Jing, R. (author), Apostolidis, P. (author), Liu, X. (author)In this study, a series of viscosity tests were performed to investigate various conditions, i.e. temperature, shear rate and dilution level, on the curing behavior of epoxy bitumen. The results show that curing rate of epoxy bitumen increased with temperature; high shear rate would interfere the formation of crosslinks in epoxy bitumen,...journal article 2022

Zhang, Y. (author), Liu, X. (author), Ren, S. (author), Jing, R. (author), Lin, P. (author), Apostolidis, P. (author), Erkens, S. (author), Wang, Xuancang (author), Scarpas, Athanasios (author)Lignin, one of the most abundant natural polymers, has been extensively studied as an additive in bituminous binders. Even though the lignin improves the overall resistance against oxidative aging of bitumen, it could lead to high thermal cracking sensitivity. In this study, a bio-oil (i.e., rapeseed oil) is implemented in lignin-modified...journal article 2022

Jing, R. (author), Varveri, Aikaterini (author), Liu, X. (author), Scarpas, Athanasios (author), Erkens, S. (author)Ageing has a significant impact on the chemical and mechanical behavior of bituminous materials. In this study, Fourier Transform Infrared (FTIR) spectrometer and Dynamic Shear Rheometer (DSR) tests were utilized to investigate the effect of ageing on the chemical and mechanical properties of bitumen. Bitumen films with thickness of 2 mm were...book chapter 2019
