MANUFACTURING METHOD OF ASPHALT COMPOSITION AND PAVING MATERIAL FOR ROAD, WATERPROOFING MATERIAL FOR INDUSTRY THAT CONTAINS SAME

摘要

The present invention relates to a method for manufacturing a modified asphalt composition which comprises steps for mixing asphalt with a modifier, and making the same react with oxygen and, more specifically, to a method for manufacturing a modified asphalt composition which supplies 1-100 liters of oxygen with respect to 1 kg of modified asphalt compositions, and to a paving material for road and an industrial waterproofing material including the composition manufactured thereby. A modified asphalt binder manufactured according to the present invention: can simultaneously express excellent high temperature properties and low temperature properties; and can be manufactured at low temperatures, thereby minimizing energy consumption. In addition, the asphalt binder manufactured according to the present invention increases compatibility, thus phase separation is not generated even when the asphalt binder is stored for a long period of time.
