The bitumen and asphalt industries will come together at the congress in Prague. The congress includes a technical programme, which consists of over 250 papers presented. Several research papers that Nynas has been involved with are included in the official proceedings of the E&E Congress.
The research paper ’Production and durability of cold mix asphalt’ by Roger Lundberg, NCC Roads and Torbjörn Jacobson, Trafikverket, with Per Redelius and Jenny-Ann Östlund, Nynas, sought to understand the benefits of cold mix technology on heavily trafficked roads. Technical understanding of the technology has improved, making future production easier and more reliable.
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 High Coast Bridge in Sweden was constructed in 1997 with PMBs used in all asphalt layers. Fifteen years on, performance of the pavements was excellent, and asphalt samples were collected to study the durability of the modified binder.
‘The effect of binder composition and properties on the water sensitivity of asphalt mixtures’ by Dr Ian Martin Lancaster and Mr Ian Michael Lancaster of Nynas compares two standard methods frequently used in the UK to determine asphalt’s resistance to the effects of water. The Indirect Tensile Stiffness Modulus (ITSM) of the field-exposed asphalt samples was evaluated over a two year period and compared to those obtained under the standard methods.
A recently developed device for determining an asphalt mixture’s resistance to permanent deformation has been tested by the Swedish National Road and Transport Research Institute (VTI) and Nynas. The paper, ‘Shear box tester for characterization of polymer modified bituminous mixtures’ by Abubeker Ahmed and Safwat Said of VTI and Xiaohu Lu, Nynas, analyses several types of conventional and polymer modified asphalt specimens from a test road using the new tester.
