    Highway guardrail AASHTO-M180

    A guardrail, also known as a crash barrier or safety barrier, is a protective barrier designed to prevent vehicles from straying off the road or colliding with obstacles. Guardrails are commonly used on roads and highways, as well as on bridges and in parking lots, to help ensure the safety of drivers and passengers.

    Guardrails are typically made from materials such as steel, aluminum, or concrete, and they can be either rigid or flexible, depending on the specific application and the desired level of impact resistance. The most common type of guardrail is the W-beam guardrail, which consists of a series of steel posts supporting a horizontal steel rail in the shape of a "W".


      In addition to the traditional W-beam design, there are also other types of guardrails, such as the box beam guardrail, the cable barrier, and the jersey barrier. Each type of guardrail has its own unique design and characteristics, and the choice of guardrail will depend on factors such as the location, the speed of traffic, and the potential for collision.


      Guardrails are typically installed along the edges of roads and highways, and they are designed to absorb the impact of a collision and redirect the vehicle back onto the road, minimizing the risk of injury or damage. Guardrails are also used to protect pedestrians and cyclists, as well as to separate lanes of traffic and prevent vehicles from entering restricted areas.

      Overall, guardrails are an important safety feature on roads and highways, helping to prevent accidents and protect drivers and passengers. They are designed to be durable and long-lasting, and they play a crucial role in maintaining the safety of the transportation infrastructure.
