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
On the basis of indoor freeze-thaw splitting test, water sensitivity of asphalt mixture mixed with limestone aggregates was evaluated. Factors such as asphalt dosage, grading composition and compaction degree were analyzed to evaluate the freeze-thaw splitting strength ratio The impact of TSR. The results of the tests and analyzes show that the problem of insufficient water stability may also occur in limestone bituminous mixes with poorly designed components and inadequate compaction
