Abstract

In the sustainable development context, road companies have adopted an approach which aims at accelerating convergence between environmental requirements and development of energy-saving materials called ?warm and half-warm asphalt mixes?. This study, realized in Laboratoire Central des Ponts et ChaussÚes (LCPC) within the framework of a partnership between EIFFAGE Travaux Publics and LCPC aimed at determining the influence of the mix composition on the environmental properties of the half-warm mix asphalts compared to hot mix asphalt--acting as reference materials. By means of the factorial experiment design approach, this study highlights the influence ofthe bitumen chemical nature, the additive origin and the water content onfumes generated during the manufacturing stage.
