MODIFIER COMPOSITION FOR WARM ASPHALT MIXTURE WITH PERFORMANCE GRADE OF MINIMUM 76-22 RANGE, PROCESS OF MANUFACTURING MODIFIED WARM ASPHALT MIXTURE BY USING THE SAME AND PROCESS OF MANUFACTURING COLOR WARM ASPHALT ROAD BY USING SAME

摘要

A modifier composition for warm asphalt mixture is provided to reduce fuel consumption while minimizing emission of harmful materials such as carbon dioxide and to lower optimal mixing temperature and optimal pressing temperature by 15~25 ‹C. A modifier composition for warm asphalt mixture is prepared by heating, melting and mixing, based on a polyamide-based polymer compound 100.0 parts by weight, a low density polyethylene resin 10~30 parts by weight, process oil 35~100.0 parts by weight and polyethylene wax 50~150 parts by weight. A method for manufacturing the modifier composition for warm asphalt mixture comprises a step of adding and mixing the modifier composition for warm asphalt mixture 2~8 parts by weight based on the asphalt 100.0 parts by weight.
