1.Introduction
尽管采取了一定的步骤来控制土地污染,但由聚乙烯废物引起的环境条件并没有太大变化(图1)。全球塑料的生产每年约为310吨,需要消费以防止进一步的环境损失。
About 1.15 km length of road covers 9000m2 of area, which requires about 600 tons of bitumen. Adding 50% polyethylene would allow us to give space for 300 tons of polyethylene. Shredded waste plastics may be used along with bitumen for road construction (Fig. 2).

2.Idea behind our work
The idea behind our project is to use optimized mixture ratio of polyethylene and bitumen with gravel in the construction of road instead of conventional mixture of bitumen with gravel (control).
通常,大约10%的沥青与90%的砾石(按重量)混合,以进行正常的道路建设。我们的想法着重于使用大约50-50个聚乙烯和沥青的混合物比,并在道路构造中进一步使用90%的砾石,以减少所谓的塑料污染的影响。
塑料砾石的韧性更多是只有沥青碎石,尽管弹性模量略微减少了塑料砾石(表1)。因此,我们的工作证明了在较低的道路维修成本下降低塑料污染而不会产生不良影响(即使在六个月后也没有扭曲修复的繁忙道路,也可以明显看出废塑料进行道路建设。
用砾石沥青 Polyethylene + Bitumen with gravel
Toughness: 4.3 kJ/m3
Modulus: 30.0 MPa
休息时伸长率:18.36%
拉伸强度:0.06 MPa
韧性:4.8 kJ/m3
Modulus: 21.3 MPa
Elongation at break: 30.54 %
Tensile strength: 0.05 MPa

Thus, our developed material demonstrate the efficacy of road repairing material where 50% waste plastic can be used which will reduce the plastic pollution along with lower cost of road repairing. This idea may be extended to road construction as well using waste plastic at large scale.
3. Repairing of road using waste polyethylene
Figure 3 shows images of the 'pothole' and 'filled pothole' by using mixture of polyethylene and bitumen with gravel at different time interval up to six months which clearly demonstrate that no pothole generated over the repaired pothole or in other words there is no damages on the repaired potholes and act like repaired with conventional bitumen treated road repairing. To understand the strength of plastic mixed bitumen against pure bitumen, tensile tests were performed with gravel mixture. Figure 4 shows the stress-strain curves of plastic filled construction materials vis-a-vis only bitumen filled gravel (control).
