Cet article est écrit sur la base de la contribution au « XIème Forum Biodétérioration » qui a eu lieu les 4–5 juin 2012 à l’École Nationale Supérieure des Mines de Saint-Étienne.

Within the framework of a public-private cooperative research project, a reference section of grave-emulsion (GE) was laid in 2008. During its construction, various...

With the current trend in favour of reducing pollutant emissions and energy consumption, the road industry and bitumen manufacturers have also been pursuing a path of...

Asphalt mix manufacturing requires heating and the drying of aggregates. The induced energy cost has opened the way to develop alternatives processes with low energy/...

This paper reports the result of a study on the environmental impact of road construction techniques with bitumen emulsion. It describes the methodology used for data...

- Matériaux bitumineux et comportement rhéologique; - Problématique et objectifs; - Techniques expérimentales et matériaux utilisés; - Faisabilité de la technique de...

Aging of asphalt binders leads to damage on pavements, due to changes in their rheological behavior and in the binder composition. A hardening of the asphalt can be...

Use of recycled asphalt pavements (RA) in pavement rehabilitation processes is continuously growing as recycling techniques, such as cold recycling (CR), are being...

The aim of this research work is to determine the properties of a laboratory-made cold mix containing a high Reclaimed Asphalt (RA) content, and to compare them with...

Cracking in asphalt mixes is highly influenced by binder properties. Current specifications for low temperature cracking resistance are based on empirical tests or...

The process of cold recycling (CR) is becoming method of choice for pavement rehabilitation due to significantly added environmental and economic benefits....

Facing up to the increasing demand of public authorities to favour sustainable development and reduction of energy consumption, project contracting officials are...

For decades, project contracting officials have been using bitumen-in-water emulsions in the manufacture of cold mixes for wearing and base courses or surface...

In roads building, classical asphalt mix manufacturing commonly requires the heating (at 160°C) and the complete drying of aggregates. The induced energy cost has...

Les mélanges à l'émulsion de bitume sont des techniques à fort potentiel environnemental. Cependant, leur formulation, fabrication et dimensionnement relèvent encore...

Current specifications on the determination of the low-temperature cracking resistance of asphalt binders are based on empirical tests or tests involving the linear...

Asphalt pavements are obtained after mixing aggregates and bitumen both preheated in a temperature range between 100 C and 160 C. The manufacturing temperatures are...

A background RILEM interlaboratory testing is presented with some comments regarding general development and objectives for advanced testing. providing also a general...
