Unpaved Roads.
Lotrak® geosynthetics provide effective solutions for the construction of unpaved roads, haul roads, site access tracks, forestry roads, working platforms and infrastructure developments. When building over weak or variable ground, achieving the necessary performance often requires significant aggregate thicknesses, increasing both cost and environmental impact.
The long-term performance of an unpaved road depends on maintaining the integrity of the aggregate layer and preventing contamination from the underlying soil. Lotrak® geosynthetics can provide separation, filtration, reinforcement and stabilisation functions to support road performance throughout its service life. By improving load transfer through the foundation layer, Lotrak® solutions can help reduce rutting, improve trafficking capability and potentially reduce aggregate thickness requirements compared with unreinforced construction.
• Reduced aggregate requirements
• Lower haulage and construction costs
• Improved access over weak ground
• Enhanced road performance and service life
• Reduced environmental impact through more efficient use of materials
Lotrak® biaxial geogrids. are designed to improve aggregate layer performance by creating a more stable foundation layer. By enhancing aggregate stability within the pavement structure, traffic loads can spread more effectively through the foundation while helping to limit rutting and surface deterioration. Our geogrid solutions can accommodate a wide range of aggregate gradings, including larger stone sizes up to 125mm. This gives designers and contractors greater flexibility when selecting construction materials and can create opportunities to utilise locally available or site-won aggregates where suitable.
The ability to work with a broader range of aggregate materials can help reduce imported stone requirements, delivering both economic and environmental benefits.
Unlike single-product systems, Lotrak® offers a complete geosynthetics portfolio. Our technical team can assess whether a woven geotextile, nonwoven geotextile, biaxial geogrid, or a combination of products will provide the most efficient solution for your project. This ensures designs are based on site requirements rather than product limitations. Woven geotextiles can provide robust separation and reinforcement, helping maintain aggregate thickness and performance over weak subgrades. Nonwoven geotextiles offer effective filtration and separation where drainage considerations are critical, while biaxial geogrids can enhance aggregate stability and load distribution within the pavement structure.
Our Stronger by Design approach allows us to develop project-specific solutions using either high-strength woven geotextiles, biaxial geogrids, or a combination of both, ensuring the most appropriate solution for the site, the client and the environment.
Lotrak® Woven Geotextiles
Designed to provide excellent separation and reinforcement performance within road foundations, helping preserve aggregate integrity and maintain pavement performance.
