The aim of this paper is to analyse the suitability of recycled Waffle Pans polyurethane (PU) foam as a binder modifier in mastic asphalts (MA).The results show that harder bitumen is achieved with an increasing percentage of PU, up to 5 %, when the workability of the sample becomes poor.A MA mix with a 4 % of PU in bitumen was manufactured.

A lower indentation was observed when compared to a virgin sample, and it was established that the modified MA can be used on Tables - Over Bed Table heavy-traffic roads.These results suggest a promising use of this waste polymer.
