Soil stabilizer is a safe, effective, non-corrosive liquid enzyme soil stabilizer

that significantly enhances the properties of the soil used in the

construction of road infrastructure.

The result is a better and longer lasting soil stabilized road with increased

CBR loading, reduced soil permeability and increased road strength. These

lower a road's construction and maintenance costs while increasing the

overall quality of its structure. This Technologies is easy to use and is not

harmful to the soil or its applicators.

• Standard Road Design

AASHTO Structural Number modeling is

supported by lab and field tests of stabilized

materials to verify strength comparisons

between design options. Using published

correlations, standard test measurements are

related to CBR values and structural

coefficients, allowing cost comparisons

between designs of similar strength.

• 지오마린 지반개량 공법(I) / GeoMarine soil improvement method(I)

Alternative #1 Maintains the standard

design strength while reducing or

eliminating costly materials through

stabilization of local materials or

economical material blends for typical cost

reductions of 20% - 30%. Laboratory

verification of soil blends can be

performed before project execution.



• 지오마린 지반개량 공법(II) / GeoMarine soil improvement method(II)

Alternative # 2 improves the standard design through stabilization of

available materials blended to optimize

gradation and plasticity. The result is a

maximum increase in stabilized strength.

Note that savings of 40% are possible by

thinking outside of the standard design

and road materials. Cost comparisons to

matching structural upgrades using

traditional materials and designs generally

favor stabilization.

The Benefits of using Soil stabilizer.

Governments need to invest their monies in building superior roads that

have:

a) reduced construction costs

b) longer useful lives

c) minimal road maintenance costs

d) better wear qualities

e) increased transport capacity

f) greater passenger comfort

g) lower vehicle operating costs

h) reduced traffic accidents

i) excellent environmental safety

For paved roads, stabilizing the base and/or sub-base layer with

GeoMarine.

1. Improves the soil structure sufficiently to achieve confirmed savings of

25% to 30% in paved road construction costs.

2. Strengthens the road structure of highways needing repaving and

eliminates the need to remove and dispose of old asphalt. Recycling

and stabilizing asphalt increases structure strength two to three times.

3. Strengthens base layers and sub-base layers in preparation for chip

and seal operations.

4. Increases the capacity of the road surface to support traffic loads.



5. Reduces such common road surface problems as cracking and surface

loosening.

6. Reduces the cost of purchasing and transporting construction materials

for road reconditioning by reusing in-situ materials and upgrading and

improving poorer quality local soils.

7. Extends the useful life of asphalt and concrete road surfaces and

stabilizes highway road shoulders. Construction savings of 10% to 25%

can be achieved from reduced aggregate and hauling needs.

∎ Uses In Road Design.Stabilization technology has advantages in a wide variety of road applications from roads that will remain unsurfaced to those that will receive surface treatments. Stabilization approaches include improving existing materials such as native soils, old graveled roads, degraded asphalt over contaminated base, etc. as well as maximizing potential road strength by blending in missing gradation or plastic components.

‣ Unsurfaced roadsLiquid enzyme soil stabilizers make it possible to use local soils “as is” to create roads that are intended to remain unsurfaced such as are commonly seen in rural, access, mining, logging, agricultural and village applications. Soils with existing gradation and plasticity can usually be improved, as can gravel roads or base materials contaminated with fines, and degraded asphalt roads that have reverted to “gravel.” Liquid enzyme soil stabilizers are also a powerful way to use blends of local soils and amendments. This works particularly well when: • Increasing gravel content to support increased traffic loads • Increasing plastic fines to lock up loose surface gravel • Supplementing gap- graded materials to increase strength and resistance to

water penetration • Creating a high-strength base layer by mixing RAP from degraded or milled

asphalt with a stabilized soil binder

‣ Roads that will receive a surface treatment Asphalt pavement life can be greatly extended by stabilizing base and sub-base layers, whether local soils are used “as is”, or blended with amendments to improve gradation and plasticity.

‣ Surface treatments on stabilized base materialsLiquid enzyme soil stabilizers add performance to roads that will receive a surface treatment of MgCl2 for total dust control. Stabilized bases can be given a surface seal of penetrating asphalt as a weatherproofing for highly plastic clays or a surface binder for granular mixes. Single and double chip surfaces, or asphalt pavement are commonly placed over a stabilized base or sub base structure.

‣ Incorporating RAPAdding soil stabilizers to RAP (recycled asphalt pavement) mixed with up to 50% of soil materials creates maximum road strength (based on IGES test results). The approach of recycling (RAP) + stabilizer + soil has proven to be highly efficient, as it combines four stabilization steps in one. Production rates in excess of 50,000 square meters per day are achievable. This method yields a significant increase in strength and material uniformity in a stabilized bed that is immediately ready for

shaping and compaction.
