Geogrid Reinforced Subgrade Influence to Ensure Paved Road Durability

Geosynthetic materials are more and more often used for subgrade reinforcement and/or stabilisation. Geosynthetic reinforcement products used for paved and unpaved roads or traffic areas function on the basis of two mechanisms that contribute to their performance. Shear loads developing in unbound granular layers as a result of traffic loading are transmitted from the base aggregate to the geosynthetic as a result of frictional interaction or via the so called interlocking effect. Depending on the geosynthetic material properties load absorption functions on the basis of frictional interaction and the membrane effect.  It also presents the corrections and additions to improve the existing regulations for use of geosynthetics for road embankments and subgrades to ensure a better paved road durability

Roads, Pavements & Trafficked Areas Reinforcement Geogrid

Lianyi's geogrid technology is utilised for:

• Ground and subgrade stabilisation,

• Capping layer and subbase reduction,

• Improving performance of paved and unpaved roads,

• Increasing bearing capacity of heavy-duty pavements,

• Tensar’s asphalt interlayer products mitigate cracking and improve fatigue life of asphalt surfacing.
