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

Wang, H. (author), Liu, X. (author), Zhang, H. (author), Apostolidis, P. (author), Scarpas, Athanasios (author), Erkens, S. (author)Warm mix asphalt (WMA) technology has been increasingly utilised in rubberised asphalt pavements to reduce the production and compaction temperatures and the incidental fumes and odours. This study aims to investigate the high, intermediate and low-temperature performance of crumb rubber modified asphalt binders containing WMA additives. The...journal article 2018

(author), Sluer, Berwich (author), Mohajeri, Mohamad (author)The Fibre Bragg Gratings (FBG) technology based on integrated photonics, offers specific benefits including thermal mapping, damage detection, shape- and distributed sensing. This makes it useful for determining pavement behaviour during extreme weather conditions e.g. freeze-thaw cycles when harsh winter conditions could damage the asphalt...journal article 2017

Jing, R. (author), van Lent, Diederik (author), Kasbergen, C. (author), Scarpas, Athanasios (author), Liu, X. (author), Erkens, S. (author)When oxygen diffuses in a bituminous film, it also reacts, simultaneously, with the constituents of the bitumen and as such it is gradually depleted. This depletion process masks the characteristics of the actual diffusion process and complicates the determination of the diffusion coefficient needed for computation of oxygen concentration and...conference paper 2017

Mookhoek, S.D. (author), Liu, G. (author), Erkens, S. (author), Giezen, C (author), Voskuilen, Jan (author)In this work ageing protocols for asphalt and mastics were developed and investigated; i.e representation of the field ageing and their acceleration degree. Here it was aimed to age laboratory prepared specimen analogous to naturally aged materials in the field and compare their material properties. Such simulation of ageing is of importance in...conference paper 2014
