| Abstract | ||||
| Global attention is paid to construct eco-friendly road in both advanced countries and Developing countries. It's increased due to the increased demand and to decrease the harmful impacts of road construction also to green our basic substructure. Therefore, plastic waste were collected and sorted from different dumps of garbage. Then high-density polyethylene (HDPE) wastes were chosen for doing different tests. Replacement of aggregates by dry plastic in asphalt mixes was done with 6%, 8%, 10%, 12% and 14%. Mixtures containing shredded (HDPE) showed improvement with respect to the Marshall stability and flow properties. Laboratory aging procedures have been set up to simulate the ageing process at 90 °C oven for (24h, 72hr). Finally it could improve the level of performance and the service life of the road. It can be sum up that the High Density Poly Ethylene (HDPE) modified asphalt mixture gives more advantages compared to the traditional one. Having considered the environmental and economic features, the modified asphalt mixture at 12% is found suitable to be used for road pavements. It’s found that plastic mixture significantly improve the mechanical properties and performance of asphalt mixture .Compared with traditional mixture, the HDPE modified mixtures had higher resistance of water susceptibility, where the indirect tensile strength test (ITS) results values for the modified mixtures had higher value than the traditional mixtures. T, asphalt samples made of replaced plastic aggregates gives lower densities results with increasing plastic aggregates percentage. | ||||
