Hill Gradients

Gradient / Hill Mu-split 10% to 30%

Our Mu Split Hills provide controlled split-friction conditions with gradients ranging from 10% to 30%. Each hill is typically 20–30 m in length, incorporating a 1 m wide ice strip alongside a heated, high-mu asphalt surface. Surfaces are meticulously prepared, with asphalt sections dried and maintained for consistency, and ice prepared to achieve a coefficient of friction of 0.1 Mu or lower. Both shared and exclusive booking options are available. All surfaces are continuously monitored and maintained to ensure precision, repeatability, and the highest-quality test conditions.
