Midwest's SF2 Builds Stronger, More Durable Pads and Roads Constructed with Locally Available Soils and Advanced Chemisty
SF2 is a synthetic fiber and synthetic fluid road stabilization system that enhances compressive strength, CBR, shear strength and material adhesiveness.
It does this through advanced nanotechnology that binds native soil together at the molecular level. First, a layer of synthetic fibers is laid down on the road surface. Then, the SF2 synthetic fluid is layered on. The fluid is engineered to coat and load each soil particle which, together with the SF2 fibers, creates a matrix that can withstand extreme traffic loading. The fibers and fluid are then blended into the in situ soil or placed aggregate to a depth of six inches. This means that culverts or underground utilities won’t be disturbed.
After grading and compacting the blended mix of SF2 and soil to the designed density, a final topcoat of SF2 liquid is applied, which can be followed by a stone wear course. The road is then immediately ready for traffic.
This unique binding action allows the road to grow in compressive strength over time, with heavy traffic usage.
In addition, roads stabilized with SF2 are water-resistant and, unlike Portland cement, impervious to freeze-thaw cycles. All of this means less maintenance, fewer and easier repairs, lower lifecycle costs and fewer delays to the movement of your supplies, material and equipment.
“I was somewhat surprised in that the pad surface actually was more hardened after winter breakup this past year. That has to be due to the aging process of the synthetic fluid binder material.” – Mike Matteucci [Program Consultant] (18 months after application of SF2)
