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.

拟议的工作旨在对通过Udarnik U-1落锤和波音高载荷圆锥贯入仪测试报告的值之间的关系进行编目。成功定义的关系将允许继续使用Udarnik U-1测试，同时安全准确地报告未铺砌跑道强度的加州承载比（CBR）。挑战的根本原因是地球仪使用的未铺筑路面材料的高度可变性。报告值之间的关系可能因不同的材料、含水量和压实程度而异。为了解决这个问题，将记录各种有代表性的跑道材料样品，并选择这些样品进行测试。将在实验室中制备不同含水量和压实水平的样品，以确保溶液的耐用性。将使用Udarnik U-1落锤和波音高载荷圆锥贯入仪进行测试，并对结果进行显著性分析。该项目方法将为两种测试方法之间的关系提供一个强大的解决方案。这将允许将解决方案应用于各种各样的跑道，从而允许进入更广阔的市场。研究小组和公司人员的代表将每两周举行一次会议。会议主题可能包括进度更新、故障排除、反馈等。会议内容应包括：当前实践的总结，包括试验方法、跑道建设和维护标准、材料标准和样品制备标准;试验设计的总结;结果总结;关系/模型总结;以及最终项目技术报告。庞巴迪将向大学提供两种测试设备的使用情况，以便进行研究。此外，公司人员将参与每两周一次的会议，以监控项目进度，并根据需要提供澄清和输入。
