Evaluer les chaussées (Journée technique LAVOC)

Nicolas Bueche, Mehdi Ould Henia, Marc-Antoine Fénart, Mai Lan Nguyen, Alan Carter

La gestion de la maintenance du patrimoine routier, bien implantée pour les autoroutes et les routes cantonales, n’est encore que peu développée dans le cadre de réseaux routiers urbains. Cela s’explique par plusieurs raisons : faible taille du réseau, moy ...

Effect of base bitumen composition on asphalt rubber binder properties

André-Gilles Dumont, Mehdi Ould Henia

The asphalt rubber blend properties are strongly related to its base components properties. The base bitumen composition is considered as a key factor influencing the final rheological properties of asphalt rubber binder. This paper describes results from ...

Phase 2: A guide for the use of Long-Life Semi-Rigid Pavements

Nicolas Bueche, Mehdi Ould Henia

This Phase 2 Report demostrates that the technology available for long life semi-rigid pavements is not as developed as that for fully-flexible pavement types. Whereas the concept of long-life fully-flexible pavements has been adopted in some European pave ...

New Method for Pavement Rutting Prediction

André-Gilles Dumont, Mehdi Ould Henia

In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. These solicitations affect the bituminous layers that can quickly attain their permanent deformation limit resistance. This phenomenon can lead ...

Assessment of the rheological properties of asphalt rubber binder and its residual phases

André-Gilles Dumont, Mehdi Ould Henia

The asphalt rubber blends design is an empirical procedure and is quite sensitive to the variability of the components properties. A better understanding of the physical phenomenon involved during the curing process is a prerequisite step to propose a rati ...

Rheology of rubber modified bitumen with mechanical behaviour prediction

Mehdi Ould Henia

SCOPE OF THE RESEARCH • Experimental determination of the composite rheology • Modelisation of the composite viscoelastic behaviour • Investigation on the interactions between components • Proposal of predictive models for the mechanical behaviour ...

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 ...

Predictive method for evaluation of pavement rutting

André-Gilles Dumont, Mehdi Ould Henia

Pavement rutting not only decreases the road service life but also creates a danger for the security of road users. In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. It is well known that the in ...
