GMS Soil Stabilizer Case Studies

SS proved extremely effective, saving us about half on our road building costs...”

“It made even our most pessimistic people believers to see us haul all winter over two inches and less rock”

Tom Swarts, Logging Manager
Columbia Vista Corporation, Vancouver, Washington

Columbia Vista Corporation, a lumber company located in Vancouver, WA, applied Soil Stabilizer (SS) to stabilize their logging roads. Columbia Vista transported more than 250 logs over the treated roads in varied weather conditions. These logging roads were normally built with rock much larger than two-inch minus, which can cause extensive wear to logging trucks and tires.

The stabilization of the treated roads proved cost-effective in terms of road construction costs and truck maintenance.

This 1,000’ stretch of road, basically built to residential specifications, is being exposed to heavy axle loads from freight trucks, construction vehicles, tank trucks, and the type of traffic that normally goes in and out of freight and construction yards, along with traffic to and from the sewage plant, which has a facility for septic tank trucks. Inspection of the road shows no stress fatigues and there is no indication that this road does not adequately carry the axle loads it is being subjected to.”

Tor Lyshaug, Project Engineer Director
Multnomah County Oregon
Division of Operations and Maintenance

The Multnomah County, Oregon Division of Operations and Maintenance applied Soil Stabilizer (SS) to a 1000-foot stretch of road during the construction of the Inverness Sewage Treatment Plant.

The road was built to residential standards, according to Tor Lyshaug, then Director of the Division of Operations and Maintenance. The subgrade was covered with a 7” layer of 1 ½” – 0” gravel and a 1” layer of ¾” – 0” leveling course. The surface was a 2” class B asphalt pavement and the total section was 16’ wide.

The treated stretch of road was exposed to heavy axle loads from freight trucks, construction vehicles, tank trucks, and the related type of traffic normally associated with freight and construction yards.

Despite heavy exposure to such heavy axle load traffic, the road maintained its integrity without signs of stress fatigue, according to Lyshaug.

I feel that controlled use should not pose a significant acute hazard to fish or animals using water from streams flowing from your areas treated.”

The Forestry Sciences Laboratory performed testing to evaluate the acute toxicity of the product to rats and fish.

A bioassay of the acute toxicity of the product to guppies was conducted at 20° C. in pH 7.2 fresh water. Fish averaging 10 mm in length were contained in each of 10 jars containing diluted concentrations of the product.

It was determined that concentrations less than 300 ppm in water will probably not have an adverse impact on fish.

A second testing was performed, in which white Wistar rats from the Oregon State University Department of Agricultural Chemistry were exposed daily to 1,000 ppm of product in their drinking water. Animal weights and water consumption were determined during a 24-day test period.

Results yielded from the second testing indicated no major impact of the product on either survival or weight gain.
