Asphalt Mixture with RAP: Mix Design Optimization

André-Gilles Dumont, Michel Pittet, Nicolas Bueche, Sara Bressi

The addition of reclaimed asphalt pavement (RAP) in hot mix asphalt is now common practice in Switzerland. With the increases of RAP content in asphalt mixture, the problematic of the mix design optimization becomes an important issue to be considered. The ...

International Journal of Pavement Engineering

André-Gilles Dumont, Nicolas Bueche, Sara Bressi

This paper evaluates the variability of binder rheology for different ageing levels and the influence of ageing at different testing temperatures. Three different ageing levels were applied on a single type of bitumen with a penetration grade of 70/100.The ...

Asphalt mixture choice: a decision-aid model

Nicolas Bueche

Due to the continuous development of warm mix asphalts (WMA) as alternatives to hot mix asphalts (HMA), the choice of the most favourable mixture for a given project is not necessarily straightforward. When considering greenhouse gas (GHG) emissions and en ...
