摘　　要：以AC-13C型沥青混凝土路面为研究对象,进行了试件的马歇尔、浸水马歇尔、冻融劈裂和车辙试验,得到这些性能指标随油石比的变化关系,分析了马歇尔稳定度控制指标偏低对混合料路用性能的影响。结果表明,在沥青路面施工质量的检验过程中,马歇尔稳定度指标偏低会导致混合料水稳性和抗车辙能力达不到规范要求;为得到较佳的路面质量,混合料冻融劈裂残留强度比和车辙试验动稳定度也应作为检验指标加以考虑。Marshall test, immersion Marshall test, frozen-thaw and split test and rutting test were conducted on AC-13C asphalt concrete pavement. The Curve of these indexs was obtained at different oil-stone ratios, and the influence of lower Marshall Stability index on the pavement performance of asphalt mixture was studied. Results and analyses show that lower Marshall Stability index would induce that water stability and rutting resistibility of asphalt mixture can not meet the demand of the criterion. To acquire good asphalt pavement quality, the indices of frozen-thaw and split strength ratio and rutting test dynamic stability should be regarded as necessary ones to be examined for obtaining the optimal asphalt mixture oil-stone ratio.
