LC Sensor Applications in Civil Engineering monitoring of water within asphalt concrete pavement structures trapped water or moisture from precipitation, snowmelts, subsurface water tables and run-off strip the asphalt cement from the coarse aggregates, damaging the structural integrity of the pavement. weak spots (water concentration zones) in the concrete components of bridge structures, thus preventing issues such as freeze thaw (i.e., expansion and contraction of civil structures due to weather effect on ice lenses). to determine water penetration in hydraulic structures such as dams and flood restraining embankments.
