Enhanced characterization of asphalt mix performance to support balanced mix design and climate-resilient sustainable pavement structures

该提案概述了马尼托巴省大学、马尼托巴省基础设施部、温尼伯市、Winpak Inc.和马尼托巴省研究中心之间的合作伙伴关系。虽然先进的沥青测试方法已经在研究实验室进行了多年，但这项合作研究包括开发和部署基于性能的沥青混合料测试方法，供道路运输机构及其咨询工程师和材料实验室在日常实践中使用。沥青测试的最新进展已经确定和研究了简单的测试工具，这些工具可以用来表征和预测路面性能，以提高道路结构的耐久性和可持续性。这些工具可以更好地控制已建道路设施的质量和一致性。通过将这些工具应用于实践，马尼托巴省将更新规范和设计方法，并将提高道路设计和施工及相关流程的可靠性。这些改进将对已建成基础设施的生命周期成本产生直接影响。此外，废塑料已被确定为一种潜在的有益的道路建设材料。该项目中新开发的工具将支持与Winpak和陶氏化学的研究，以开发和销售将废塑料作为沥青改性剂的技术。

This proposal outlines a partnership between the University of Manitoba, the Manitoba Department of Infrastructure, the City of Winnipeg, Winpak Inc, and Research Manitoba. While advanced asphalt test methods have been performed in research laboratory for many years, this collaborative research consists of development and deployment of performance-based asphalt mixture test methods for use in routine practice by road transportation agencies and their consulting engineers and materials laboratories. Recent advances in asphalt testing have identified and researched simple test tools that can be used to characterize and predict pavement performance to advance the durability and sustainability of road structures. These tools allow greater control over quality and uniformity of the constructed road facilities. By deploying these tools into practice, Manitoba will update specifications and design methods and will improve the reliability of road design and construction and associated processes. These improvements will have a direct impact on life cycle cost of built infrastructure. In addition, waste plastic has been identified as a potentially beneficial road construction material. The newly developed tools in this project will support research with Winpak and Dow Chemical to develop and market technology for incorporating waste plastic as an asphalt modifier.
