的影响规律,可为公路工程建设中获得高抗剪强度的级配碎石基层材料提供基础参考。
The shear strength of the graded macadam base material is the key technical index that influences the resistance to rutting capability of asphalt pavement. The influence law of water content, rate of shear and confining pressure on the shear strength of the graded macadam base material were ana- lyzed systematically through experimenting. These can provide some basic references for obtaining high shear strength graded macadam base material in the highway engineering construction.
