Rapid Deployment Dust Control


Depending on the natural environments military operations are set in, the presence of water – either too much or not enough creates – critical issues for aircraft, built infrastructure, logistics and equipment management.

Dust created during helicopter landing and take-off creates a period of vulnerability during which pilots and soldiers can easily become disorientated, especially while under attack.

With little to no ground preparation required, GRT: 3000 can be applied to open surfaces, immediately stopping dust generation for months at a time. Treated areas can be used within minutes of the product’s application, in some cases, immediately. This can help prevent the leading cause of helicopter crashes and the associated high cost to lives and capital.

In arid environments, unsealed, earthen runways generate dust and are also susceptible to deterioration from windstorms. GRT: 3000 can be used to quickly treat runways, using standard military (or civil) construction water trucks, controlling in-situ dust for months.


Logistics Yards & Vehicle Depots:

Dust is a huge source of equipment and vehicle damage. It accelerates the wearing of any moving parts and is in itself a significant respiratory health hazard for personnel.

Heavy trucks, forklifts, and tracked machinery (whether tanks or earthmoving machinery) damage all surfaces and generate dust, which also impairs visibility.

Only one treatment can handle this punishment – GRT: 3000.

This technology substantially reduces the need to remove in-situ material and import specialised pavements, or investing in high cost treatments such as concrete. GRT: 3000 is adaptable to many soil types, and works by soaking into the treated soil and simply weighs down particles, preventing them from becoming airborne.

Completely non-toxic and non-hazardous, GRT: 3000 treated materials need no rehabilitation or removal. They can be simply left in-situ and the ultimately biodegradable product will be broken down and absorbed into the soil.


Quality Assured:

GRT: 3000 is manufactured to ISO9001 standards and has been comprehensively reviewed by leading independent testing institutions and major companies worldwide.

GRT: Polymer Cement Modifier

GRT:

Polymer Cement Modifier (PCM)


Cracking of cemented gravels used in road construction have historical limited there use to specific applications; whereas if the cracking can be reduced or eliminated, their use could be extended to a much wider range of applications.


Hardened conventional cement paste has mainly an agglomerated structure of calcium silicate hydrates and calcium hydroxide bound together by the weak intermolecular forces. Consequently, microcracks occur easily in the cured material under stress. That is why ordinary cement mortar and concrete have poor tensile strength and fracture toughness. On the other side, in the polymer modified cement, it appears that the microcracks are bridged by the polymer films which prevent crack propagation, and simultaneously, a strong cement hydrate-aggregate bond is developed.

PCM also has a sealing effect to the formed structure and thus provide a considerable increase in toughness, waterproofing characteristics, resistance to chemical penetration, and freeze-thaw durability. Depending on traffic volumes, gravel characteristics and environmental conditions at the time, GRT’s PCM blend pavements can generally be trafficked immediately after final compaction; and once cured, provides a durable temporary running surface for construction traffic without the risk of suffering from degree of saturation failures that occur with unbound gravels. On larger projects, we can also formulate our additive to meet project specific requirements with regard to setting times.


A simplified description of the process for the creation of polymer modified cement is outlined below: After mixing with water, the cement paste particles start to hydrate and cement gel gradually forms on the surface of the cement particles. The unhydrated cement particles covered with cement gel is being enveloped with a closely packed layer of introduced polymer particles. The water removes by cement hydration and evaporation, and the closely packed polymer particles, positioned on the cement hydrates, integrate into continuous membranes. The membranes bind the cement hydrates together to form a monolithic network with the polymer providing increased flexibility and providing an improved barrier against uncontrolled drying of cement particles.

The binder should be added in sufficient quantity to balance both strength and shrinkage requirements to produce a bound material with significant toughness and fatigue strength to carry the design traffic loading. In most cases, cementitious contents for GRT polymer mix designs are limited to 2 to 3%. Even at these low dosages, we have found 28 day UCS results for some gravels to be in excess of 5MPa. Our testing has also found that depending on the gravel characteristics, the results achieved by GRT PCM with cement exceeds that sum of individual UCS test results of the cement and polymer alone thereby indicating that cross-linking of the cementitious binder and polymer has occurred. Our testing have also found that the PCM acts in a similar way to a water reducing agent in structural concrete.


GRT PCM Advantages:

Advantages of GRT polymer modified cement when compared to conventional cement stabilised or treated pavements include:

  • Significantly reduced or eliminated shrinkage cracking
  • Rapid curing at ambient temperatures
  • Higher tensile, flexural, and compressive strengths for the same cement content
  • Improved vibration dampening
  • Improved adhesion to most surfacings
  • Improved long-term durability with respect to freeze and thaw cycles
  • Lower permeability to water and aggressive solutions
  • Improved chemical resistance

Improved workability i.e. requires less compactive effort for a given depth of compaction and can be compacted in greater single lifts


Applications:

Due to its advanced properties GRT polymer modified cement has numerous potential applications:

  • Rehabilitation and strengthening of existing granular pavements;
  • Recycling of existing cement stabilized pavements which are exhibiting extensive shrinkage cracking;
  • Construction of pavements and/or working platforms in limited or constrained construction times;
  • In areas susceptible to high rainfall or inundation;
  • Over soft ground conditions where stiff bridging layers are required to compact overlying materials;
  • Where temporary trafficking of the pavement may be required during different stages of construction;
  • When preferred maximising of use of local materials and for making marginal pavement gravels suitable for purpose;
  • Modification or improvement of non-organic subgrade conditions;
  • Where construction water availability is limited as GRT polymer modified cement reduces construction water requirements and depending on the water quality may enable the use of non-potable water.

Polymer Soil Stabilization


GRT’s most advanced polymer soil stabilization product, GRT9000 was developed, for use in the construction of high-quality and cost-effective pavement applications.


Overview:

Inadequate pavements (due pavement life or increased traffic volumes) can result in considerable and detrimental effects for an asset owner or manager’s triple bottom line. Dust, potholes, rutting, corrugation and other surface degradation caused by heavy traffic or extreme weather can cause serious harm to people, the planet and profit.

GRT9000 polymer soil stabilization helps alleviate these environmental, social and financial concerns. Using in-situ or imported materials, GRT9000 is used to create a hard, semi-flexible and water impermeable pavement. Mitigating against pavement and surface degradation, GRT9000 is designed to treat:

  • Natural or manufactured granular pavement materials
  • Insitu recycled pavements
  • Subgrade materials such as clays, silts and sands

GRT9000 polymer soil stabilized pavements display high bearing and tensile resistance, and pose a cost effective alternative to traditional bound pavements such as asphalt and concrete – for a laid pavement saving from 50-70%. This polymer treated pavement can be used to design and construct:

  • Haul roads
  • Rural and farming roads
  • Service roads and hardstands
  • Base and sub-base layers of major public roads and infrastructure

Independently verified as environmentally sustainable, GRT9000 can also be used to improve the performance of traditional cementitious stabilising agents. This can reduce the quantity of cement or lime required in pavement designs, or completely replace them.

Polymer Seal

(Environmental)


A specially formulated liquid polymer, GRT7000 is a key solution that dries clear, and is environmentally friendly. Engineered for use in civil construction, it can act as a clear polymer sealant as well as a high performing stabilization agent.


GRT7000 (D) Dust Control Polymer Sealing:

Polymer sealing with GRT7000 works differently. After initial works, maintenance applications are required once every 12 to 16 week depending on traffic loading. With each application, an accumulating number of silty dust particles are bound together, preventing them from becoming airborne. Due to the cumulative residual nature of the product, over time, the rate of application of GRT7000 reducing, becoming more economical each year. Simply sprayed from a water truck, the results are:

  • Elimination of dust and its impacts (visibility, health, surrounding areas)
  • Stable, waterproof surface preventing corrugation and potholing
  • Improved skid resistance and decreased rolling resistance
  • Costs savings of 30-40% due to removal of daily watering and grading, less wear and tear on vehicles, improved haul times, elimination of downtime during and after wet weather (cost savings independently verified by Deloitte).
  • Available is environmental Green and environmental Clear product color

GRT7000 (S) Soil Stabilization:

As well as a clear, environmentally safe, and aesthetically pleasing polymer seal, GRT7000 is a highly effective polymer soil stabilization agent. Used on its own or in conjunction with traditional soil stabilisation agents it achieves extremely high UCS results with relatively low dosage rates. For example, testing with as little as 0.7% by mass has seen results over +6MPa achieved.


Applications:

The key areas of use for GRT7000 as a polymer seal and/or stabilization agent are:

Pothole Patch


GRT4000 is a revolutionary polymer solution used to repair a wide variety of road failure types from filling small potholes to large continuous patches. Repairs can be made in granular pavements with a variety of different surface treatments and can be engineered as temporary or permanent repairs. Additionally, it is the only consistently successful approach to patching in unsealed roads.


Saving Time, Money and Resources.

GRT4000 is mixed with water and locally available granular materials, the existing in situ pavement, or manufactured road base. The polymer is added to the “squared up” damaged area where it bonds with the surrounding material, creating a semi-flexible and water-resistant patch proven to last as well as the original road.

Areas repaired with GRT4000 are more cost effective than traditional patching materials, whilst still being resilient and semi-flexible. Achieving full strength quickly, the treated area remains intact and stable through extreme weather conditions, including heavy rains and high-temperatures.

Best of all, roads repaired using GRT4000 can be used almost with minimal delays after the repair has been made, minimising disruptions to road users and improving maintenance productivity.
