摘　　要：通过借鉴骨架结构具有继承性的思想对粗集料进行分级组合CBR室内试验,以所得到的粗集料CBR作为评价指标,CBR值越大,骨架越强,得到AC—13粗集料颗粒组成的最优骨架及整个粗集料为最优骨架的比例组成并确定最强骨架级配范围,并与捣实密度试验的骨架结构进行比较分析,为骨架密实型沥青混合料设计提供依据。By drawing a succession of the skeleton structure ,it will carry on the graduation combination Laboratory CBR Test,using the CBR of coarse aggregate which is obtained from the experiment as a appraisal target, the more bigger of CBR, the more stronger of coarse aggregate skeleton, then obtain the AC-13 coarse aggregate particles composed of optimal skeleton and the whole coarse aggregate for the optimal ratio of the skeleton and to determine the scope of the strongest skeleton grading and analysis the skeleton structure of the ram density experiment, provide the basis for the design of Asphalt mixture with skeleton dense structure.
