Performance and environmental assessment of the warm bituminous mixes with aspha-min

Since 2004 more than 430.000 tons of warm bituminous mixes have been applied in Europe and overseas. The object of this communication is to give a progress report on the behaviour of these bituminous mixes implemented on motorways (since 2003) on national roads, departments or in cities, as well in surface and base courses, with pure or modified bitumen. Clear results on the energy savings and emissions in the atmosphere have been obtained from measurements taken on asphalt mix plants. Also emissions measurements were carried out on site. The improvement to the workability of the warm bituminous mixes due to the aspha-min has made it possible to extend the period of application in late season. Thus bituminous mix with high modulus was applied at a temperature of about 5degreesC with mechanical characteristics (voids, modulus and fatigue) identical to those of a bituminous mix laid under normal conditions (15degrees).
