IPPL SS-IX


POLYMER ROAD STABILIZER

IPPL SS-IX Polymer is a third generation road stabilizing polymer and a dust suppressant. It is the flagship product of IPPL to be used extensively for stabilizing the base and sub-base layers of roads, Mine Haul Roads, Parking Lots, Hard Stands and Container Depots.

The product has been widely used since inception, in the sectors covering Defence, NHAI, SH, Ware House management, Container Handling segments etc in the country with good performance and durability. The product gains excellent strength from mechanical compaction and is an excellent solution for heavily trafficked roads and hard stands.

Bonding: IPPL SS-IX Polymer mixed with water is sprayed into the soil to be stabilized using standard water browser. On compaction the polymer molecules bind together with the soil increasingly with running traffic, the polymer atoms bind tighter and tighter as water molecules evaporate and the road becomes tough and stronger. Lab tests: Have consistently shown increased structural strengths over a period of time. Due to the flexible nature of the polymers, the pavement surface allows a certain amount of flexibility on the road and does not become brittle. The maintenance on IPPL SS-IX stabilized roads are dramatically reduced in comparison to traditional other stabilized roads.

Structural Guarantee: All IPPL SS-IX applications are guaranteed to exceed the AASHTO structural load bearing axle capacity. Road base/sub-base will be tested for its binding capacity and if necessary, will be modified to meet the standards as per road design.

Construction Speed: Stabilize up to one kilometer per day using traditional equipments, see pictures. Alternatively one can use soil stabilizing/pulverzing machines to stabilize up to three kilometers per day.


POLYMER SOLUTIONS

1. Asphalt Roads: Ideal for stabilizing base & sub-base layers. In most instances, the in-situ soils in the area can be used for stabilization. The stabilized road is opened to heavy traffic within 72 hours after construction, as the additional traffic on the stabilized road actually assists in dissipating the water in the base and sub-base, thereby speeding up the polymer binding process and the structural strength of the road. After checking the moisture content, prime coat applications followed by bituminous wearing course is undertaken.

2. Rural Roads: IPPL SS-IX is ideal for providing a tough base layer. Cost effective aggregate seals can be applied as a wearing course. In some instances, due to economic reasons, the rural roads may be left unsealed- with no wearing course. In this instant, a light clear polymer binder can be sprayed over the existing stabilized road as a cost effective interim measure. It may be necessary to apply a diluted polymer spray over the stabilized area every 6 months pre monsoon.

3. Mine Haul Roads: IPPL SS-IX can be used over the specific crust designs for unsealed polymer stabilized layered roads that will provide the structural load bearing capacity of these heavy haul vehicles.

4. Railway Embankment: IPPL SS-IX can stabilize Railway Embankment / base to its best requirement of load bearing capacity of the tracks.

5. Shipping Yards, Container Depots, Helipads, Airstrips & Parking Lots: IPPL SS-IX with its flexible base and sub-base layers provides excellent strength for stated applications, which thereafter can be paved as per requirement.


IPPL SS-IX POLYMER OVERVIEW

Many years of lab and field development have resulted in IPPL SS-IX using a combination of nanotech polymer
molecules, mainly consisting of two sizes- 5μm and 0.1μm.

The 5μm polymers bind the aggregate in the base-layer while the 0.1 μm nano-polymers migrate deeper into the
sub-base layer, thereby stabilizing another layer, although only one layer may have been stabilized. This dual
nano-technology is unique to IPPL SS-IX.


TEST REPORTS PRIOR TO DESIGN PROCESS

To guarantee that we will exceed AASHTO structural load bearing axle capacities, it is important to consider various
pertinent factors before applying IPPL SS-IX stabilization polymers, adequate representative soil samples should be
taken and tested for:

  • Geo-Technical Report (Gradation, F.S.I., L.L., P.I., MDD, O.M.C, Gradation & C.B.R.) of the carriageway to be stabilized.
  • In case of formation; F.S.I., P.I, and C.B.R. of the soil to be used for the subgrade.


DESIGN PROCESS

  • A pavement design is formulated based on the following:
  • Type and nature of traffic use of the pavement
  • Percentage of heavy vehicles and axle loads
  • Life span of road
  • Current traffic use
  • Cumulative increase in traffic load over life of road
  • Environmental conditions
  • Type of material to be stabilized and its testing
  • Testing for strength capability (Unconfined Compressive Strength / Resilient Modulus) of the Soil after
    addition of IPPL SS-IX
  • Based on the above results-Stress- Strain Analysis of the designed pavement for its Crust Reduction
  • The Dosage of IPPL SS-IX varies based on the above criteria. However, optimal polymer dose @ 0.5%
    of the stabilizing
    material by weight is treated / consumed, in all probability.
  • OPC grade 43 may be applied @ 1-2% by weight of the stabilizing material on specific cases only

SOIL TESTING PRIOR TO CONSTRUCTION

1. Establish plasticity Index of the Original ground / Material to be stabilized. Incase PI is more than 10%,
    modify the material by adding Non Plastic Material.
2. Establish C.B.R. of soil.
3. Establish Maximum Dry Density and O.M.C. of soil- to ensure optimum compaction.
