Crash cushion eva foam roller barrel is a kind of road guard innovative rotating rails for highway safety, fixed on two sides of roads especially on curves and slopes for preventing vehicles from riding out from roads. It have been successfully deployed in many toll highways and city freeways in China, such as Jinliwen Highway, Longli Highway, Hangxinjing Freeway, etc.
Crash cushion barrel is a hollow cylinder, with heavy SPU skin and EVA foam wrapped with Nylon fibers. The smooth surface and rotating character of crash 
barrel can reduce most of the collision energy, residue energy will be absorbed by foam compression. So such crash cushion barrel can provide maximum railing protection to motor vehicles at dangerous road areas such as steep slope, high embankments, obscure curves, sharp corners to absorb sudden impact during collision, thus minimizing injury to vehicle and passenger. The barrier also acts as a protector for pedestrians along the freeway.
By controlling exit angles crash cushion barrel are able to help accident vehicle skid back onto carriageway. Reflectorized markings and vivid colors on barrels make a significant contribution to freeway safety, especially in conditions of poor visibility at night or rainy days. Cushion barrel can be quickly repaired in case of accidents also.
Features of foam roller barrier
1.A three-dimensional rotating barrel with high intensity reflective
sheeting attached make vehicle protection facilities noticeable and
improves drivers’ visibility to prevent vehicle accidents.
2. The product converts shock energy to rotational energy to prevent
2nd collision accidents and lane departure
3. The product guides an accident vehicle in the moving direction
vehicle to prevent rear-end collisions with following cars.
4. EVA shock-absorbing drugs absorb great shock. EVA has better flexibility and elasticity compared to other polyethylene resins, and the most similar features to rubber; it is lighter than rubber and more elastic than urethane. Therefore, it is not easily damaged.
