Pavement Performance in Cold Regions and Application of Insulation Layers

由于环境因素和交通负荷，加拿大最寒冷地区的道路恶化速度超过了维修可以防止的速度。公路机构现在面临着系统老化、可维护性降低和维护成本增加的问题，而用于道路维修的资金每年都在增加。大量的研究已经解决了温暖到温和气候下的路面工程问题，但这些结果不能适用于加拿大的寒冷地区。因此，我正在研究寒冷气候对路面性能的影响，并测试在道路建设中利用废物和回收材料的可行性。我提出的在寒冷地区的路面性能和保温层的应用程序将提供这些领域的进一步进展。****该项目的目标包括提高人们对寒冷地区环境因素和交通负荷对路面性能影响的认识水平；开发寒区路面材料长期性能综合数值模型；评估废物和再生材料作为绝缘路面材料在加拿大道路系统中的应用。****为了实现上述目标，我将开发一个实验室项目来研究受控冻融条件下路面材料的性能，并开发一个综合项目来研究受控实验室条件下保温材料的有效性。我还将利用一个全面的现场监测系统来调查寒冷地区路面材料的特性和性能。****我希望这项研究的成果将改善加拿大寒冷地区的路面状况和使用寿命，并促进再生/废物材料在道路行业的使用，从而为加拿大道路机构和加拿大纳税人节省大量资金。研究用于道路建设的废料也将增加道路基础设施的可持续性，从而保护加拿大的环境。这项研究的结果将发表在各种期刊和技术会议上，并将转交给加拿大各地的其他运输机构进行评估和实施

Due to environmental factors and traffic loading, roadways in Canada's coldest regions are deteriorating faster than maintenance can prevent the damage. Road agencies are now facing aging systems with lower serviceability and higher maintenance costs, with increased funding put toward road repair each year. An extensive amount of research has addressed pavement engineering issues in warm to moderate climates, yet these results cannot be applied to Canada's cold regions. I am therefore investigating the impact of cold climates on pavement performance, as well as testing the feasibility of utilizing waste and recycled materials in road construction. My proposed Pavement Performance in Cold Regions and Application of Insulation Layers program will provide further advances in these fields.****The program's goals include advancing the state of knowledge regarding the impact of environmental factors and traffic loading on pavement performance in cold regions; developing comprehensive numerical models for the long-term performance of pavement materials in cold regions; and evaluating the application of waste and recycled material as insulation pavement material in Canada's road system. ****To fulfill the aforementioned goals, I will develop a laboratory program to investigate pavement material properties under controlled freeze-thaw conditions and a comprehensive program to investigate insulation material effectiveness under controlled laboratory conditions. I will also utilize a comprehensive field monitoring system to investigate the properties and performance of pavement material in cold regions.****I expect that the outcomes of this research will improve pavement condition and service life in Canada's cold regions and promote the use of recycled/waste materials in the road industry, resulting in tremendous savings for Canadian road agencies and therefore Canadian taxpayers. Studying waste materials for use in road construction will also increase the sustainability of road infrastructure, thereby preserving Canada's environment. Findings from this study will be published in various journals and technical conferences and will be transferred to other transportation agencies across Canada for evaluation and implementation.**
