Hydronic Heated Pavement System Using Precast Concrete Pavement for Airport Applications

摘要

The use of deicing chemical has the potential to cause environmental and safety concerns and pavement deterioration. Hydronic heated pavement systems (HHPS) have been widely used to melt or prevent ice and snow accumulation on paved surfaces. HHPS uses heated fluid circulated through pipes embedded in the concrete pavement to warm the surface of the concrete. The objective of this study is to develop a conceptual design framework and construction guidance for large-scale HHPS using precast concrete pavement (PCP) technology to expedite construction work and minimize air travel disruption. The detailed design and 3-D visualization of construction procedures has been developed for HHPS using PCP technology. The outcome of this study will help contractors and transportation agencies to envision the constructability of different components in HHPS, including tubing patterns and construction procedures.
