沥青稳定碎石动静模量测定对比试验研究

Research on contract experiment for determination of dynamic and static modulus of asphalt stable gravel

选用沥青稳定碎石的抗压回弹模量和动态模量来表征材料的基本力学性能,测定了ATB-30和ATB-40两种级配、30号和70号两种沥青组成的沥青稳定碎石的抗压回弹模量和动模量,对比了不同条件对沥青稳定碎石模量的影响规律,并运用数理统计方法,建立了抗压回弹模量和动模量的相对关系。

Choosing compressive rebound modulus and dynamic modulus of asphalt stable gravel to represent the basic mechanical properties of materials,the thesis determined the compressive rebound modulus and dynamic modulus of asphalt stable gravel consisted of asphalt 30# and asphalt 70# and the asphalt stable gravel of ATB-30 and ATB-40,contrasted the influence rules of different conditions to asphalt stable gravel,using mathematical statistics,it set up the relationship between compressive rebound modulus and dynamic modulus.
