The Minneapolis airport has a machine similar to the one shown above. It's only a few years old and only two guys out of probably 120 maintenance guys are trained to run it. The one at MSP is built on a Freightliner chassis (if I'm not mistaken) and was rumored to cost over 1 million dollars. It does the removal with super high pressure water and captures all the removed rubber into a hopper at the back of the truck where it can be dumped into a recycling container at the shop. In Minneapolis, rubber removal is only performed during the spring, summer, and fall months..... in the winter months the rubber is controlled by the snow plowing and brooming process. Mainly the brooming process...... with either a dedicated Oshkosh runway broom, or an Oshkosh MFE which has a runway plow, AND a runway broom on the same machine.
