Modification of a 14mm Asphalt Concrete Surfacing Using RAP and Waste HDPE Plastic

This paper reports the findings of a laboratory investigation to assess the use of waste high-density polyethylene (HDPE) plastic and recycled asphalt pavements (RAP) to improve the performance of a 14mm asphalt concrete (AC) surfacing. Waste HDPE plastic obtained from plastic milk cartons was blended with 60/70 penetration grade bitumen and its addition evaluated using the Softening Point test and modified Penetration test at 25°C, 30°C, 35°C and 40°C. This found the addition of waste HDPE plastic to increase softening point and lower penetration value. Deformation and fatigue testing of a 14mm asphalt concrete mix surfacing mix incorporating a blend of waste HDPE plastic and RAP was carried out at a range of test temperatures. This found that modification using waste HDPE plastic and RAP improved both deformation and fatigue properties. The laboratory investigation has shown that the use of waste HDPE plastic derived from milk containers combined with RAP could improve the performance of asphalt concrete subjected to heavy trafficking at higher ambient temperatures.
