项目摘要

This research program aims to develop a new and fully mechanistic pavement design method that is based on finite element modeling. The design method uses the software PSIPave3D, which was developed by PSI Technologies Inc. The research compares this software to pavement design methods that are commonly used across Canada. These existing methods are largely empirically-derived, which means that their application to Canadian conditions can often be questionable. Mechanistic design considers the actual behaviours of the constituent materials and conditions of the site to provide a real prediction of the pavement structure's performance. Additionally, the research involves the development of a laboratory procedure for characterizing pavement construction materials in a way which can be implemented into PSIPave3D. Subsequently, common paving and subgrade materials will be characterized and incorporated into a materials database which will make the software more widely applicable. The selection of common pavement materials will be performed via the distribution of a survey to various practitioners throughout Canada, inquiring about their typical materials and conditions. Finally, analysis of existing sections will be performed and compared to the results of a PSIPave3D design as a verification. The result of this research will be a pavement design tool which will be applicable across Canada and will provide pavement designers with meaningful mechanistic analysis of their pavements.

该研究计划旨在开发一种基于有限元建模的新的，完全机械的路面设计方法。该设计方法使用PSI Technologies Inc.开发的软件PSIPAVE3D。该研究将该软件与通常在加拿大常用的路面设计方法进行了比较。这些现有的方法在很大程度上是经验衍生的，这意味着它们在加拿大条件上的应用通常可能值得怀疑。机械设计考虑了站点的组成材料和条件的实际行为，以提供人行道结构的性能的真实预测。此外，该研究涉及开发实验室程序，该程序以可以在PSIPAVE3D中实施的方式来表征路面建筑材料。随后，将将常见的铺路和子分级材料进行表征并纳入材料数据库中，该数据库将使软件更广泛地适用。选择常见的路面材料将通过向整个加拿大的各个从业人员分发进行调查，询问其典型材料和条件。最后，将对现有部分进行分析，并将其与PSIPAVE3D设计的结果进行比较。这项研究的结果将是一个路面设计工具，该工具将在整个加拿大适用，并将为路面设计师提供对人行道的有意义的机械分析。
