级配碎石作路面基层材料的动三轴力学性能试验研究
Test and Research on Dynamic Triaxial MechanicsCharacteristics of Graded Broken Stone Used asPavement Foundation Material
【摘要】 通过级配碎石室内动三轴力学性能试验,分析研究级配碎石的动力特性,获取级配碎石近似的回弹模量值。 级配碎石用于高等级公路、城市道路沥青面层与半刚性基层间的过渡层,可有效防止沥青路面反射裂缝,对合理取用 级配碎石回弹模量具有重要的参考价值。
【Abstract】 Based on indoor dynamic triaxial test of graded broken stone, analysis is made on its dynamic characteristics and its approximate rebound modulus is obtained. The application of graded broken stone in high -grade highways, asphalt pavement of urban roads etc would prevent reflection crack of asphalt pavement.
