Firmaroad (M.O.E.)® SS-3 SOIL STABILISER
How to use Firmaroad SS-3 on site
Firmaroad SS-3 targets only the clay fraction of the material it comes into contact with and once treated the clay particles no longer attract water and transform into useful fines which are essential binders in pavement aggregates.
Clay particles, once treated are transformed permanently and actually assist in strengthening pavements and other earthworks structures.
The clay no longer acts as problematic material which causes extensive damage, leading to expensive repairs in pavements.
Firmaroad SS-3 transforms undesired/rejected clay bearing material into useful pavement product reducing the need to import costly quarry products.

FIRMAROAD SS-3 soil stabiliser
Anticipated subgrade & base material strength increase after Firmaroad stabiliser is applied.
- Stronger Bond
- Increase density
- Increase mechanical strength
- Increased resistance to water penetration
- Reduced dust loss
- Allows the use of more institute material
- Allows the use of more institute material
- All the above means less costs for extended pavement life.

Firmaroad SS-3 Soil Stablizer
FIRMAROAD SS-3 soil stabilising chemical is suitable for-
- Road pavements, both sub-grade and base-course
- Air strips and Helicopter pads
- Dam walls, settlement ponds etc.
- Construction machinery storage / display areas
- Logging truck roads to increase accessibility and reduce delays
- Pot hole repairs in damaged roads
- Parking lots
-
Large animal feed lots – more animal friendly and less expensive than cement
- Existing in-situ material containing Clay (Ground Surface Preparation) at Pre-Construction Stage.

Step 1
Rip the existing road formation to the required design depth –
generally 200 -250mm minimum.
The area to be worked will need to be ripped by a grader to loosen the material for mixing. The stabilising chemical must be evenly mixed through the loosened road base so it comes into contact and treats as much of the material as possible while reaching the optimum moisture content for compaction.
Step 2
If required, add material to existing work area as determined by site engineer or FIRMAROAD Technical Advisor and level with grader. If the surface is lower than the desired design, add material which has been tested and confirmed suitable to achieve the required CBR results. The site engineer/supervisor can check the user instructions for a guide on suitable materials which should contain the recommended amount of fines/clay particles which will react to the chemical for a tightly bound hard pavement.
Step 3
Simply add FIRMAROAD chemical to your water truck and follow the process below.
“IT IS THAT EASY” Add FIRMAROAD stabilising chemical to the water truck/bowser. Refer to the user guide for quantity to be added. The standard quantity is 200ml of stabiliser to 1 cubic mt of material to be treated. The chemical will quickly disperse in the water bowser without the need of any additional action by the site workers. The water bowser can proceed to work immediately.
Step 4
Add mixture of FIRMAROAD and water using a stabiliser machine or water truck to bring the moisture content to optimum levels. (Use unsalted water only.)
If mixing with a grader, empty the entire water truck evenly over the ripped area. You may need to do this more than once, depending on the area to be mixed. Note: If the area to be mixed is close to OMC, it will need to be dried enough to allow the FIRMAROAD /water mixture to be added allowing the required dosage of chemical to be included reach the OMC.
Step 5
Mix the materials using a grader or pavement stabiliser machine to achieve optimum moisture. Begin mixing with the grader until reaching the recommended moisture content. (It is advised to mix the material until just over the required OMC, so it can dry back slightly) Alternatively, the water-chemical solution can be mixed in by stabiliser machine. The chemical does not damage the stabiliser machine. Simply wash/flush out the machine at the end of shift.
Step 6
Once evenly mixed shape the road formation in accordance with the relevant project design requirements while using a vibrating sheep-foot/padfoot roller for compaction. Using a roller of around 16 -19 ton and giving 5 passes in each direction should get the desired results with a mix 200mm/250mm deep. After compacting remove this roller, spray water lightly over the mix before reshaping with grader. Use flat drum roller with heavy vibration to give two passes over the road. Finish the surface using flat drum roller on light vibration and multi tyre roller behind the grader.
Step
Complete the road surface preparation using a vibrating smooth drum roller and a rubber tyre roller behind a grader to obtain a tightly bound water resistant surface. Do not allow the surface to become dry while the grader is working. (Note: Usually only two passes are required with the flat drum on low vibration to get a hard smooth surface. Any further use of the flat drum should be without vibration). Continued use of multi-tyre roller and light sprays of water will assist in creating a tightly bound surface.
Step 8
The newly completed road is now ready for testing. In-situ field testing on site as work progresses can reduce the need to wait for laboratory test results. The surface can now be opened to traffic if needed, otherwise leave it to cure and harden more. Spray lightly with plain water to prevent fast drying. The CBR will continue to increase for up to four weeks to provide a durable pavement which can be either sealed or used un-sealed as desired.
Step 9
Apply Asphalt or Chip Seals according to Project specification or surface can remain unsealed to provide a long lasting all weather pavement. If sealing, allow the pavement to dry back and prepare the surface as usual.
Advantages of Firmaroad SS-3
It is an environmentally safe, non-toxic product which is easy to use by work crews.
Greatly reduces dust during the construction process in both rural and urban areas compared to cement stabilisation.
Increases road subgrade and base course strengths which allows reduced pavement thickness.
Less material = Less cost.
Significantly reduces mobilization costs as it is very easy and economical to transport, one 200lt drum will treat 1000 m3 of material. (Eg. a road pavement 5 m. W x .2 m. D x 1000 mt. L).
Treated material can be stored for days and will remain workable until compacted, which is very helpful for pothole repairing in both urban remote rural areas.
