Western Stabilization Recycling - Mixing the recycled road material with the foam bitumen (asphalt)

The WR2500S used in soil stabilization could have an 8 ft or 10 ft mixing drum. When combined with a foam asphalt spray bar the Wirtgen WR2500S has the capability of recycling the existing road material to provide a new and stronger road base.

This video show the mixing processes. The hot bitumen, air and water will be mixed together at precise amounts to produce the foamed bitumen or sometime called foamed asphalt. The resulting foamed bitumen is then introduced into the mixing chamber, to be mixed with recycled road material. The video shows the pulverizing of old road base for recycling and the mixing of the foamed asphalt process in one step. Sometimes it necessary to pre-pulverize and introduce a stabilizing agent before the mixing can be accomplished.

Please see our video "Foaming" for a more complete look at how the foamed asphalt is produced.
