Testing has been performed in a number of soils including high organic soils (peat), silts, sands, gravels, and lunar regolith at various moisture contents. A data set containing derived strength parameters is being built and results that are non-proprietary and non-controlled are shared with permission on the KRC website. KRC has also performed several vehicle mobility tests both in the field and in the lab on the KRC single wheel tire tester. A large amount of this collected data is also available on the website with permission. All testing includes cone penetrometer, nuclear density, moisture, and surface friction when possible. This paper will be an overview of the Bevameter and the data collected to date, as well as an overview of other mobility testing that has been performed. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://2025.istvs.org/submissions/papers/6540.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
