WMA with 35% of RAP and a mix additive of wax combined with fibres is a satisfactory material. The studied WMA blends revealed lower water sensitivity. Unlike WMA without RAP, stiffness of blends with RAP showed high sensitivity to porosity. Wax and cellulosic fibres increased resistance to rutting as compared to WMA with chemical additive. Production of WMA with a high RAP percentage is feasible by applying conventional means.
