Abstract :
Plastics industry have many major developments in the last two decades resulted from the increased utilization of plastics in various sectors. One of the most common used plastics is the thin plastic bags which used usually for packaging. However the disposal of the waste plastic bags in large quantities constitutes a real environmental problem. Hence, recycling waste into useful products is considered one of the most sustainable solutions to this crisis so that research into new and innovative uses of waste materials is continuously advancing. This paper studies the Compressive Strength of Plastic Waste Bituminous Concrete for Road Construction. The plastic waste was added to the bituminous concrete in increasing percentage and Marshall Samples were prepared. These samples were tested for compressive strength at 25°C and 60°C i.e unconditioned and conditioned samples. It is observed that the compressive strength of sample significantly increases up to 8%, 6% and 12% for dry process, wet process and combined process respectively for LDPE and HDPE type of waste plastic.
