I. OBJECTIVES
1. Obtain better understanding of different runway friction measurement procedures and factors influencing tire/runway friction performance.
2. Expand existing friction measuring vehicle correlation to include new devices.
3. Provide opportunity to observe new test and pavement treatment equipment in operation.
4. Evaluate different pavement roughness measuring devices
5. Identify methods to improve harmonization between different measurement devices and test procedures used throughout the world
