| 摘 要： | 在室内冻融劈裂试验的基础上,评价以石灰石集料拌制的沥青混合料的水敏感性，分析沥青用量、级配组成和压实度等因素对沥青混合料冻融劈裂强度比TSR的影响。试验与分析结果表明：在组成设计不当和压实度不足的情况下，石灰石沥青混合料也可能出现水稳定性不足的问题。

| Abstract: | The moisture susceptibility of hot mix asphalt (HMA) produced by limestone aggregate was evaluated on the basis of split test of a freeze and a thaw.The factors affecting on the retained tensile strength TSR of HMA,such as asphalt content,grading and compatibility were analyzed.The results indicated that HMA batched by limestone aggregate may be damaged by water stripping in case of inadequate compaction level and inadequate mix design. |
