Unpaved runway strength correlation

拟议的工作旨在编目通过Udarnik U-1 DropHammer和波音高负荷锥形穿透仪测试报告的值之间的关系。成功定义的关系将允许继续使用Udarnik U-1测试，同时安全准确地根据加州承载比（CBR）报告未铺砌跑道的强度。主要的潜在挑战是全球使用的未铺路材料的高度可变性。报告值之间的关系可能因不同的材料、水分含量和压实水平而异。为了解决这个问题，将记录并选择各种具有代表性的跑道材料样品进行测试。样品将在实验室中以不同的水分含量和压实水平制备，以保证溶液的坚固性。测试将使用Udarnik U-1落锤和波音高负荷conepometer进行，并对结果进行分析。项目方法学将为两种测试方法之间的关系提供一个健壮的解决方案。这将允许将解决方案应用于各种跑道，从而允许进入更广阔的市场。每两周一次的会议将由研究小组和公司人员的代表参加。会议主题可能包括进度更新、故障排除、反馈等。交付物应包括：当前实践总结，包括测试方法、跑道建设和维护标准、材料标准和样品制备标准；实验设计总结；结果总结；/位关系模型;以及最终的项目技术报告。庞巴迪将为该大学提供这两种测试设备的使用，以进行研究。此外，公司人员将参与每两周一次的会议，以监督项目进展，并在需要时提供澄清和输入。

The proposed work aims to catalogue the relationship between the values reported via the Udarnik U-1 DropHammer and the Boeing High Load Cone Penetrometer tests. The successfully defined relationship will allowcontinued use of the Udarnik U-1 test while safely and accurately reporting unpaved runway strength in termsof California Bearing Ratio (CBR). The principle underlying challenge is the high variability in unpavedrunway materials used across the globe. The relationship between reported values may vary across differentmaterials, moisture contents, and compaction levels.To resolve the problem, various representative runway material samples will be documented and selected fortesting. Samples will be prepared in lab at various moisture contents and compaction levels for robustness ofsolution. Testing will be conducted using both the Udarnik U-1 Drop Hammer and the Boeing High Load ConePenetrometer, and the results will be analyzed for significance. The project methodology will provide a robustsolution for the relationship between the two test methods. This will allow application of the solution to a widevariety of runways and will therefore allow access to broader markets.Bi-weekly meetings will be held with representatives from both the research group and company personnel.Meeting topics may include progress updates, trouble shooting, feedback, etc. Deliverables shall include: asummary of current practices including test methods, runway construction and maintenance standards, materialstandards, and sample preparation standards; summary of experimental design; summary of results; summaryof relationship/model; and the final project Technical Report.Bombardier will provide to the university the use of both pieces of testing apparatus for the purposes ofconducting the research. Further, company personnel will be involved in bi-weekly meetings to monitor projectprogress and provide clarifications and input as needed.
