Hiway Group delivers innovative moisture conditioning pavement subgrades across all of Australia and NZ, with a commitment to innovation, environmental sustainability and industry leadership.
Applications
Construction of new pavements
Moisture conditioning of earthworks for residential subdivisions
Moisture conditioning of earthworks for rail, civil and infrastructure projects
Moisture conditioning of earthworks for industrial and commercial developments
Rehabilitation of existing pavements
Benefits
Significantly improved subgrade stability with strength gains of up to 20 times
Cost savings through reduced requirement for imported aggregates and a faster construction time
Reduces risk of costly earthworks fill and subgrade pavement failures
A robust durable platform that eliminates the need for cloth/grid or imported aggregate
Substantially reduces moisture susceptibility
Reduces plasticity making soils easier to work
More uniform earthworks fill and subgrade layer
Encapsulation and remediation of treated contaminated soils
Dries large volumes of water-logged soil instantly
Can be undertaken in any weather conditions
Reduces down-time by enabling earthworks to continue during the earthworks shoulder seasons
Enables reduced pavement thickness and improves earthworks fill and subgrade performance
Moisture Conditioning
Moisture conditioning of wet material using binder is more cost-effective than cut to waste and importation of good quality fill material.
By conditioning wet-of-optimum moisture content soils after a rain episode, earthworks operations can continue immediately, thereby limiting unproductive down-time. Equally, moisture conditioning of dry materials through the controlled injection of water during the mixing cycle is critical in ensuring adequate compaction is achieved during the road construction process.
The Hiway Group operation is very simple and enables large volumes of material to be dried instantly. Our plant is purpose-built to handle almost any ground condition. This enables earthworks to continue without delay and removes the risk of construction delays attributed to quality assurance test failures and rigorous supervision.
Innovation
Hiway Group is committed to delivering solutions with environmental benefits, particularly when considering the treatment of contaminated materials and remediation of contaminated sites to reduce costly excavation and disposal.
