Abstract:
The tyre-road interaction is responsible for many tyre and road
'characteristics' like rolling resistance, noise, hydroplaning and wet grip.
In the EC legislation R1222 the 'tyre characteristics' are measured using
'standard roads'. Whearas 'road characteristics' like noise in the ISO 11819-
2 and skid resistance are often measured using 'standard tyres'. As the
standards are often old technology, real innovative steps are hard to achieve.
Therefore the project 'Stil Veilig Wegverleer' is started, translated as
'Silent and Safe Roadtraffic', where the tyre-road interaction is studied in
more detail regarding noise and wet grip. With new developed simulation and
test methodogies the tyre-road combination is optimized. An overview of the
project and the first results will be given.
