Abstract: The article presents the results obtained from testing of asphalt concrete with foamed bitumen produced and compacted at lowered temperatures. The basic physical characteristics along with moisture resistance and stiffness moduli performance in different testing temperatures of a total of three mixes are shown. A reference hot-mix is compared with two low temperature mixes: one based on neat 50/70 bitumen and a second based on a Fischer-Tropsch wax modified binder. The results show that it is possible to produce a low temperature mix that is performing as well as the reference mixture
