Tenax RoaDrain®

RoaDrain® roadway drainage geocomposite, engineered to improve drainage and/or frost heave potential, incorporates a compressive resistant, void-maintaining drainage system into the pavement structure. RoaDrain® is manufactured by fusing a medium weight nonwoven geotextile to a Tri-Planar Core. The Tri-Planar Core gives RoaDrain® its high compressive strength, minimizing geotextile intrusion enough to maintain a significant air void to provide a positive capillary break. RoaDrain® has excellent fluid transmission characteristics, equivalent to free draining base materials, it is readily available and installs quickly and easily.

 

Used Under Rigid or Flexible Pavements, RoaDrain® Can:

• quickly remove subsurface water from the pavement
• effectively separate structural fill from the native soil
• reinforce the base course and restrain a weak subgrade
• provide a positive capillary break
• reduce damage from frost heave and subsequent thaw

 

Installed under the base aggregate, RoaDrain® significantly shortens the drainage path. The improved drainage provided by RoaDrain® increases the structural support of the pavement system, increasing the life and/or performance of the pavement. RoaDrain® provides rapid removal of water. Placed directly beneath the pavement surface, RoaDrain® collects any infiltrating water before it enters the base. At a lower depth, under frost-susceptible soils, RoaDrain® acts as a capillary break and helps eliminate frost heave.
