11. Characterising the Deformation Behaviour of Unbound Granular Materials in Pavement Structures
Sammanfattning : Unbound granular materials (UGMs) used in the base and sub-base layers of flexible pavements play a significant role in the overall performance of the structure. Proper understanding and characterization of the deformation behaviour of UGMs in pavement structures are, therefore, vital for the design and maintenance of flexible pavements. LÄS MER
12. 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
13. 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
14. Post-failure behaviour of brittle rock
Sammanfattning : The study of the post-failure behaviour of brittle rocks in the laboratory needs stiff and servo-controlled testing machines. Yet, the problem is not completely solved unless a suitable feedback signal is created for the servo-loop of the testing machine. LÄS MER
15. Ground Improvement by Dry Deep Mixing Lime-Cement Column Panels as Excavation Support
Sammanfattning : Many urban areas near the coastal regions of Sweden are characterized by post-glacial clay deposits with very low undrained shear strength and high compressibility. Column type ground improvement by the Deep Mixing, DM, method using a binder mixture of lime and cement is commonly used in areas with poor soil conditions due to its cost-effectiveness, predominantly for settlement reduction and to improve the stability of embankments.
