Strains in composite reinforcement at the base of a road embankment
In this case study, the base of the road embankment was reinforced with composite rebars oriented in two directions. This approach enhances durability, given composites’ high resistance to corrosion. Some rebars were replaced with EpsilonRebars, serving a dual purpose within the structure as both sensors and reinforcements. The inclusion of two measurement layers further enabled the calculation of vertical displacement profiles.

Results of using the DFOS monitoring system
The measurement sessions took place during the construction process and the embankment operation. The figure below shows example strain profiles obtained from transverse EpsilonRebar during subsequent load steps (during construction of new embankment layers). Data interpretation was performed taking into account the initial topology of the substrate, as well as temperature distributions obtained thanks to Raman measurements. Vertical displacements at the base of this structure were calculated based on measured strains and known spacing between two measurement layers.
