Asphalt Reinforcement

Asphalt reinforcement aims to reduce reflective cracking in asphalt surfacing over cracked substrates such as joints in underlying concrete slabs or cracks in cement-bound base layers or existing asphalt layers, plus those induced by thermal movement of substrates and traffic-induced shearing.

How Tensar asphalt reinforcement geogrids can help

Tensar’s asphalt reinforcement geogrids and composites interact with the bitumen bound layer to add tensile stiffness, limiting strain and reducing crack development (and when cracks do develop, they are often much smaller). Composites comprise a geogrid bonded to a fabric that together provide reinforcement and act as a Stress Absorbing Membrane Interlayer (SAMI) and a moisture barrier.

Controlling surface cracking with Tensar

Asphalt reinforcement aims to reduce cracking in asphalt surfacing placed over cracked substrates, joints in underlying concrete slabs or cracks in cement-bound base layers, plus those induced by thermal movement of substrates and traffic-induced shearing.

The benefits of Tensar asphalt reinforcement geogrids and composites:

  • Reduced reflective cracking: Asphalt reinforcement can reduce reflective cracking in the asphalt surface caused by the movement, bending and shearing of cracks in underlying asphalt layers or cement-bound substrates. The SAMI effect can also reduce strain in the surface.
  • Control of differential settlement cracking: Combining asphalt reinforcement with Tensar TriAx geogrid in new unbound aggregate layers can mitigate longitudinal cracking caused by differential settlement between new and existing lanes on widened roads.
  • Reduced surface rutting: Asphalt reinforcement geogrids interlock with the asphalt to restrict lateral movement of particles, reducing permanent strains and surface rutting, particularly in low stiffness mixes subjected to slow and heavy wheel loading at high temperatures.
  • Longer operational life: By delaying the onset and development of cracking, Tensar asphalt reinforcement products can increase overall pavement performance and as a result, extend operational life.
