Pavement infrastructure represents a massive investment in Canada. Planning, designing, constructing, and managing cost effective, high quality road and airfield pavements is a major challenge to provinces, cities, municipalities and airport authorities. Climate change and associated extreme weather events, including flooding from intense rainfall and snowmelt, increased freeze thaw cycling and heatwaves have had a dramatic impact on pavement performance in Canada, resulting in rapid pavement deterioration, safety concerns and increased costs.  There is an urgent need to understand these impacts on Canadian pavement networks and to develop mitigation strategies, adaptive designs and innovative management techniques that produce safe long-life cost-effective pavement infrastructure. The vision of this research program is to develop novel resilient pavement designs and management tools, by using fundamental scientific findings, to improve pavement engineering in Canada over the next decade and beyond. This unique holistic approach which examines materials, design, and performance deals with all components of the pavement life cycle. The objectives of this Discovery grant include: investigating climate change and extreme weather impacts on pavement networks; developing deterioration models for pavement, examining engineered materials, designs and pavement treatments that improve understanding how advanced monitoring tools can be used to mitigate pavement damage, and determining adaptation strategies that provide technical, economic and environmental benefit for both current and future pavement networks. The overall research framework will use up-to-date loading and environmental information so that pavement can be designed or possibly retro-fit/adapted for long-life performance. The global relevance and potential for socioeconomic impact of this research is immense. If a pavement is going to achieve a longer in-service life, it must consider both loading and environmental impacts over that life cycle period. This involves better understanding of the current and future impacts of both the number and duration of freeze thaw cycles, precipitation quantities and changes in minimum and maximum pavement temperatures, as all these factors impact pavement performance.  Innovative novel pavement technologies that advance and extend pavement life with a strong emphasis on resiliency and usage of durable, long lasting materials will be a focus. The research will also utilize data and new methods/tools to develop realistic long-term performance models and will consider constructability of new designs/materials and innovative low cost monitoring methods. Practitioners and policy makers will benefit from this research through improved safety, serviceability, realization of improved cost effectiveness, the development of guidelines for better pavement design, sustainable usage of materials, and by adding highly skilled people to this field of research.

路面基础设施代表了加拿大的大量投资。规划，设计，建造和管理成本效益，高质量的道路和机场路面是对设施，城市，市政当局和机场当局的主要挑战。气候变化和相关的极端天气事件，包括降雨量和融雪，冰冻循环和热浪的增加对加拿大的路面性能产生了巨大影响，从而导致纸面迅速的定义，安全问题和成本增加。迫切需要了解这些对加拿大纸网络的影响，并制定缓解策略，自适应设计和创新的管理技术，从而产生安全的长期成本效益的纸质基础设施。该研究计划的愿景是通过使用基本的科学发现来开发新颖的弹性路面设计和管理工具，以在未来十年及以后改善加拿大的路面工程。这种独特的整体方法研究材料，设计和性能涉及人行道生命周期的所有组成部分。这项发现赠款的目标包括：调查气候变化和对路面网络的极端天气影响；开发人行道的定义模型，检查工程材料，设计和路面处理，以提高理解如何使用高级监控工具来减轻路面损害，并确定适应策略，这些策略为当前和未来的人行道网络提供技术，经济和环境效益。总体研究框架将消耗最新的加载和环境信息，以便可以设计或适应可能的恢复性/可能的长期性能。这项研究的全球相关性和对社会经济影响的潜力是巨大的。如果人行道要实现更长的服务寿命，则必须考虑在该生命周期期间的负载和环境影响。这涉及对冻结周期的数量和持续时间的当前和未来影响更好地理解，因为所有这些因素都会影响路面性能，降水量和最低和最高路面温度的变化。创新的小说小说技术，旨在提高和延长路面寿命，重点是弹性和使用持久，持久材料的使用，这将是重点。研究还将利用数据和新方法/工具来开发现实的长期绩效模型，并将考虑新设计/材料和创新的低成本监控方法的构造性。从业人员和政策制定者将通过改进的安全性，可维护性，提高成本效益的实现，更好的路面设计指南，材料的可持续使用以及在这一研究领域中添加高技能的人，从而从这项研究中受益。
