SC Intergrid reinforcement Geotextile
SC Intergrid reinforced
Interlock stiffens the aggregate
Load spread increased
Aggregate transfers load
Performance is improved
Tensioned membrane
reinforced
Geotextile anchored at edges
Load is transferred to geotextile
Geotextile and subgrade
deform
Negligible performance gain

Formpave have carried out
extensive research at
H.R.Wallingford on flow
rates through the sub-
base…
…along with testing at the
TRL, simulating a 60,000
