Jing, R. (author), Varveri, Aikaterini (author), Liu, X. (author), Scarpas, Athanasios (author), Erkens, S. (author)Ageing of bitumen is a complex process. It is accompanied by major chemical and mechanical changes. 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 bituminous materials. Bitumen films with thickness...conference paper 2018

Jing, R. (author), Varveri, Aikaterini (author), Liu, X. (author), Scarpas, Athanasios (author), Erkens, S. (author)The ageing of bitumen has a significant impact on the mechanical behavior of asphalt concrete. In this study, Dynamic Shear Rheometer (DSR) tests were utilized to investigate the effect of ageing on the relaxation properties of bituminous materials. PEN 70/100 bitumen films with thickness of 2 mm were exposed to laboratory ageing at various...conference paper 2018

Varveri, Aikaterini (author), Avgerinopoulos, S. (author), Scarpas, Athanasios (author)This paper investigates the moisture susceptibility of European asphalt mixtures (SMA) containing reclaimed asphalt (RA) and warm mix (WMA) additives. Test sections of a typical SMA mixture have been laid, from which cylindrical samples were cored and utilized for laboratory testing. Four variants of the SMA mixture were prepared; a control HMA...conference paper 2016

On the combined effect of moisture diffusion and cyclic pore pressure generation in asphalt concreteVarveri, A. (author), Scarpas, A. (author), Collop, A. (author), Erkens, S.M.J.G. (author)In this paper, a new moisture conditioning protocol which attempts to distinguish the contributions of long- and short-term moisture damage, i.e. moisture diffusion and cyclic pore pressure generation, in asphalt mixtures is presented. The capability of the proposed protocol to rank various asphalt mixtures of known field performance for their...conference paper 2014

Pauli, A. (author), Schmets, A.J.M. (author), Kasbergen, C. (author), Varveri, K. (author), Scarpas, A. (author)Bituminous materials form a class of materials that possess the intrinsic ability to selfheal. This self-healing capability is evidenced by the observation that the service life of these materials in the field exceeds the service life as predicted by standard mechanical laboratory tests. This mismatch between laboratory prediction and field...conference paper 2013
