Stansteel’s Accu-Shear

The Accu-Shear® from Stansteel/Hotmix Parts, Louisville, Ky., is designed for advanced in-line water foaming of liquid asphalt cement (AC). The shearing process promotes total blending and homogenized flow for warm-mix asphalt (WMA) production. The Accu-Shear is also engineered for in-line blending of rejuvenators, latex, emulsions and most liquid chemicals on the market today with the optional four-port additive manifold. Here’s how it works.

First, a technician installs the Accu-Shear in the asphalt injection line prior to the mixing zone. From the control center, the operator selects a mix design that will activate and control each additive as required. The plant’s automation controls the production rate and flow rates of each liquid additive.

By using the 15-horsepower variable speed motor to force the material together, AC and water are blended mechanically, not injected. According to the manufacturer, this positive blending of the additives with the liquid AC increases the foaming action and maximizes coverage of the heated aggregate.
