Abstract
This paper sets out to investigate the effects Australian spray sealed road surfaces have on a vehicle with regards to an ever increasing requirement for reductions in road noise levels and the stated design advantage that spray sealed surfaces offer superior wet skid resistance. Using road surface texture, cabin sound pressure level and tyre friction data from various sealed surfaces investigations were conducted into identifying firstly the existence of any special relationships between texture frequencies and cabin sound pressure levels, and secondly the wet braking performance and skid resistance of three different tyre types.
