Abstract(s)

The porous asphalt (PA) use in road pavements surface layers is one of the most common solutions worldwide to address the climate changes impact like heavy rain. The aim of this study is to evaluate the performance of these mixtures with the cellulosic ﬁbres addition, known for their adherence capacity between the aggregates and the binder. These will help to prevent the binder loss by drainage, which is one of the main problems of porous asphalt, since the ﬁne aggregates content is reduced. Comparing to the conventional porous asphalt the cellulosic ﬁbres addition improved performance to permanent deformation.
