A new laboratory methodology for optimization of mixture design of asphalt concrete containing reclaimed asphalt pavement material

The reduction of virgin bitumen added to asphalt mixtures containing Reclaimed Asphalt Pavement (RAP) is based on the typical assumption that all the aged binder function in the same way as the virgin binder. However, recent studies conducted by the author ...

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 ...

An advanced methodology for the mix design optimization of hot mix asphalt

André-Gilles Dumont, Sara Bressi

The bitumen quantity to add to asphalt mixtures depends on the surfaces of aggregates and filler to be coated. The formulas currently available in the literature have limitations such as considering all the fillers with the same specific surface or the agg ...

A framework for characterizing RAP clustering in asphalt concrete mixtures

André-Gilles Dumont, Sara Bressi, Michel Pittet

Recycled Asphalt Pavement (RAP) is commonly used in asphalt for road rehabilitation or new constructions. Nevertheless, some physical and chemical phenomena that occur during production, laying and compaction of mixtures containing RAP are not yet complete ...

Multiscale imaging and characterization of the effect of mixing temperature on asphalt concrete containing recycled components

Sara Bressi

When producing asphalt concrete mixture with high amounts of reclaimed asphalt pavement (RAP), the mixing temperature plays a significant role in the resulting spatial distribution of the components as well as on the quality of the resulting mixture, in te ...

Particle clustering phenomena in hot asphalt mixtures with high content of reclaimed asphalt pavements

André-Gilles Dumont, Sara Bressi

One challenge in efficient recycling of asphalt concrete is the adherence of the reclaimed asphalt pavement (RAP) particles or clustering that inhibits fulfilling the aggregate gradation requirements. In order to investigate this phenomenon two types of mi ...

Cluster phenomenon and partial differential aging in RAP mixtures

André-Gilles Dumont, Sara Bressi, Michel Pittet

The present study defines a procedure for gaining a better understanding of the interaction between the aged and the virgin binders and what actually occurs during a mix process. Indeed, the authors propose a methodology to determine and quantify the clust ...

Asphalt Mixture with RAP: Mix Design Optimization

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

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 ...

Dimensionnement des chaussées: état actuel et évolution

André-Gilles Dumont, Sara Bressi

Les chaussées sont soumises aux effets des charges et doivent s’adapter aux évolutions du nombre et des types de véhicules. Pour tenir compte du changement climatique constaté et des récents développements au niveau des matériaux de chaussées, nous devons ...
