The E&E Congress, which took place recently in Prague, included a technical programme, which consisted of over 250 papers. The Poster Session held during the conference attracted many interested visitors.
Above we see Jenny-Ann Östlund, Nynas, discussing the research paper ’Production and durability of cold mix asphalt’ (co-author Roger Lundberg, NCC Roads, Torbjörn Jacobson, Trafikverket, and Per Redelius, Nynas) with a Congress attendee.
Cold mix technology is shown to be a sustainable option that can be used to produce roads with a high durability over time.
The long-term durability of polymer modified bitumen in bridge deck pavements has been the focus of research by Nynas experts Xiaohu Lu, Bengt Sandman, Henrik Arnerdal and Helene Odelius.
‘The effect of binder composition and properties on the water sensitivity of asphalt mixtures’ by Ian Martin Lancaster and Ian Michael Lancaster of Nynas compares two standard methods frequently used in the UK to determine asphalt’s resistance to the effects of water.
