Tensar AR-GN Asphalt reinforcement geogrid
Tensar AR-GN is a composite, comprising a geogrid thermally-bonded to a fabric that together provide reinforcement and act as a Stress Absorbing Membrane Interlayer (SAMI) and moisture barrier, once saturated with bitumen during installation.
Typically installed under the binder course or the base course layers, AR-GN’s high profile geogrid mechanically interlocks and confines asphalt layers to restrict lateral movement of particles.
The reinforced layer created prolongs service life, by offering incredible resistance to reflective cracking and mitigating longitudinal cracking caused by differential settlement between new and existing lanes on widened roads. It can also reduce surface rutting, particularly in low stiffness asphalt mixes subjected to slow and heavy wheel loading at high temperatures.
Perfectly suited to overlaying flexible rural roads with low stiffness foundations or those susceptible to soil weakening through spring thawing, AR-GN can reduce overlay thickness by up to 30%, when compared with unreinforced overlays.
- Controls reflective cracking and mitigates differential settlement cracking between new and existing lanes on widened roads
- Reduces surface rutting by restricting lateral movement of particles
- Extends operational life by delaying the onset and development of cracking, delivering long-term cost savings compared with traditional methods
- Can reduce overlay thickness by up to a third.

Tensar’s pavement optimisation and asphalt reinforcement solutions introduce a different kind of thinking to road design and repair, taking a longer term view to optimise performance and reduce initial and whole-life costs.
With its four key pillars, Tensar Road Technology allows you to achieve the necessary performance and efficiency from every road project, whether new-build or refurbishment
