Road trials with vegetable oil based bitumen in Norway

Two trials with vegetable oil based binders were conducted in Norway. The first trial was an application in Hot Mix Asphalt (HMA) using vegetable oil based viscosity grade V10000 bitumen and conventional V10000 bitumen as a reference. V-grade binders, being very soft bitumen grades, are typically used on low volume roads in Scandinavia where poor and varying bearing capacity often requires flexible asphalt layers. A second binder BL9000R was developed for a fast moving train hot surface dressing application. Comparative laboratory analysis on the vegetable oil based binders and reference binders as well as mixtures were performed for both trials. In the comparison of the two V10000 binders, it was seen that the vegetable oil based binder was less temperature susceptible. The laboratory testing for the surface dressing trial did not reveal any significant differences between the vegetable oil based BL9000R and the reference BL9000R. In the field application of V10000 and BL9000R in the two trials, fewer emissions were observed for the vegetable oil based binders. For the covering abstract see ITRD E157233
