Muhlenberg Count, KY Airport

Muhlenberg County Airport located in Greenville, Kentucky as in need of improvements including a new 2,800 foot partial parallel taxiway. During the design it was discovered that the soils to support the one to three foot taxiway embankment were weak and would create issues with stability. Some method to gain stability of the weak in-situ soils was necessary to allow construction of the embankment.

One method for dealing with unstable soil conditions in embankment construction is to place select aggregate fill
onto a geotextile fabric in an effort to spread the load and "bridge" the unstable soils. Due to the material cost of
geotextile fabric and aggregate as well as labor and hauling costs, the price tag can be quite hefty. In addition, the use of virgin aggregates for this purpose is not the most efficient and environmentally sound use of natural resources. On the other hand, in-place cement modification of unstable soils can provide a quick, cost effective and eco-friendly solution.
