- Abstract:
- Waste plastic is attempted to be reused in pavement engineering in this research. The purpose of the study is to probe the possibility of using waste plastic in asphalt mixture as a kind of modifier and try to find a way to solve the problem of the waste plastic disposal. High Density Polyethylene plastic bags obtained from supermarket were shredded into pieces and were added into asphalt mixture at three percentages of 2%, 5% and 8%. The corresponding control samples were also made and tested. Three different temperatures were used and the frequencies ranged from 0.1 Hz to 25 Hz in this dynamic modulus test. When compared with the test results of the control samples, dynamic modulus of almost all the plastic modified samples (except 4 results) are greater than those of the control samples’. No regular pattern is shown in the test results of the phase angle. Modified asphalt mixture with 2% plastic is of the greatest dynamic modulus and phase angle. Based on the test results, better performance under intermediate and high temperature can be anticipated for plastic modified asphalt mixture.
