Track 1: Plateau Area – Wet Braking
Overview
In addition to dry testing surfaces, Track One also contains two very important wet test areas. The first is the plateau, which offers precise water depth controls and four driving lanes (A1, A7, A8 & A9), each with different grip levels. This is used for testing wet braking.
Dimensions
- A1: 12.8 feet x 246 feet
- A7: 9.4 feet x 246 feet
- A8: 16 feet x 328 feet
- A9: 16 feet x 492 feet
Surfaces / Surface Textures (Macro/Micro) / Aggregate
- A1: Concrete / Smooth / Smooth / N/A
- A7: Asphalt / Rough / Smooth / Limestone
- A8: Sand Asphalt / Smooth / Smooth / Granite
- A9: Asphalt / Rough / Smooth / Limestone
Usage / Features
- Wet braking and wet traction testing
- Standard water depth for adherence plateau is 1.2mm
- A1: IRI = 38.9 in/mile
- A8: IRI = 68.1 in/mile
