Utilization of Waste Polymers for Flexible Pavement and Easy Disposal of Waste Polymers
Traffic intensity is increasing, as are load bearing capacities of the roadways. Studies on the improvement of road strength using polymer modified bitumen for flexible pavement are being carried out by different schools. Virgin and recycled polymers are being used for these studies. However, when higher percentages of plastic wastes are used, the polymer becomes separated from the blend. Hence, a new innovative technique was developed by the authors and the heated stone aggregate was first coated with plastics generated from wastes like carry bags, films, foams, and multi layers and the plastics waste coated aggregate (PCA) was used as the raw material for flexible pavement. PCA is then mixed with 60/70 or 80/100 bitumen and the mix is used for road construction. PCA + bitumen mix showed better binding properties, had less wetting properties, and its voids were much less. The sample showed higher Marshall Stability value. By this process a road of 1km length and 3.75m width of single lane can consume 1,000,000 carry bags, road strength is increased by 100%, and there is no pothole formation. The roads laid using PCA + bitumen mixes are performing well. Performance studies were carried out for plastic road of different ages and are reported in this paper.
