1. 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
2. Surface Wave Testing of Pavements
Sammanfattning : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. LÄS MER
3. 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
4. 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
5. Climate impact on the durability of asphalt concrete
Sammanfattning : Roads are subjected to traffic loads and varying climate conditions that eventually lead to different types of damage. Moisture in asphalt is one of the major causes of premature failure in asphalt pavements. LÄS MER
