1. Computational Road Mechanics - with Emphasis on FE-analysis of Rutting
Sammanfattning : A road is a very complex structure in which a large number of different structural phenomena occur simultaneously that effects its expected lifetime. The structure itself is of a multi-layer type, in which the different layers consist of materials that exhibit vastly different physical behaviors when subjected to various kinds of loads. LÄS MER
2. Analyses of Resilient Behavior of Unbound Materials for the Purpose of Predicting Permanent Deformation Behavior
Sammanfattning : Post compaction is the unintended compaction of the unbound material that commences immediately after a road is brought into service and caused by densification of the material. Analogies to this post compaction can also be seen in laboratory and field tests. LÄS MER
3. Fatigue of unbound material in a road structure
Sammanfattning : .... LÄS MER
4. Performance model for unbound grnular materials pavements
Sammanfattning : Recently, there has been growing interest on the behaviour of unbound granular material in road base layers. Researchers have studied that the design of a new pavement and prediction of service life need proper characterization of unbound granular materials, which is one of the requirements for a new mechanistic design method in flexible pavement.

5. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations
Sammanfattning : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. LÄS MER
