Fiber Bragg technology to design new asphalt model
Pavement design is essentially and usually a structural long-term evaluation process which is needed to ensure that traffic loads are efficiently distributed at all levels of the total road structure. The total road structure consists of a top layer, one or more base layers, subbase and subgrade
The object of this project is the delivery and placement of Fiber Bragg Grating Sensors (FBG Sensors) in road pavements.
This concerns the delivery and placement of these FBG Sensors in both the foundation, the asphalt profiling layer, the asphalt underlayer and the asphalt top layer. The FBG sensors are placed in the warm asphalt during construction.
The delivery and placement of the FBG sensors is part of a study conducted by the Port Authority together with the University of Antwerp; “Sustainable asphalt pavements for heavily loaded road surfaces”. In order to get a correct model of the loads and the associated deformations in different asphalt types, but also in the foundations, different test sections will be laid within the port area.
These test sections will be equipped with these FBG sensors in order to be able to achieve an accurate follow-up of the deformations in the road structure. The results of the measurements are then processed by the University of Antwerp in the current study.
