Abstract: During the reconstruction of road pavements the reclaimed asphalt pavement (RAP), which is obtained through milling of the worn out existing asphalt, is commonly used for producing new base courses in cold recycling processes. Two of these techniques are most popular: one using mineral-cement-emulsion mixes (MCE) and one utilizing mineral cement mixes with foamed bitumen (MCAS). Additionally some amounts of RAP can be incorporated into traditional hot mix asphalt. The paper presents the possibility of using RAP for producing asphalt concrete in warm mix process (WMA) by the use of foamed bitumen modified with Fischer-Tropsch synthetic wax and a reference mixture produced in hot mix process for comparisons. The carried out analyses and tests shown that the experimental warm mix asphalt produced with RAP and foamed bitumen fulfilled the requirements for binding course asphalt concrete.
