Summary:•Porous asphalt presents a fine pellicle of bitumen in the aggregates coating.•Cellulosic fibres avoid the binder drainage.•The cellulosic fibres addition in porous asphalt is an eco-friendly solution.•Porous asphalt with cellulosic fibres show good results to permanent deformation. 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.
