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 ...
With the current concerns about sustainable development and greenhouse gas emissions in various fields, the road domain has also to contribute. Indeed, asphalt mixture production is a very important energy consuming phase in order to heat the aggregates an ...

Temperature highly affects pavement performance. High and low temperatures not only affects the viscosity of asphalt concrete but also has an impact on the moisture flow within pavements. At temperatures below 0°C the freezing of pavements dramatically cha ...

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 ...

New Road Construction Concepts (NR2C) is a FEHRL-project supported by the European Commission under the Sixth Framework Programme. NR2C develops perspectives and specific innovations, so that long-term visions are linked to short-term action. One of the id ...
One of the most important research efforts developed to date is the European Project ELLPAG (European Long-Life Pavement Group). It was founded, in 2002, as a FEHRL group to gather the European knowledge. The group has been active since then, and it has be ...
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 ...

This paper presents a finite element analysis modeling of rutting. The behaviors of the asphalt concrete is described using an elasto-viscoplastic constitutive relation, while an elastoplastic constitutive relation is used for the lower layers. The model a ...
