For this installment of “Where are they now?” we look back at LEAP Technologies (Low Energy Asphalt Pavement). LEAP was an innovative company using microwave technology to heat 100% reclaimed asphalt concrete, adding in some new, light oils, mixing it together, and sending the recycled hot mix out for paving. The microwave heating replaces the usual, natural gas-heated drum used in traditional asphalt plants.
The beauty of the microwave process is that it is emissions free; the plant is portable and can be set-up in a warehouse allowing for all-weather production. Good patching of utility repairs in the winter when asphalt concrete plants are closed, is possible.
There was a big public relations push for this technology in 2015. A spokesperson said… TO BE COMPLETED
LEAP Technologies is now LEAP Enterprises, a computer privacy company focused on technology and biology in Brooklyn, Minnesota.
