چکیده
Worldwide the broad usage of plastic has resulted in the massive production of plastic pollution, which is incinerated, and put in landfills and oceans. The technique of coating road aggregate with plastic has a good potential to deal with this global issue. The unique physical, mechanical and thermal properties of polymer offers effective binding, less moisture retention, and less susceptibility to void formation. This research will ultimately reflect plastic waste management and road enhancement. The main purpose of this experimental study is to predict and highlight the effect of varying plastic composition coating on an aggregate and select the best-performing sample. For this study, samples of polymer-coated aggregates of different ratios are created, and further tested for their enhancement in properties. To create polymer-coated aggregate, we have used recycled aggregates, Grade ۷۰ bitumen, and polyethylene bags from waste. To coat the aggregates used the "dry-mix process". The effectiveness of the coating with varying plastic compositions was measured using seven different tests. It was hypothesized that incorporating plastic would enhance the properties of aggregate and increase the durability and workability of road materials. The test results supported the hypothesis. Standard ranges were used to perform a comparative study between polymer-coated aggregate and conventional aggregate. Nearly all tests' plastic compositions> ۸% and less than ۱۵% have shown good results, but the optimum value for all tests is achieved by a sample with ۱۲% plastic coating. Although this study supports that plastic incorporation is a better idea to enhance the longevity of roads, more research is required to explore the underlying mechanism of plastic coating and its long-term outcomes.کلیدواژه ها
