项目摘要
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.
路面基础设施是加拿大的一项巨额投资。规划、设计、建设和管理具有成本效益的高质量道路和机场路面是各省、市、直辖市和机场当局面临的重大挑战。气候变化和相关的极端天气事件,包括强降雨和融雪造成的洪水、冻融循环增加和热浪,对加拿大的路面性能产生了巨大影响,导致路面迅速恶化、安全问题和成本增加。 迫切需要了解这些对加拿大路面网络的影响,并制定缓解策略、适应性设计和创新管理技术,以生产安全、长寿命、具有成本效益的路面基础设施。 该研究计划的愿景是利用基础科学发现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检查材料、设计和性能,涉及路面生命周期的所有组成部分。该发现拨款的目标包括: 调查气候变化和极端天气对路面网络的影响;开发路面恶化模型,检查工程材料、设计和路面处理,以提高对如何使用先进监测工具减轻路面损坏的理解,并确定适应策略,为当前和未来的路面网络提供技术、经济和环境效益。整体研究框架将使用最新的载荷和环境信息,以便可以设计路面或可能对其进行改造/调整,以实现长寿命性能。 这项研究的全球相关性和社会经济影响的潜力是巨大的。如果路面要实现更长的使用寿命,则必须考虑该生命周期期间的载荷和环境影响。这涉及更好地了解冻融周期的数量和持续时间、降水量以及最低和最高路面温度的变化对当前和未来的影响,因为所有这些因素都会影响路面性能。 创新的路面技术将成为焦点,这些技术可提高和延长路面寿命,重点强调弹性和耐用、持久材料的使用。该研究还将利用数据和新方法/工具来开发现实的长期性能模型,并将考虑新设计/材料的可施工性和创新的低成本监测方法。从业者和政策制定者将从这项研究中受益,包括提高安全性、适用性、提高成本效益、制定更好的路面设计指南、材料的可持续利用,以及向这一研究领域吸纳高技能人才。
