At early age, ultra high performance fibre reinforced concretes (UHPFRC)undergo significant volumes changes (thermal deformation and autogenous shrinkage)related to their composition. These deformations can be restrained by different elements respective to ...
In the field of ITS applications evaluation, micro- simulation is becoming more and more a useful and powerful tool. In the evaluation process, one of the most important steps is the safety analysis. For that purpose, classical micro- simulation outputs gi ...
In creating Terms of Reference, the Group has to consider the scope of the meaning of long-life pavements. It is suggested that this should not be ‘life’ related but based on the concept that a long-life pavement is one that is heavily trafficked, and is d ...
Il s'avère aujourd'hui important de développer de nouvelles techniques de maintenance en accord avec les principes du développement durable. Dans ce sens, la récupération de matériaux bitumineux issus de la réfection d'anciennes chaussées peut contribuer à ...
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 ...
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 anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. Three full-size test sections were built in a test hall for ALT named Halle-fosse ...
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 ...
Temperature variations are particularly harmful to wearing courses with asphalt mixture. During wintertime, and especially, at very low temperatures, a surface cracking may appear and propagate more or less rapidly. An experimental investigation has been c ...
In anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. These mixtures make possible to reduce rut in base courses. With a temperature of ...
