A new scientific article is published in the MDPI Journal of Optical Sensors written by RTU scientists from the Institute of Telecommunications – Janis Braunfelds, Ugis Senkans, Jurgis Porins, Sandis Spolitis, Vjaceslavs Bobrovs; from the Department of Roads and Bridges – Peteris Skels, and Institute of Materials and Structures – Rims Janeliukstis.
Signals from optical sensors, buried under 25 mm of road material, indicate the temperature, strain, and number of cars passing the road. Different sizes of cars generate different strengths of strain and in this way, it is possible to distinguish between cars having 2 axles or even trucks with 6 axles. This study shows how Fiber-Bragg-Grating sensors can assist road engineers in analyzing the impact of strain and predict future designs to better withstand the strain in the long term.
