如今，塑料垃圾的处理是一个世界性的问题，因为它的数量和增长相当大。解决这个问题的一个选择是回收这些废物。这种替代方法减少了净丢弃物的数量，节约了材料和能源，并提供了一种相对简单的方法来大幅度减少固体废物的总量。本研究的目的是通过比较实验室研究，探讨一种环境友好的方法，即通过在沥青混合料中添加不同百分比的城市和农村塑料废物，在干燥过程中回收它们的影响。考虑其体积参数和各种实验室力学试验的值，对所得混合物进行了分析。对未改性和改性热沥青混合料进行了马歇尔稳定性、马歇尔商、间接抗拉强度、断裂能、弹性模量、永久变形和蠕变柔度等性能试验。本文对所得结果进行了介绍和讨论，表明再生塑料在沥青混合料中的再利用是一种可行的替代方法，有助于减少塑料废物和保护环境。
Nowadays, the disposal of plastic waste is an issue of major concern worldwide because of its considerable volume and growth. An option to tackle this problem is to recycle this waste. This alternative reduces the quantity of net discards, conserves both material and energy and provides a comparatively simple way to make a substantial reduction in the overall volume of solid waste. The purpose of this study is to investigate an environmentally friendly approach about the influence of recycling different percentages of urban and rural plastic waste by adding them in a dry process on an asphalt mixture, through a comparative laboratory study. The resulting mixtures are analyzed considering their volumetric parameters and the values from diverse laboratory mechanical tests. The performance tests include, Marshall stability, Marshall quotient, indirect tensile strength, fracture energy, resilient modulus, permanent deformation and creep compliance, which were carried out on unmodified and modified hot asphalt mixtures. The obtained results are presented and discussed in this paper showing that the reuse of recycled plastics in asphalt mixtures is a viable alternative that contributes to the reduction of plastic wastes as well as the protection of the environment.
