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 ...

SAMARIS D26 - Modelling of UHPFRC in composite structures

Emmanuel Denarié, Hamid Sadouki

The extremely low permeability of Ultra-High Performance Fibre Reinforced Concretes (UHPFRC) associated with their outstanding mechanical properties make them especially suitable to locally "harden" reinforced concrete structures in critical zones subjecte ...

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 ...

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 ...

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 ...

Role of cement in improving concrete durability

Karen Scrivener

The role of cement in improving concrete durability is complex. Generally the role played by cement is secondary to the role of concrete mix design and curing. Some of these interacting effects are illustrated by discussing the roles of calcium hydroxide, ...

Towards tailored superplasticizers

Paul Bowen, Yves Houst, François Perche

Superplasticizers (SP) of the “new generation” are essentially polycarboxylate polymers. Polymers of this family can be produced with almost infinite variations in their chemical structure, which allow the fulfilment of specific (tailored) properties. Thes ...

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 ...

Long term effect of modified binder on cracking resistance of pavements

André-Gilles Dumont, Mehdi Ould Henia

Combined loading and climatic effects associated with the choice of high modulus bituminous mixtures, in order to prevent the pavements from rutting, have increased the risk of cracking failure in the bituminous layers. It was decided, in 1989, to start a ...
