TerraGrid® Asphalt Reinforcement Geogrid

Product Code: 1000011

TerraGrid® polyester asphalt reinforcement composite geogrid, offering exceptional results with preventing reflective cracking in asphalt overlays.

Description

TerraGrid 6060C provides the best solution to prevent reflective cracking in asphalt overlays. It combines a high modulus polyester geogrid with a lightweight non-woven. This product is coated with bitumen to strengthen the bond with the asphalt layers. This increases the tensile strength and results in reducing tensile stress peaks.

As TerraGrid 6060C displays similar thermal expansion properties to asphalt, reflective cracking is reduced. This results in lower maintenance costs and extends the service life of the overlay.

TerraGrid® 6060C is manufactured in accordance to ISO 9001:2008

Applications

While an asphalt geogrid, it can also be used for:

  • Reinforcement of granular soils
  • Embankment reinforcement
  • Retaining structures
  • Basal reinforcement
  • Piling platforms
  • Subgrade improvement

Installation Guidelines

Recommendations:

  • Apply on a firm, even, dry, dust free swept substrate
  • If a regulating course is specified, use a mix of 5mm maximum aggregate size
  • Use a <0.5litre/m2 bituminous bond coat. If emulsion based, adjust spray rate to take water content into account
  • Make sure the emulsion is sufficiently viscous to avoid run offs
  • Leave sufficient time for the bond coat curing if it is emulsion based
  • Lay a minimum asphalt layer thickness of 30mm in one pass above the grid.

Surface Preparation

The surface onto which the TerraGrid C is to be laid should be even, dry and free of dust and other loose materials. Cracks wider than 10mm should be filled with a suitable sealant. Finely milled surfaces are acceptable for the installation of TerraGrid C; however, coarse or unevenly milled or broken surfaces should be regulated with a suitable fine (maximum aggregate size: 6mm) sand asphalt mix.

Specifications

Applications

  • Asphalt reinforcement
  • Reduce reflective cracking
  • Prevent traffic induced shearing
  • Extend pavement life
