Review on the High Temperature Performance Evaluation Indexes of Asphalt Binder
摘要
Abstract
Using different indicators to evaluate the high temperature performance of the same asphalt binder may get different results.In order to quickly and accurately analyze the high temperature perform-ance of asphalt binders,it's very important to select a suitable evaluation index.Firstly,this article sum-marizes the limitations of conventional indicators such as penetration,softening point,60℃dynamic vis-cosity,and rutting factor in evaluating the high temperature performance of asphalt binders.Secondly,new indicators are introduced,including modification rutting factor G#/(sinδ)9,viscous part of complex shear modulus Gv and non-recoverable creep compliance Jnr,then the characteristics of these new indicators are analyzed and research results obtained by using each indicator are reviewed.Finally,this paper puts forward sugges-tions for the revision of relevant norms in my country and the future development is prospected.关键词
