Recent advances in pavement design suggest the use of a combi-layer (grouted porous asphalt) instead of the traditional asphalt concrete for the wearing-course in case of heavy or low-speed channellized traffic. With the aim to provide a guidance pertaining to combi-layers design, the Authors developed a research program for evaluating the performance of mixtures of asphalt concrete filled with cement mortar, produced using a soft modified bitumen and calcareous aggregates, adopting different particle size distributions.
