EPS Geofoam Applications: Road Widening

With population increases comes the inevitable need for roadway widening, as road congestion because a major problem for major throughways. This road widening results in the need for additional fill for the widening process. This can not only be an expensive endeavor, but can be a time-consuming process as well, especially if the soils adjacent to the existing roadway do not offer adequate support to handle traffic loads. Fortunately, there is a cheaper, faster, and more reliable product to help widen roads: expanded polystyrene (EPS) Geofoam.

EPS Geofoam eliminates the need for compaction and fill testing, reduces road construction time, and minimizes impact to existing roadways, as well as adjacent structures and/or buried utilities.

Benefits of EPS Geofoam Use in Road Widening

Thanks to its high compressive resistance, EPS Geofoam is able to withstand induced traffic forces without causing unacceptable loading of underlying soils or adjacent fill. In addition, EPS Geofoam allows you to construct steeper slopes than traditional soil, which, in turn, reduces the amount of additional right-of-way that needs to be acquired.

EPS Geofoam is also an excellent choice when working over pre-existing buried utility lines, such as high pressure gas lines, water mains, and communication cables. Traditional fills and soil can (and do) produce excessive settlement, resulting in exceeded strain tolerances for buried utilities - which can ultimately lead to failure, or worse. Using EPS Geofoam, however, you can eliminate large settlements and avoid expensive - and time consuming - utility line interruption, replacement, or relocation.
