摘　　要：基于动态温度扫描试验对TLA混沥青的高温粘弹性能进行了研究,通过对TLA混合沥青的高温动态粘弹性能的变化规律以及Han曲线的温度依赖性进行分析,得出了TLA混合沥青的储存模量和损耗模量随温度和TLA掺量的变化规律,并比较了不同掺量的TLA混合沥青与基质沥青Han曲线的差异,根据这个差异可以很好的评价TLA混合剂与基质沥青的相容性.研究结果表明了该试验可以很好地分析TLA混合沥青的高温粘弹性能,从而为更好地为推广应用TLA混合沥青提供理论依据.Based on the dynamic temperature sweep test,the viscoelastic properties of the TLA mixed asphalt were studied,by studying the high temperature dynamic viscoelastic properties and the Han curve,this report studied the TLA mixed asphalt storage modulus the amount of difference and loss modulus variation with temperature and TLA content,and compared the different contents of TLA mixed asphalt Han curve,the difference can prove the TLA and basic asphalt compatibility.The results show that the test can be a good analysis of the viscoelastic properties of TLA mixed asphalt temperature,so as to better promote the use of TLA mix asphalt provides a theoretical basis.
