1. Efficient Winter Road Maintenance : A Study of Technical and Contractual Issues
Sammanfattning : Since ancient times, roads have tied people and cultures together. Roads have been createdwith the aim of facilitating trade and cultural exchange among different regions in the world. LÄS MER
2. Road profile statistics relevant for vehicle fatigue
Sammanfattning : Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). LÄS MER
3. On the influence of surface roughness on rolling contact forces
Sammanfattning : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.

4. Technical and contractual aspects in winter highway and railway operation and maintenance : a survey of current technical systems and contract forms in Sweden
Sammanfattning : .... LÄS MER
5. A Bayesian approach to retrospective detection of change-points in road surface measurements
Sammanfattning : First-order autoregressive processes are analysed for sudden changes in parameter value. In its most general form, a multivariate vector of measurements is allowed, and no prior knowledge about the involved parameters is required. LÄS MER
