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/...

Renewable energy sources are developed worldwide due to high oil prices and to limit greenhouse gas emissions. In this context, some groups have focused their work on...

For some critical road sections, a high skid resistance of wearing course is required to minimise the risk of traffic accidents. Nowadays this skid resistance is...

Skid-resistance of trafficked roads decreases due to polishing and can have a drastic consequence on the driver safety. There is a need to dispose of a laboratory test...

The paper dealt with the use of geometric parameters to measure the degree of polishing of road surface aggregates. Microtexture asperities were characterized by two...

Cet ouvrage s'attache à élaborer une description raisonnée du processus d'agglomération urbaine en se dégageant du récit historique et culturel donc de tout...

This work focuses on the relation between the mineralogical composition of aggregates and their capacity to generate adequate friction between the road surface and the...

In the Brazilian savannah (Cerrados area), about 60 % of the surface area is used as pasture land and 30 % of the latter is cultivated pasture. Many studies have...

Skid resistance, whilst being complex, is one of the more controllable factors that road engineers can design and modify to reduce the number of wet pavement and loss...

This thesis is dedicated to the study of C60 fullerene cooling mechanisms after a nanosecond laser excitation. In this temporal mode, absorbed energy is redistributed...

The objective of this thesis is to study the deposition of thin films by plasma sputtering using moleculardynamics simulations, focusing on the mechanisms of formation...

This paper reports a study on chemical reactivity of gneiss, diorite and limestone aggregates in aqueous solution. The originality of this study is that it extended to...
