Super-portable plant produces
Terex Roadbuilding has extended its line of super-portable counter-flow
asphalt plants with the introduction of the E225P. The unit has a production
capacity of up to 225 tons per hour and can be moved in five loads. The
counter-flow drum’s new flight arrangement offers more efficient aggregate
heating and asphalt mixing, according to the company. It is recommended for
a wide variety of mixes, including Superpave and stone matrix asphalt. The
base plant has the necessary electronic connections to accept recycled
asphalt, and Terex says its counter-flow technology enables the E225P to run
higher percentages of RAP than parallel flow designs.
