ABSTRACT
The present paper aims to investigate the contribution of the Fiber Optic Sensors (FOS) system towards the assessment of the bearing capacity of asphalt pavements that have been Cold In-depth Recycled (CIR) utilizing foamed asphalt as a stabilization treatment for base works. The investigation is related with the need of understanding the behavior of asphalt CIR pavements under heavy traffic loads that can result in the prediction of pavement performance. On this purpose, a testing experiment was conducted to monitor and document the in-situ developed strains due to real traffic loading. The developed strains were measured using a FOS system. The collected data were processed and analyzed taking into account the local conditions.
