NordFoU - Pavement performance models. Part 2: Project level, unbound material

The NordFoU Pavement Performance Models project is a research project that is financed by the Nordic countries. This is an implementation project and the main objectives of this project are to: Implement recent research results to test methods and models that should be used of normal engineers in the road design work to predict future performance. The work consists of adapting existing performance prediction models, utilizing data from test and reference sections, improving the test methods and models and stimulates the development of expertise in the field of performance modelling (prediction of condition) for road structures. The project aims to deliver a practical tool for calculating the future performance of pavements, which is much more easy to use, and probably gives better predictions, than the US "Design Guide", In this work, some models for prediction of unbound materials have been evaluated in order to choose the most suitable models for unbound material in the Nordic roads.
