From texture to braking deceleration
conference paper
Nowadays its becomes more and more important to combine safe and comfortable mobility to a safe and liveable environment. For many decades the structural aspects of road constructions have been the subjects of many research activities. Only since the late 80's surface characteristics have been researched in order to give the pavement designer the appropriate tools to fulfil his task in an adequate way.
Also in The Netherlands where in 1983 the CROW-workgroup of Surface characteristics started an extensive research to establish the relations between road-tyre-vehicle interactions and Surface Characeristics. Preliminary results of this research have been presented at former congresses.
This paper presents the continuation of the development in which the conceptual model has been replaced by a first release model. Further the validity-range of the model has been extended to a large range of road micro and macro-textures.
The accuracy of this model is reasonable but the understanding of the error-sources shows that there is room for further improvements. After the final accuracy is expected to be in the range of 25% of the real braking performance of cars.
