Visit our Calculators page for APS road construction, APS dust and erosion control, and CAP cold mix asphalt. Enter the dimensions of your project for an accurate estimate of soil stabilization, dust control, erosion control, and cold-mix asphalt.

Basic soil stabilized road design requirement: 35% fines passing through a 200 sieve and 65% granular material where no stone is larger than 20% of the layer depth being stabilized. Best material: Dry Sand (or clay soil with less than 20% PI) and 5 to 10mm gravel.

For cold asphalt, you want to be at an average of 10mm with fine dust not going over 10%. If not, it will consume too much product.

For APS, once the performance has reached the limits of its longevity, a follow-up application is necessary to restore and rejuvenate its optimal performance. Reapplying APS to a previously treated area requires usually only 20% of the original application amount to achieve the same results.

For CAP, it behaves the same way as traditional asphalt when it comes to maintenance and repairs.

K31-APS does not dissipate (wash away) with rain. Heavier concentrations, will actually waterproof the treated surface.

Decreasing the application rate (increased coverage) will result in reduced strength, longevity, and performance for both APS and CAP. 

Yes, you can and here’s the protocol.

• Sands/sub-soils/ clay/ crushed mining, construction and other waste materials (not saturated materials).
• No particles larger than 5mm.  (angular not round)
• Preferably a minimum of 35%+ of fines passing through a 200 sieve.
• Any water can be used including seawater and mildly contaminated water.
• Calculate by weight the residual moisture and the optimum moisture of the material to be compacted. This will indicate the quantity of APS/water required to bring the mixture to OMC (Optimum Moisture Content).
• Use a mixture of 1 part APS mixed with 3 or 4 parts water.
• Compact the brick/block/paver and remove from the machine.
• Do not stack the bricks on top of each other to dry or they will stick together.
• K31-APS increases the CBR by a factor of 4-6 times.

  K31-APS and K31-CAP are water-soluble. Application equipment should simply be rinsed out after use. Cured K31-APS and K31-CAP need to be soaked with a degreasing agent and high pressure washed.

A hydroseeder is recommended to mix and apply seed, mulch, and K31-APS together. Our K31-APS will work as a super strength tackifier. It will also expedite the germination process of seed.

For APS, typically the polymer enhanced soil will withstand weights over 500 to over 1,800 psi. It depends on the soil. So yes it’ll be able to stabilize the soil and will not break down even with Heavy Haul truck traffic.

For CAP, keep in mind that any asphalt is only as strong as the base, if you have a weak base then it will fail. This is why we highly recommend using APS for the base and CAP for the asphalt surface giving you the ultimate road.

K31-APS is generally applied out of a water truck or hydro-seeder and needs to be applied by a contractor as the solution will alter the soil fabric to a slight degree. K31-APS is not much more viscous than water so when added to water it’ll self mix with no agitator necessary.

CAP can simply be mixed in a regular concrete mixer and stored in bags or stockpiles. The shelf life is over 3 years once it is mixed with the aggregate.

Yes, K31-APS actually replaces the traditional methods of having to import heavy stones and sand to build the road base.

The shelf life of K31-CAP is over 3 years once it is mixed with the aggregate. The shelf life of k31-APS is 3 years if kept away from the sun, but better to use it within the two years.

K31-APS works with most soil types, but we need plasticity to be 20% or less for top performance. It will still work on high PI soils but the finished product will not look or perform as good.

Some of our competitors mix the dust control agent with paints which can be high in VOC’s. When VOCs begin to break down, they will enter the environment and actually be more harmful than the native dust they were intended to stop. Our company holds itself to the highest of standards and prides itself on providing paint-free, environment-friendly products. APS is an eco-friendly product.

Yes, it can. One of K31-APS many purposes is to replace the traditional method of having to bring large stones, sand and/or laterite to build the base for roads or highways. In many ways, it’s a more practical approach because the strength is much more consistent than with traditional methods. Plus it saves tons of time, machine, labor and money in the base construction.

We receive an average of 35 inquiries daily and most ask for samples. As a business, this is totally unpractical. Therefore, it is our company policy not to send samples to anyone. Normally we sell by the container load, but we will make an exception on your first order to sell you a minimum of one tote of 1000 liters or either product.

The soil test is really quite simple.
Dig 10-15 cm in several areas of the project site and collect about 10 kg of soil. For example, if it’s a road then dig every 200-300 meters or so, or every time you see the color of the soil change. Then label your samples so you know which area they came from and take them to any lab. Have them test each sample for sieve analysis, proctor, MDD, OMC & plasticity index. Send us the results along with some photos and videos of the site and we will advise you on the best way forward. By the way, these lab tests should be done whether you are using APS, or any other type of product, or no product at all. If you want a solid road or road base you must always test your soil!
