Do you know Role of Pavement Strain Transducers in Pavement Engineering?

Aimil Ltd Podcast

Pavement strain transducers (PAST) are devices embedded in roads to measure strain on the pavement layers. This data helps engineers understand how well the road is performing and predict its lifespan. PAST validate theoretical calculations of stress and strain on pavements, and the data is used to optimize pavement design, evaluate maintenance effectiveness, and for research and development of new road materials.
