EPS Foam and Its Applications

The video explores the use of expanded polystyrene (EPS) foam, commonly known for packaging, in road construction. EPS foam is used to replace unsuitable soil in road projects, providing a lightweight yet durable solution. The installation process involves stacking layers of geofoam, covering them with a rubber membrane, and adding soil and asphalt. A demonstration shows EPS foam's strength, capable of supporting heavy loads. The video also briefly touches on a creative arcade trick from the past.
