Limited to a shallow undercut due to existing underground utilities and facing soft soil challenges with a subgrade CBR of 0.9%, Tensar InterAx geogrid with 6” of dense graded aggregate passed proof roll and allowed for the paving of the tennis courts without impacting the existing utilities below.
A temporary construction road to access the rear of a project site. Directly applying Tensar InterAx geogrid to the top of the baby surge, followed by 8” of recycled concrete aggregate to support loaded dump trucks while causing minimal disturbance to the road surface.
InterAx was used to improve load-bearing capacity, eliminate excessive rutting, and mitigate the effects of frost for an existing, damaged roadway due to heavy traffic from agricultural vehicles, worsened by underlying, frost-susceptible organic soils that become weak in saturated Spring conditions.
A driveway and storage yard subjected frequently to heavy equipment and vehicles was experiencing potholes and heavy rutting. Using 6” inches of 57 stone on top of Tensar’s InterAx geogrid provided a stiffer section while reducing future maintenance.
Due to soft soils with CBRs as low as 1.5%, a concern that the underlying soils would cause premature failure for a proposed asphalt pavement under heavy truck loads. Tensar InterAg geogrid with a 14” aggregate base met the long-term goals with minimal maintenance.
