Laboratory Testing of an Externally-Heated Bridge Deck Subjected to Wind
Hydronically-heated bridges are often used for bridge deicing with shallow geothermal energy extracted from underground loops as the energy source. Previously heated bridge designs are limited for implementation on new bridges since the heating loops are embedded within the concrete deck during bridge deck casting. This study describes the testing of an externally heated concrete slab under simulated environmental conditions. This heated slab consists of PEX pipes attached to the concrete deck bottom and encapsulated in geofoam for heat insulation. A fan was position at the top of the slab to create various wind speed over the test area. The temperature response at 1 inch below the slab surface was monitored under various wind speeds. The results show that there is a significant effect on the heating performance of the heated bridge deck due to the wind.
