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.

A new portable device to measure the frictional properties of bound and unbound materials for asphalt pavements.
IV creates a virtual world in which to model projects accurately in 3D, then render videos and images as well as immersive visualizations to create interactive simulation products. IV models are built from existing and proposed data, including agency design files (i.e., a Microstation roadway surface), while a game engine powers real-time presentation. When optimized with adjacent infrastructure to produce performance simulation, touch screen kiosks and virtual reality (VR) applications can provide a virtual helicopter tour over a proposed project, for instance.
Project NEON, Nevada's largest and most expensive public works project ever, was the catalyst for the initiative. IV helped convey complex planning and design scenarios to the public while helping project development personnel identify and resolve design and construction challenges, such as site impacts and right of way, geometric, and line-of-sight issues. IV products allowed the traveling public, homeowners, and businesses to see the potential impact of the project on their interests, while addressing their concerns and those of regulatory agencies about safety and environmental impact. As a result, IV vastly enhanced interagency coordination, regulatory review, and approval.
IV supplies much more freedom of camera movement than typical state-of-the-practice project visualizations, which provide views from specific angles. That enables non-outreach products like technical clarity visuals, graphics for related legal cases, landscaping details, and more. While conventional visualizations render various images for delivery via video files from which models are constructed for a given purpose, rapid, real time rendering through IV’s game engine technology eliminates the need to remodel, bringing its overall cost in line with traditional 3D visualization.
