LOW-CARBON EMISSION WARM-MIX ASPHALT(WMA) MIXTURE USING LIQUID-TYPE WMA ADDITIVE, AND MANUFACTURING METHOD FOR THE SAME

摘要

As a chemical additive added to the medium temperature asphalt mixture (WMA), a small amount of the weight of the asphalt, for example, 0.2 to 5% by weight of the liquid type medium temperature additive, can reduce the cost, and the low carbon material using the liquid type medium temperature additive with excellent performance A medium temperature asphalt mixture and a method for producing the same are provided. The low carbon mesophilic asphalt mixture using the liquid mesophilic additive is prepared by mixing 0.2 to 5.0% of the liquid mesophilic additive with respect to the weight of the aspha And liquid phase neutralizing additive, 45-97.5wt% liquid base oil; 0.5-7 wt% of reduced pressure light fraction (VHGO) added for viscosity performance and compaction performance with application of the mixture; A viscosity index improver (VMS) of 0.5-12 wt% added to minimize the change in viscosity due to the change in temperature and to reduce the change in viscosity; 0.5 to 12 wt% asphalt modifier added to increase the hardness of the aspha 0.5-12 wt% of an anti-peeling agent (ASA) added to exhibit a function of anti-peeling while maintaining without changing the properties of the medium-temperature asphalt mixture (WMA); And 0.5 to 12 wt% of surfactants, and the liquid neutralizing additive uses 0.2 to 5 wt% of the weight of asphalt, and the base oil is a hydro-treated heavy paraffinic distillate oil. Can be.
