Road Construction


Superior Road Construction Performance

Road construction standards are variable across countries, states, and also industries. These standards are regulated with as much variability – sometimes for the right reasons – sometimes not!

In-situ stabilisation, sealing and dust suppression with our range of speciality road construction products have been used in haul road construction, temporary road construction, highway construction and local road construction.


Superior Roads and Surfaces

When a road is needed for a high volume or heavy traffic area, you need trust in its durability and ongoing performance. Our environmentally-friendly and high-quality road construction products ensure integrity on all kinds of roads; from haul roads to highway construction.

Haul roads are subject to high traffic and heavy machinery such as haul trucks and tracked machinery. Because of this, we have adapted our products to suit this type of road requirement. This focuses on the concept of a maintained pavement, rather than ultimate design principles used in the civil construction industry. A maintained pavement utilises cost effective materials, often won from site, in the road construction process with a focus on cross-fall, drainage and general shape, and maintains quality by:

  • Eliminating dust
  • Minimising watering and regrading
  • Improving water resistant nature of the surface.

Long-term roads, such as public roads, highways or other permanent pavements on private or commercial or industrial land require a different approach. GRT’s products for stabilisation and sealing these roads are:

  • Innovative
  • Cost effective
  • Flexible and durable
  • Sustainable and environmentally friendly


Increased Load Bearing – GRT can improve both the bearing and flexural capacity of your road pavements. Stronger roads can handle a larger number of heavier vehicles for longer, which also drive cost effectiveness and a more sustainable road.

Increased Durability – Stable material in a road means that the road is more durable and performs better over time. Roads built with GRT’s technology ensure longevity in road performance with reduced maintenance costs.

Increased Waterproofing – Water is a roads biggest enemy – across both the coldest and hottest environments on earth. Whether through sealing layers or stabilising the depth of materials, GRT’s products greatly improve the resistance to water ingress, expansion and contraction and associated failure.

Reduced Plasticity Index – Products improve the plasticity index which is indicative of characteristics more like silt or clay, both of which are not ideal for road construction due to their strength or being prone to expansion and contraction
