1. Municipal street pavement maintenance and management practices in Sweden
Sammanfattning : A well-functioning street network is pivotal in the socio-economic development of a region. Street networks not only facilitate the movement of people and goods but also allocate space for utility services. LÄS MER
2. Mechanistic-Empirical Modelling of Flexible Pavement Performance : Verifications Using APT Measurements
Sammanfattning : Mechanistic-Empirical (M-E) pavement design procedures are composed of a reliable response model to estimate the state of stress in the pavement and distress models in order to predict the different types of pavement distresses due to the prevailing traffic and environmental conditions. One of the main objectives of this study was to develop a response model based on multilayer elastic theory (MLET) with improved computational performance by optimizing the time consuming parts of the MLET processes.

3. Ground vibrations due to pile and sheet pile driving : influencing factors, predictions and measurements
Sammanfattning : Ground vibrations due to pile driving are part of a complex process. Vibration is generated from the pile driver to the pile. As the pile interacts with the surrounding soil, vibrations are transferred at the pile-soil interface. The vibration propagates through the ground and interacts with structures, both above ground and underground. LÄS MER
4. Cycle paths’ degradation processes and surface condition assessment
Sammanfattning : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. LÄS MER
5. Excavation in moraine and dense non-cohesive soil : Numerical analysis of soil behavior
Sammanfattning : Excavation and moving of soil are common civil work tasks connected to the construction of buildings, roads and railways. In construction projects large amounts of soil have to be handled with different machines, tools and working methods. Soils are more or less difficult to excavate depending on their properties.
