1. Mechanics-based Design Framework for Flexible Pavements
Sammanfattning : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This paper presents a mechanics-based design framework in load and resistance factor design (LRFD) format for the top-down fatigue cracking performance evaluation of flexible pavements. LÄS MER
2. Implementation and evaluation of an HMA fracture mechanics based design module
Sammanfattning : A thickness design module for flexible pavements, based on the HMA fracture mechanics framework, has been developed in order to design against premature failure caused by cracking. The HMA fracture mechanics based design module has been evaluated by designing typical Swedish pavements under typical Swedish climate and loading conditions and comparing the results with a reference design framework.

3. Internal Erosion Phenomena in Embankment Dams : Throughflow and internal erosion mechanisms
Sammanfattning : In this study, two major internal erosion initiation processes, suffusion and concentrated leak mechanisms, which lead to both defect formation in a dam’s body and its foundation and high throughflow in dams subjected to internal erosion were studied. This understanding has the potential to facilitate numerical modelling and expedite dam safety assessment studies. LÄS MER
4. On the quantification of healing in asphalt materials
Sammanfattning : Asphalt materials exhibit self-healing characteristics. In order to evaluate the healing capabilities of these materials, numerous investigations are carried out by researchers. These investigations include various definitions of healing and mechanical test methods to quantify the extent of healing. LÄS MER
5. Effects of manufacturing chain on mechanical performance : Study on heat treatment of powertrain components
Sammanfattning : The increasing demands for lightweight designs with high strength call for improved manufacturing processes regarding heat treatment of steel. The manufacturing process has considerable potential to improve the mechanical performance and to obtain more reliable results with less variation. LÄS MER
