The aim of the research was to evaluate the properties of foamed bitumen, produced from a Fischer-Tropsch synthetic wax modified 50/70 penetration grade bitumen for use as a binder in road construction layers. The binders were subjected to conventional tests (including penetration, softening point, Fraass breaking point and dynamic viscosity) as well as bitumen-foam-specific testing (including expansion ratio, half-life and foam index at different foaming water contents). Optimum amounts of foaming water and Fischer-Tropsch wax were identified and the binders were classified as relevant for different low-energy bitumen mix production techniques.
