PREPARATION METHOD OF ASPHALT CONCRETE

摘要

PURPOSE: A preparation method of asphalt concrete using stainless steel slag as aggregate is provided, which exhibits excellent dynamic stability and similar asphalt stability against water in comparison with the case using only sand as aggregate. CONSTITUTION: An asphalt concrete using stainless steel slag as aggregate is characterized by incorporating 6-12 wt.% of stainless steel slag and 0-6 wt.% of sand, and 5.5-6.5 wt.% of asphalt, based on the weight of asphalt concrete, further the volume of stainless steel slag and sand is 12 wt.% based on the total volume of asphalt concrete.
