CHARACTERISATION OF RECYCLED POLYETHYLENE

As far as the data was concerned, the additional replacement of recycled PET as fine aggregate in asphalt mixture could decrease the value of stiffness modulus of asphalt mixture. For example, the stiffness modulus value of bitmen content 4.5% for 0% and 25% PET modified asphalt mixture were 2600MPa and 1600MPa, respectively. In bitumen content aspect, all PET modified asphalt mixture obtain more stiffness modulus at 5.5% bitumen content of weight of asphalt mixture. The result also shows the highest value stiffness modulus of 0% PET modified asphalt mixture reached at 5.5% bitumen content. This graph shows the additional replacement recycled PET as partial affine aggregate in asphalt mixture could not help improve the stiffness of modified asphalt mixure. However this result is same with another study that have been done about the stiffness of recycled plastic like low density polyethylene (LDPE) and high density polyethylene (HDPE) as aggregate replacement on asphalt
