1. Greenhouse Gas Fluxes and Carbon Sequestration in Young Norway Spruce Stands : The Effects of Fertilization
Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER
2. Modeling pavement performance based on data from the Swedish LTPP database : predicting cracking and rutting
Sammanfattning : 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. LÄS MER
3. Gradation-Based Framework for Asphalt Mixtures
Sammanfattning : Asphalt mixture microstructure is formed by aggregates, bitumen binder and air voids. Aggregates make for up to 90% of the mixtures volume and the structure formed by them will depend mostly on their size distribution and shape. LÄS MER
4. A Bayesian approach to retrospective detection of change-points in road surface measurements
Sammanfattning : First-order autoregressive processes are analysed for sudden changes in parameter value. In its most general form, a multivariate vector of measurements is allowed, and no prior knowledge about the involved parameters is required. LÄS MER
5. Rut Depth Prediction on Flexible Pavements - Calibration and Validation of Incremental-Recursive Models
Sammanfattning : In later years the development of pavement design has gone towards more and more analytically based methods. Future design will probably be based on incremental deterioration models. The objective is to evaluate different types of rut depth prediction models for an incremental design process. LÄS MER
