EPS Geofoam Applications: Airport Runway and Taxiways Expanded Polystyrene (EPS) Geofoam can be used for all types of road and bridge construction projects, including bridge abutments and supporting foundations. It is such a versatile material, in fact, that it can even be used in airport construction jobs, as well.Similar to road construction, engineers often rely on EPS Geofoam to replace unsuitable soils underneath airport runways and taxiways. It comes pre-cut into blocks that aren't heavy and don't require any special equipment. Because the material is lightweight but strong, engineers don’t have to worry about overloading the underlying subgrade materials or adding additional load, as other heavier traditional fillers would. A Safer, Cost-Effective AlternativeEPS Geofoam is made up of 98% air, which makes it considerably lighter than soil. However, unlike soil, it doesn’t frost heave. During temperature cycling, it undergoes no loss of structural integrity or other physical properties. This characteristic makes it not only safer but cost-effective due to reduced maintenance.
Because of its closed-cell structure, it is also non-hygroscopic. This characteristic reduces the absorption of moisture and makes it resistant to mold. Airport runway rehabilitation projects aren’t the only construction applications it can be used in, though. EPS Geofoam can be used in new runway and taxiway construction, as well.
