Building stronger and more sustainable roads

ROAD//STABILIZR® is a long-term soil stabilization solution for roads that require continual maintenance due to wet weather and marginal road materials. ROAD//STABILIZR® targets soils with high clay content by increasing density and providing enhanced stability and strength.

ROAD//STABILIZR® is biodegradable, non-toxic, non-corrosive and is specifically engineered to work on high clay content soils, which would normally be considered marginal in terms of their engineering properties. The product allows for the use of these types of in-situ materials providing substantial cost savings over traditional materials for road building, such as aggregate.

The roads built with ROAD//STABILIZR® are stronger, more dense and stable – proven to be effective in both wet and dry conditions and during freeze-thaw cycles.

Why choose ROAD//STABILIZR®?

Unique catalytic product, developed to aid the workability, mixability, binding and compaction of clay-based materials

All-natural environmentally-friendly product

Reduces swell and permeability

Increases CBR (California Bearing Ratio) value - a measure of road strength

Cost-effective soil stabilization method for improving material strength and durability

Easy application through standard road building equipment

Induces cationic action, which binds dust particles together to help reduce road dust emissions

Long-term savings over product life cycle, through reduced maintenance and increased efficiency

This is a far superior way of building roads. It reduces maintenance costs dramatically, it reduces input costs, almost entirely eliminates any environmental impacts.

FAQs

How soon after construction can the road be opened to traffic?

The road can be opened as soon as final compaction is complete. In fact, the road will benefit from the compaction of traffic, further increasing its strength. The more traffic on the ROAD//STABILIZR® soil stabilization treated road, the better, as it helps to sustain the high densities and compaction values achieved during the construction process.

How much gain in CBR can be expected?

CBR gains will vary depending on the material being treated, and the densities achieved during construction. Increases of 50% to over 300% have been realized on various projects and during lab testing.

Can the surface be maintained, should it be damaged or worn?

Yes, maintenance can be accomplished when necessary. It is typical to complete a light grader trim from time to time, on an as needed basis. ROAD//STABILIZR® treated roads require significantly less frequent and lighter maintenance than untreated roads.

How should we profile the road?

Road profile is key in the performance of an unpaved road. Ideally, dual lane unpaved roads should be graded to between 3-5% to a central crown. Drainage and profile errors result in water pooling and erosion that will undermine the road.

Does water quality affect the result?

No, water quality does not affect the performance of ROAD//STABILIZR®. Fresh, reclaimed, brackish and seawater have all been used successfully for soil stabilization with ROAD//STABILIZR®.

What are the main elements of ROAD//STABILIZR®?

ROAD//STABILIZR® consists of organic catalysts, electrolytes and surfactants. These three main elements work together to penetrate clay-based soils and alter the clay particles to become strongly and semi-permanently bonded to each other. Once altered, the clay particles behave like a flexible cementing agent that locks aggregate material in place. ROAD//STABILIZR® acts as a catalyst to remove excess water and promote a high degree of compaction and densification.

If we double the application rate, will we get twice the strength?

No, the effect of ROAD//STABILIZR® is not linear and increasing the application rate will actually reduce the beneficial properties by reversing the bonding of the clay particles. ROAD//STABILIZR® is engineered in combination with the application rate to achieve optimum performance.

Will ROAD//STABILIZR® be affected by freezing or thawing?

No, ROAD//STABILIZR® itself is freeze-thaw stable, and ROAD//STABILIZR® treated roads are less susceptible to swell and damage caused by freeze-thaw cycles. However, ROAD//STABILIZR® should not be applied in freezing conditions.

We are still getting the dust from the road 3 weeks after application, why?

ROAD//STABILIZR® is primarily a soil stabilizer that provides some dust control due to the increased compaction/binding of the soil, but dust control is not the main target. If the treated material is lower in clay content and higher in silt fines, some dust is expected as ROAD//STABILIZR® only works on the clay particles within a soil/gravel mix. If dust control is required, DUST/BLOKR® should be considered as a supplementary surface treatment to a ROAD//STABILIZR® application.

How important is it to have some larger aggregates in the soil?

It is important to have some larger aggregates in the soil to allow for strong binding sites for the treated clay fraction. The soil does not require large aggregates but should have some gravel. If there already is gravel or stone in the scarified soil, do not remove it as it creates a good bond with the stabilized soil. If the inclination is high, add 5 cm of gravel in scarified soil, grader it and profile the road. After this, scarify it again and then apply ROAD//STABILIZR®. Homogenize the mixture with the grader (full length and return). When optimum moisture is achieved proceed with compaction. After the first pass with the compactor, add another 2-5 cm of gravel on the newly compacted surface which is still penetrable to create a very good anti-slippery surface. Use this procedure for high inclinations. The created bond between ROAD//STABILIZR® soil and gravel becomes very strong.

There is a lot of sediment in the bottom of the drum, why?

ROAD//STABILIZR® is distributed in a highly concentrated form; 1 L of ROAD//STABILIZR® treats 33 m3 of compacted soil. It should be lightly agitated prior to use. Even if some sediment is present performance will not be impacted and will be fully effective.

Is drainage necessary?

A well-drained road profile is necessary for all road construction projects, as well as means to freely transport run-off away from roads such as ditches, table drains and culverts. Water is called the “universal solvent” as it can dissolve and erode any material; managing it is paramount to success.

How important is compaction?

Compaction is second only to moisture content in the successful construction of a ROAD//STABILIZR® project. Consistent with standard construction best practices, a sheep’s foot or padfoot roller, steel drum and rubber tire are all used at different phases of the project. While all rollers have their place in the construction process, ideally a rubber-tire roller should be used for final compaction; however excellent roads have been built using a steel drum roller and the water truck as the finishing roller. Heavy traffic immediately after construction will accelerate the curing process, help maintain compaction levels and help seal the surface.

Will rain during construction affect the project?

Yes, moisture content is extremely important to the success of a ROAD//STABILIZR® project and rain should be avoided during construction. Best results are achieved when the soil is compacted at Optimum Moisture Content (OMC), and rain will typically raise the moisture content above OMC. Issues that can arise from construction at moisture contents above optimal include lower compaction, surface cracking and delamination.
