Extreme climates, particularly in regions with both hot summers and cold winters (as in Canada), contribute substantially to premature failure of pavement structures. This problem is exacerbated by increases in the number and weight of truck traffic on the national highway system, as happened in the recent economic upturn. The combination of these two factors accelerates pavement deterioration and ultimately shortens the service life of flexible pavements in Canada. Furthermore, the pervasive generation of plastic waste has become a global concern during the past two decades, where Canada is also suffering from disposing of about 4 million tonnes of plastics in landfills annually. Therefore, innovative solutions are needed to reduce millions spent on pavement maintenance and rehabilitation, prevent excessive road work delays, and minimize the use of natural resources such as mineral aggregates and petroleum products (in turn minimizing environmental impacts of our road systems). The University of Waterloo's Centre for Pavement and Transportation Technology (CPATT) is at the forefront of innovation in these areas and aims to achieve more durable pavements designed for the Canadian climate. Our research focuses on recycling a portion of the plastics waste stream to produce polymer modified asphalt concrete, and prolong the service life of pavements and alleviate the environmental burden imposed by the waste plastics generation.In this study, researchers from CPATT will work with the experts from Peel Plastic Products Ltd., Steed and Evans Ltd., and Yellowline Asphalt Products to advance the reuse of waste plastic materials in asphalt modification. The main objective is to find the best way to incorporate waste plastics (polymers) into the asphalt mix. In addition, the optimum quantities of plastic materials will be determined from laboratory tests to achieve the best performance. Reusing waste plastics as an innovative construction material is a sustainable solution that can greatly benefit Canadians as it will not only help increase the roads service life, but also preserve the environment.

极端气候，特别是在夏季炎热和冬季寒冷的地区（如加拿大），大大有助于路面结构的过早失效。随着最近经济的好转，国家公路系统上卡车交通的数量和重量增加，这一问题更加严重。这两个因素的结合加速了路面的劣化，并最终缩短了加拿大柔性路面的使用寿命。此外，在过去二十年中，塑料废物的普遍产生已成为全球关注的问题，加拿大每年也要在垃圾填埋场处理约400万吨塑料。因此，需要创新的解决方案，以减少数百万美元的路面维护和修复费用，防止道路工程过度延误，并尽量减少对矿物骨料和石油产品等自然资源的使用（从而尽量减少我们的道路系统对环境的影响）。滑铁卢大学的路面和交通技术中心（CPATT）处于这些领域创新的最前沿，旨在实现针对加拿大气候设计的更耐用的路面。我们的研究重点是回收一部分塑料废物流来生产聚合物改性沥青混凝土，延长路面的使用寿命，减轻废塑料产生的环境负担。在这项研究中，CPATT的研究人员将与皮尔塑料制品有限公司的专家合作，斯蒂德和埃文斯有限公司，和Yellowline沥青产品，以促进废旧塑料材料在沥青改性中的再利用。主要目标是找到将废塑料（聚合物）掺入沥青混合料的最佳方法。此外，将通过实验室测试确定塑料材料的最佳数量，以实现最佳性能。将废塑料作为一种创新的建筑材料进行再利用是一种可持续的解决方案，可以使加拿大人受益匪浅，因为它不仅有助于延长道路的使用寿命，还可以保护环境。
