Warm Mix Asphalt (WMA) technologies allow a reduction in the production and paving temperature of conventional Hot Mix Asphalt (HMA). However, not all of the techniques can provide similar asphalt performance as for HMA; therefore the WMA design process should involve not only empirical characterization of the asphalt but also analysis of bitumen and performance properties of the asphalt. The research presented in this paper involved evaluation of two warm mix asphalt additives – “Rediset WMX” and “Sasobit”. Rediset WMX is a chemical additive combining cationic surfactants and rheology modifier based on organic additives. Sasobit is a Fischer-Tropsch process wax that reduces the viscosity of bitumen above the melting point of wax (~90°C), thus improving the wetting of aggregates and workability of the mix.
