TENAX RoaDrain 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.
Product Highlights: TENAX RoaDrain
Features and benefits:
  • Economic alternative to open-graded aggregate (free-draining base layers)
  • Improved Structural Number (SN) due to improved pavement drainage
  • Reduced undercut
  • High in-plane flow rates mean decreased time to drain
  • True capillary break results in 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 and 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

Applications:

  • Roadways
  • Under aggregate base course
  • Directly beneath PCC or asphalt pavement or pavement overlay
  • PCC joint repair
  • Parking lots and paved walkways drainage layers
  • Embankments and dike drainage
  • Alternate to granular blanket drains
