Design of pavement structures has a great impact on life cycle cost (LCC) and environmental effect of pavements. At present pavement structures in Norway are designed with use of empirical based tables and requirements described in the Norwegian design guideline for pavement structures. The current design procedure does not allow prediction of performance and evaluation of the effect of changes in material, climate, and traffic, which makes it difficult to accurately calculate the LCC and environmental impact. Mechanistic-empirical (ME) systems can overcome these shortcomings since they allow prediction of performance based on realistic material, climate, and traffic data. Therefore, a research and development program was initiated by the Norwegian Public Roads Administration (NPRA) to further develop and implement a ME design and analysis system for Norwegian conditions. The work involved evaluation of existing ME systems around the world to find a system that can be adapted to Norwegian conditions. Based on this evaluation a system called ERAPave PP (Elastic Response Analysis of Pavements –Performance Predictions) which was under development by The Swedish National Road and Transport Research Institute (VTI) in collaboration with the Swedish Transport Administration (STA) was selected. NPRA and STA established a cooperation program to further develop and implement the ERAPave PP in Norway and Sweden. The objectives of the project were to further develop ERAPave PP by adding models for climate and frost heave, as well as to establish databases for implementation of the system in each country. This paper describes the process with selection, further development, calibration, and implementation of ERAPave PP for Norwegian conditions.
