Applications of depth‑sensing indentation on asphalt materials: A review
https://orcid.org/0000-0001-8378-5621
Highlights: The successful applications of depth‑sensing indentation on asphalt materials were reviewed. The basic principle, analysis method and experimental key points of depth‑sensing indentation were summarized. ‘The challenges and suggestions of depth‑sensing indentation on the applications of asphalt materials were presented. Prospect of depth‑sensing indentation were suggested.
Abstract Depth‑sensing indentation is a powerful testing technology used to quantitatively characterize the mechanical properties of asphalt materials at different scales. Besides hardness and Young's modulus, rich micro mechanical properties such as adhesion and stiffness can also be obtained by the load-displacement curve from the depth‑sensing indentation. Furthermore, depth‑sensing indentation provides an efficient approach to investigate the mechanical properties of aggregate, asphalt binder, asphalt mastic, and interface zone (ITZ) without separating them from the asphalt mixture, which is of value for investigating the microstructure properties and building numerical models of asphalt mixture. In this review, the key theoretical and experimental procedure of depth‑sensing indentation are discussed, including basic principle, analysis method, sample preparation, and parameter selection. Moreover, the applications of depth‑sensing indentation in phase and ITZ identification, numerical models, aging, moisture susceptibility, and modifiers investigation of asphalt binder, mastic, and mixture are concluded in detail. The challenges for the applications of depth‑sensing indentation on asphalt materials are also presented with some suggestions for further development.
