6. Packing theory-based Framework for Performance Evaluation of Unbound Granular Materials
Sammanfattning : Enhancing the load bearing quality of granular layers is fundamental to optimize the structural performance of the pavements. Unbound granular materials are one of the most used materials in the base layers of pavements. There have been growing interests on the behavior of unbound granular material in road base layers.

7. Influence of Water on Coarse Granular Road Material Properties
Sammanfattning : Even though the practical experience of using coarse unbound granular materials is extensive, detailed knowledge on the mechanical and hydraulic behavior is to a large extent lacking. Regarding influence of water on mechanical properties, this is even more pronounced. LÄS MER
8. 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
9. Investigation of the structural response of pavements in cold region using instrumented test site data
Sammanfattning : 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. LÄS MER
10. Resilient and permanent deformation behavior of unbound aggregates under repeated loading
Sammanfattning : During recent decades, growing interest in the developmentof so-called analytical or mechanistic road pavement designmethods has resulted in substantial research into themechanical behavior of the materials involved. In flexiblepavements, especially when unsurfaced or thinly surfaced,overall structural performance is largely dependent on thebehavior of the unbound granular base and subbase layers. LÄS MER
