AESCO/Madsen EcoFoam-II Warm Mix Asphalt Injection System

The AESCO/Madsen static inline vortex mixer, known as the Eco-Foam II, is a motionless static mixer in which fluids are injected and rapidly mixed by a combination of alternate vortex shedding and shear-induced turbulence, which produces superior fluid mixing.

• Unmixed asphalt flows to the static mixer and is forced through the mixer restriction to form a high-speed flow
• Water/additive is injected into the low-speed reversed flow region downstream of the mixer tabs
• Water is injected and rapidly mixed with the hot liquid asphalt by a combination of alternate vortex shedding, and shear-induced turbulence
• Double swirl pattern guarantees injected water will be rapidly mixed downstream of the mixer resulting in a homogeneous “foamed asphalt” mix
• System includes variable speed high-pressure water pumping and metering system with stand alone computerized controls
• Can be easily retrofitted to any asphalt plant
