AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A new concept of road runoff management, based on diffuse infiltration over the shoulder, was tested in a real-scale experimentation site located near Grandson, Switzerland. This new concept consists in diffusely infiltrating the road runoff in the infiltr ...
The highway traffic size and loads have been continuously increasing all over Europe. At the same time, the expectations of users have been growing. They need more safe, durable and comfortable highway surfaces which make their trips low-cost and do not ac ...
The present study presents new flow boiling heat transfer results of R-134a flowing inside a 13.84 mm internal diameter, smooth horizontal copper tube. The heat transfer measurements were made over a wide range of test conditions: saturation temperatures o ...
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 ...
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 ...
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 ...
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 ...
Curiously, the thawing of frozen soils containing ice lenses has only been the subject of rare fundamental studies even though it is the cause of the greatest damage to constructions. The reduction of bearing capacity caused by the thawing of the ice lense ...
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 ...
In this paper an optimal shape control problem dealing with heat transfer in enclosures is studied. We have considered an enclosure heated by a flame surface (taking into account radiation, conduction and convection effects), and we look for an optimal fla ...
