Modelling and advanced design of perpetual road pavements
Overview
Background & policy context:
The entire Italian road national network, is nowadays highly degraded. There is the urgent need of new design techniques that could be able to implement solutions for producing road pavement of at least 50 years lasting life.
Nowadays it is impossible to achieve these targets with the current level of technology available on the market.
Objectives:
The research project aimed to achieve objectives of a key relevance both for Italian and international policy makers and researchers.
In the national context, the main objective was to make the concept of perpetual road pavements usable in real practice. Within the project, the definition of road eternal pavements is enlarged to include the possibility to insert support systems in the pavements.
Methodology:
The research was divided in different phases assigned to the involved Research Units:
- Real size load simulators
- Structural networks contribution
- Interaction between reinforcement and asphalt layers
- Development of an expert decision support system for the implementation of perpetual pavements in ordinary road
