Enhanced Pavement Performance With Synthetic Aggregate
TENAX RoaDrain Synthetic Aggregate from CONTECH is one of a host of pavement solutions, including base reinforcement, differential settlement control, reflective crack for asphalt overlays, subgrade improvement and waterproofing, that ensure you get the best performance from your pavement.
Features and Benefits of the RoaDrain system:
- Economic alternative to open graded aggregate (Free draining base layers)
- Improved Structural Number (SN) due to improved pavement drainage
- Reduce undercut
- High in plane flow rates / decreased time to drain
- True Capillary Break - Void maintaining structure (for freeze-thaw areas)
- Long term resistance to applied high normal loads
- Compressive Creep Resistance: ~ 70% thickness retained after 10,000 hours at 25,000 psf loading
- Ease & speed of installation
- Ability to use structural fill in lieu of less structural open graded drainage aggregate
- Geotextile separator to prevent the migration of fines
- Energy absorption to mitigate reflective cracking to overlying asphalt
