STUDIES OF TYRES ON ROADS HAVING WET AND DRY SURFACINGS

UNDERSOEKNING AV DAECK - VAEGBANA MED AVSEENDE PAA OLINKA VAEGBELAEGGNINGAR

Measures taken to cut road traffic noise mainly concern engine noise, but tyre noise above 50 km/h contributes to a large proportion of total noise. The results of tests performed at 70 km/h on 6 test surfacings indicate that, in dry conditions, there is a difference of about 2 db(a) between the "best" and "worst" surfacing, while a wet surfacing is about 3 db(a) noisier than a dry one. There is negligible difference between surfacings in wet conditions. It does not appear that there is any difference between cross-ply and radial tyres. /TRRL/
