Airport Pavement Stabilization
Poor base and subgrade soils can wreak havoc on a roadway or slab, causing a variety of issues such as cracking, rutting and severe pavement settlement. The root of the soil degradation could be caused by:
- Improperly compacted soils beneath the roadway
- Water infiltration through pavement cracks resulting in soil washout
- Roadway widening that did not address soil conditions for new design
- Heavier loads than originally designed for
- Failing sewer systems underneath the pavement causing soil loss
- Zero daytime lane closures
- Removal of remaining viable pavement and poor foundation soils is not required
- Overlay to correct rutting can be performed immediately following the polymer injection into the soils
- Extends the life of a new overlay
- Our hydro-insensitive polymers will push out the water in wet soil conditions while still compacting and densifying the soil
- Compact the loose foundation soils without uneven lifting of the flexible pavement to provide sufficient support of the pavement surface.
- Continued injection into the soils can lift the pavement system if needed.
- Lifting of the rutting is NOT possible.
- Surface cracks will still need to be sealed by traditional methods to mitigate water infiltration into the system.
Delays in airports can cause inefficiencies. Services need to be fast, efficient, and effective. An airport in Southern California had severe inflow infiltration in their stormwater system. The stormwater drains have been leaking, with water infiltration through the joints leading to voids at the surface and the ground subsiding. EagleLIFT's objective: leak seal the underground structure while working from within the drains, (60 in-30 in confined space). Filling voids around the infrastructure and stabilizing the soil with a constant cycle of air ventilation and pumping to prevent water build up. Using a specialized polymer injection process, guns hook to injectors and the polymer reacts just fine in the water in order to solve the airport's problems.
