Wheel tracking test and ice pull-out test were performed in laboratory on dense grade asphalt mixture and asphaltmixture including 2.5% of 19mm PE aggregates. Meanwhile, temperature change, thermal conductivity, and snow meltingspeed were measured for both dense grade asphalt and PE aggregate mixed asphalt pavement via field testing on a testroad. Laboratory test results show that dynamic stability was improved and ice was removed easily by mixing PEaggregates in an asphalt mixture. Moreover, the existence of PE aggregates enhances heat insulation and snow meltingspeed due to the lower thermal conductivity compared to ordinary dense grade asphalt mixtures.
