Many transportation agencies, along with cities and municipalities, private business owners, etc. allocate a significant amount of time and resources each year to remove ice and snow from their paved surfaces to achieve a safe, accessible, and sustainable transportation network and pavement surface during winter weather events.
An electrically conductive concrete (ECON) heated pavement system (HPS) has been shown to be a promising alternative to the conventional snow removal operations using snowplows and deicing chemicals, which is time-consuming, labor-intensive, and environmentally unfriendly. ECON HPS utilizes the inherent electrical resistance of concrete to maintain the pavement surface above freezing and thus prevent snow and ice accumulation on the surface. The purpose of this study was to demonstrate the full-scale implementation of 10 ECON HPS slabs constructed at the south entrance of the Iowa Department of Transportation’s main campus in Ames, Iowa. This study consists of system design and control, field implementation, and sensor instrumentation procedures for the construction of the ECON system, which took place in October of 2018. A programmable logic controller (PLC) was designed, programmed, and utilized to control, operate, and monitor the system remotely. The heating performance of the ECON slabs was evaluated using the instrumented sensors under a number of snow and ice events in 2019 and 2020. The performance evaluation showed promising results in providing snow- and ice-free pavement surface through several harsh winter weather events.
