1. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations
Abstract : 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. READ MORE

2. Analyses of Resilient Behavior of Unbound Materials for the Purpose of Predicting Permanent Deformation Behavior
Abstract : 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. READ MORE

3. Thaw Mechanism in Subgrades
Abstract : Freezing-thawing, changes the properties of soil due to the phase change of the water in the soil body. Freezing-thawing cycles in the soil have been studied for several decades including extensive laboratory research. In this study, the main focus is thawing based on laboratory investigation.

4. Mechanical Properties of Residues as Unbound Road Materials - experimental tests on MSWI bottom ash, crushed concrete and blast furnace slag
Abstract : For recycled aggregates and industrial by-products to beused correctly in road construction, it is necessary to knowtheir properties. Existing material specifications and testmethods for aggregates used in Sweden and in many othercountries are indirect and are based on empiricism. READ MORE

5. Investigation of the structural response of pavements in cold region using instrumented test site data
Abstract : The structural behaviour of pavement structures is known to be affected by the traffic-related loading and by the ambient factors to which the structure is subjected. A new mechanistic-empirical (M-E) pavement design method is under development in Sweden with the main purpose to adequately predict pavement structural response and performance. READ MORE
