RoaDrain™ Roadway Drainage System
- Synthetic subsurface drainage layer
- Superior separation and filtration
- Resists deformation
- Lower material costs
- Faster installation
The RoaDrain™ roadway drainage system provides a synthetic subsurface drainage layer (SSDL) that outperforms traditional open-graded base layers (OGBL) and exceeds standards set for typical stone drainage layers.
The RoaDrain system increases the flow rate by 500%, quickly removing water and decreasing overall drainage time. It provides “excellent” drainage as defined by AASHTO (50% water removal from a pavement structure within two hours), which significantly extends pavement life and reduces maintenance costs. You can also save on material costs with a reduction in processed structural fill quantities and accelerate your construction schedule with a faster installation time.
The RoaDrain system’s unique properties and performance stem from its construction. It features durable, nonwoven geotextile fibers laminated to the top and bottom of a tri-planar geonet core. The geonet core provides a void-maintaining structure with high compressive strength that resists deformation. While the geotextile material offers superior separation and filtration of fines and other materials.
The RoaDrain system is available in two SKUs: RD5 and RD7.
