Application of Differential Scanning Calorimetry as Advanced Asphalt Testing Technology: A Comprehensive Review

引用

Journal of Traffic and Transportation Engineering(English Edition) 2024年

作者： Hangtian ni Jianmin Ma Daquan Sun Lei xu Senlin ling Mingjun Hu Key Laboratory of Road and Traffic Engineering of Ministry of Education， Tongji University Department of Chemistry， Queen's University Kingston School of Transportation and Logistics， Dalian University of Technology

Understanding the thermal mechanism of materials is paramount in the selection， modification， and application of asphalt binders. Differential scanning calorimetry (DSC)， as a thermodynamic technology， offers an efficient approach to assess the thermal properties of asphalt and unveil the underlying mechanisms. This review first introduces the measurement principle， sample preparation， and parameter selection in DSC. Subsequently， the review systematically explores the specific applications of DSC in the asphalt domain， encompassing thermal analysis， performance evaluation， aging investigation， and modification research. DSC， with its high precision and sensitivity， can discern essential differences between asphalts， reflecting their formation processes， disclosing their thermal histories， and predicting their properties. Serving as a fast intrinsic characterization technique， DSC establishes a connection between thermodynamic characteristics and other asphalt material performances， thus broadening its application scope. The review can serve as a potential guide for researchers to investigate the behavior mechanisms of asphalt binders from a thermodynamic perspective， demonstrating the prospects of DSC as an evaluation tool containing multifaceted information about asphalt.
