摘要
通过室内冻融劈裂、车辙、低温劈裂、四点弯曲疲劳等试验研究分析不同离析程度对AC-20、AC-13沥青混合料工作性及路面性能的影响,试验表明:离析对AC-20、AC-13沥青混合料的和易性、水稳定性、高温稳定性及低温劈裂抗拉强度及抗疲劳能力及均有较大影响。应严格控制沥青混合料离析的发生,避免沥青路面出现损坏。
Through the indoor freezing and thawing splitting,rutting,low-temperature splitting,four-point bending fatigue and other experiments to study and analyze the influence of different segregation degree on the workability and pavement performance of AC-20,AC-13 asphalt mixtures.The results show that segregation has great influence on compatibility,water stability,high temperature stability,low temperature splitting tensile strength and fatigue resistance of AC-20,AC-13 asphalt mixtures.The occurrence of segregation of asphalt mixture should be strictly controlled to avoid damage to asphalt pavement.
