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

André-Gilles Dumont, Sara Bressi, Manfred Partl

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 ...

Advanced methodology for optimization of mixture design of asphalt concrete containing reclaimed asphalt pavement material

Sara Bressi

Despite the massive use of Reclaimed Asphalt Pavement (RAP) in Hot Mix Asphalt (HMA) production, the chemo-physical phenomena that characterise the fabrication of these mixtures have not yet been completely explored. The detection and understanding of thes ...

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

André-Gilles Dumont, Sara Bressi, Manfred Partl

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 ...

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

André-Gilles Dumont, Sara Bressi, Manfred Partl

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 ...

Measurements and modelling of residual stresses during quenching of thick heat treatable aluminium components in relation to their precipitation state

Nicolas Paul Henry Chobaut

In the fabrication of heat treatable aluminium parts, solutionising and quenching are key steps in order to obtain the required mechanical characteristics. Fast quenching is necessary to avoid coarse precipitation as this one reduces the mechanical propert ...
