Modélisation et prédiction du comportement rhéologique des mélanges bitume caoutchouc

Mehdi Ould Henia

Asphalt rubber is a modified binder widely used in pavement construction. Composition design methods of asphalt rubber blends are exclusively empiric and rely on the selection of the optimal combination of parameters after a long experimental program. The ...

Design and Performance of Hot Mix Asphalts with High Percentages of Reclaimed Asphalt: Approach followed in the Paramix Project

The use of reclaimed asphalt pavement (RA) in new asphalt pavements can provide important economical savings, while reducing the negative environmental impact. The European research project PARAMIX aims to improve the techniques for hot mix recycling in pl ...

Thermomechanical and mechanical behaviour of asphalt mixtures at cold temperature. Road and laboratory investigations

André-Gilles Dumont, Thierry Pucci

Temperature variations are particularly harmful to wearing courses with asphalt mixture. During wintertime, and especially, at very low temperatures, a surface cracking may appear and propagate more or less rapidly. An experimental investigation has been c ...

Résistance mécanique d'enrobé avec matériau recyclé

Il s'avère aujourd'hui important de développer de nouvelles techniques de maintenance en accord avec les principes du développement durable. Dans ce sens, la récupération de matériaux bitumineux issus de la réfection d'anciennes chaussées peut contribuer à ...
