Electrically Conductive Concrete (ECON) Heated Pavement System (HPS)

Electrically Conductive Concrete (ECON) Heated Pavement System (HPS)


What is ECON HPS?


ECON HPS provides a new method of maintaining pavement surfaces above freezing, preventing snow and ice accumulation.

  ​

In 2019, the United States air transportation sector lost an estimated $33 billion of revenue due to flight delays. In 2020, 22.8 million metric tons of de-icing chemicals were consumed for roadway de-icing. These staggeringly high figures show that transportation agencies must continually work to make their networks more sustainable, efficient and resilient. ECON HPS helps achieve these goals by providing a new method of maintaining pavement surfaces above freezing, preventing snow and ice accumulation. The technology employs a heating element called an "ECON layer", electrodes, temperature sensors, electrical wiring, polyvinyl chloride (PVC) conduits, a control system and a power supply. The technology can be constructed either as an overlay on top of an existing pavement systems or as a top layer of a two-lift paving for new construction.

Benefits of ECON HPS are many. The innovation helps reduce the environmental impact and corrosive effects of de-icing chemicals. ECON HPS also reduces the time-consuming and labor-intensive methods for traditional de-icing, such as plowing and applying chemicals. Importantly, the technology fully complies with the Americans with Disabilities Act (ADA) guidelines.

To date, two draft technical specifications have been developed, and two patents have been filed. Numerous technical reports and peer-reviewed journal articles and presentations have been published.

ECON HPS has a wide array of potential applications, including at airports, among businesses and municipalities managing areas with high foot traffic; and by agencies responsible for roadway infrastructure, such as bridges, tunnels, ramps, high-volume traffic locations, and rest areas.
