Sun, Z. (author), Kasbergen, C. (author), van Dalen, K.N. (author), Anupam, K. (author), Erkens, S. (author), Scarpas, Athanasios (author)Maintenance and rehabilitation strategies of pavements are usually made based on the results of performance evaluation. An efficient tool for pavement structural evaluation at network level is the traffic speed deflectometer (TSD) test. In order to deal with TSD measurements, this paper proposes a parameter back-calculation technique. Firstly,...conference paper 2020

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

Apostolidis, P. (author), Pipintakos, G. (author), Liu, X. (author), van de Ven, Martin (author), Erkens, S. (author), Scarpas, Athanasios (author)Epoxy modified bitumen (EMB) is a promising technology for long lasting paving materials ensuring higher resistance to rutting, oxygen- and moisture-induced damage. In this paper, an analysis of the chemical reactions that take place during the chemical hardening process (curing) of epoxy modified bitumen<br/>was conducted by means of Fourier...conference paper 2018
