Energy-Absorbing Roadside Barriers Using Bio-Inspired Architecture and 3D Concrete Printing

Researchers at Purdue University have developed an innovative energy-absorbing roadside barrier designed to provide optimal impact resistance while efficiently dissipating energy. This cutting-edge barrier system is specifically engineered to withstand high-impact loads, making it ideal for use in high-speed traffic areas and situations involving large vehicles, such as trucks.

The barrier's unique arrangement enhances its ability to flex upon impact and absorb energy, significantly reducing the risk of vehicle damage and improving safety during collisions. While various impact barriers exist, this novel design stands out due to its distinctive layered structure, ability to withstand high-impact loads, and its superior energy-depilation capabilities. All these features in combination work to ensure better protection for vehicles and passengers in the event of a collision.
