GRT Fast Facts

Speed

Speed

The time it takes to build a GRT road is significantly less than a conventional road. Saving considerable materials, money and water a skilled crew can lay between 6,000 to 10,000 sq. metres of road per day.

GRT products are applied quickly with roads operational within hours. Reducing traffic disruption, GRT roads are ready to use within days of initial planning.

Strength

Strength

GRT roads are robust, resilient and flexible. Just as strong in wet, dry, hot and cold conditions, they accommodate movement, moisture and temperature that crack pavements stabilised with traditional methods. A GRT treated pavement offers designers with unique engineering properties that can yield a 70% reduction in overall pavement depth compared to untreated materials. UCS values of greater than 6 Mpa normally only considered in ridged pavement design can have greater utilisation due to tensile strengths of up to 25% of compressive strength. Resilient module’s values of >5000 MPa, akin to deep-lift asphalt enable flexible pavement design principles to be adopted.

Cost

Cost

GRT roads present both short and long-term cost benefits. Lowering application and labour costs, they promote longevity and lower maintenance expenses.

Incorporating in-situ materials, GRT roads do not require external materials such as newly quarried road bases or manufactured products such as asphalt or concrete significantly reducing transportation and material costs.

Machinery

Machinery

During application, GRT treated in-situ roads and hardstands require only a stabiliser, water truck, grader and roller. This simplified process negates the need for other pieces of equipment such as; powder tankers, spreader trucks and tip trucks.

GRT treated roads require less maintenance which saves on machinery purchase, hire and maintenance, as well as overall running costs such as fuel and tyres.

Speed

Application

Construction procedures are simplified with GRT’s innovative range of polymer products. GRT products can be mixed with salt or fresh water and applied using only a water truck, grader and roller, where sophisticated stabilising machines are not available. For maintenance activities such as fixing potholes, all that’s required is a shovel, wheelbarrow, and polymer product. Given the simplified application processes, low-skilled labour can be utilised – essential in rural communities where expert road construction crews are not always readily accessible.

Environmentally Friendly

Environmentally Friendly

GRT’s range of polymer products has been independently verified as environmentally friendly by ERM. Significantly reducing the water used for dust suppression and road maintenance, they present a low carbon footprint option.

Nothing is wasted when building a GRT road. If a road needs to be built or changed, in-situ material, including old roads, is simply broken-up and incorporated into the new road.

With little or no external materials required during the construction of most GRT roads, there is a large reduction in truck movements, reducing greenhouse gas emissions.

Maintenance

Maintenance

Damage to either traditional or GRT roads is cheaper and easier to repair using GRT’s innovative products and processes. No heavy machinery is required to treat repairs – it can be as simple as a watering can, shovel, compactor and wheelbarrow. Repairs are made quickly, last as long as the original road and will not delamination. Furthermore, repaired roads are operational within minutes, not days, limiting traffic delays.

Transport

Transport

GRT’s full range of innovative, polymer products are easily transportable in Intermediate Bulk Containers (IBCs). Predominately sold and transported in a concentrate form and diluted with water prior to application, GRT’s specially engineered formulations can be transported in IBCs in the back of a utility vehicle or small truck. IBCs are stackable and designed to be moved using a standard forklift or a pallet jack.

Safety

Safety

Safety is the foundation of GRT’s polymer sealing, dust suppression and road stabilization products. Minimizing dust, GRT’s polymer solutions help combat visibility issues on site and in local communities. They also protect workers and members of local communities from respiratory health concerns associated with fugitive, airborne dust. GRT’s stabilization polymer products enhance safety by mitigating erosion and subsidence issues as well as providing non-slip, waterproof surfaces on most soil types. They are also safer for workers than bitumen, asphalt, and cement due to the product’s very low toxicity and are applied at ambient temperatures.

ROAD TRAUMA: THE FACTS

The United Nations declared 2011-2020 the Decade of Action for Road Safety in response to the mounting human tragedy of deaths and injuries on roads worldwide.

THE HUMAN TOLL OF ROAD TRAUMA:

GRT Polymer Technology

The use of GRT polymer technology in the construction industry is steadily growing. The synergetic action of GRT polymers offers great opportunities for improvement and a wide range of new and innovative applications.
The use of polymers should be well considered to guarantee better performance and improved sustainability.

Polymers are no longer special construction materials that replace classical mineral or organic building materials. They are now one vital component in the production of composite and sustainable building materials. They will further allow the development of new and durable constructions, as well as new durable restoration and retrofitting techniques.
