  1. 1. Modeling pavement performance based on data from the Swedish LTPP database : predicting cracking and rutting

    Author : Markus Svensson; Helge Mork; Sigurdur Erlingsson; Statens väg- och transportforskningsinstitut; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cracking; Rutting wheel ; Prediction; Calculation; Mathematical model; Flexible pavement; Performance; Sprickbildning; Spårbildning; Förutsägelser; Beräkning; Matematiska modeller; Flexibla överbyggnader; Prestanda; 32 Road: Pavement design; 32 Road: Pavement design; performance predictions; LTPP; rut; crack; statistical modeling;

    Abstract : The roads in our society are in a state of constant degradation. The reasons for this are many, and therefore constructed to have a certain lifetime before being reconstructed. To minimize the cost of maintaining the important transport road network high quality prediction models are needed. READ MORE

    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance; Deformation; Model not math ; Rutting wheel ; Viscoelasticity; Elasticity; Axle load; Flexible pavement; Laboratory not an organization ; Test; Thesis; Heavy vehicle simulator; Wheel tracking test; Road: Pavement design; Road: Pavement design; Flexible Pavement; Pavement Performance Models; Multilayer Elastic Theory; Linear Viscoelasticity; Rutting; Accelerated Pavement Testing; Heavy Vehicle Simulator; Transportvetenskap; Transport Science; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : 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. 3. Influence of aggregates on permanent deformation of asphalt

    Author : Bernardita Francisca Lira Miranda; Robert Lundström; Stefan Larsson; Alan Carter; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt; deformation; rutting; gradation; flakiness index; Asfalt; kornstorleksfördelning; flisighetsindex; permanent deformation; spårbildning.; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : One of the most common failure modes for asphalt pavements is the occurrence of permanent deformation on the wheel path. This leads to not only other distresses, such as potholes and stripping, but also decreases substantially road safety and increases maintenance costs. READ MORE

  4. 4. Impacts of forestry operations on soil physical properties, water and temperature dynamics

    Author : Linnea Hansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Soil physical disturbances caused by forestry operations can be both intentional, e.g., soil scarification, and unintentional, e.g. READ MORE
