Let’s first begin by understanding what crash barriers are.

What Are Crash Barriers?

---

Crash barriers are safety devices designed to reduce the impact of a collision, which in return protects people, equipment, and infrastructure from serious damage.

You would find crash barriers most commonly on highways, but they are also used in industrial settings, where there is a high usage of large equipment and machinery.

By using various crash barrier types, depending on the setting, you can prevent vehicles or machinery from causing significant damage when they veer off course. Now that you know what crash barriers are, let’s have a look at crash barrier types.

Types of Crash Barriers in Infrastructure Industry

---

When it comes to crash barrier types, there’s no one-size-fits-all solution. The type of barrier you will need to choose depends on the project you are working on, its complexity, level of protection required and the specific environment.

Here we have listed some of the most common types of crash barriers -

1. Rigid Barriers (Non-Deformable)

One of the most common and widely seen crash barriers is rigid barriers. They provide the maximum resistance to impact and do not deform upon collision. Rigid barriers are ideal for highway projects, including the goal of preventing vehicle penetration.

There are two main types of rigid barriers – concrete barriers and bridge parapet barriers. Here’s a quick brief about both of these crash barrier types -

• ● Concrete Barriers: This type of crash barrier is made from reinforced concrete, and they are commonly used on medians and roadsides to prevent crossover accidents.

• ● Bridge Parapet Barriers: Installed on bridges and elevated roads, these barriers prevent vehicles from falling off and provide structural reinforcement.

2. Semi-Rigid Barriers (Partially Deformable)

Semi-rigid barriers are designed to absorb impact energy while deflecting slightly to reduce crash severity. There are two main types of semi-rigid barriers – W-beam guardrails and thrie-beam guardrails.

• ● W-Beam Guardrails: One of the most widely used highway safety barriers, W-Beam guardrails feature a corrugated steel design that absorbs impact while redirecting vehicles back onto the road.

• ● Thrie-Beam Guardrails: A stronger and wider version of the W-beam, Thrie-beam guardrails provide enhanced impact resistance which is particularly useful for high-speed highways and heavy vehicle traffic.

3. Flexible Barriers (Highly Deformable)

Moving next, flexible barriers can be a great choice when you want to have a solution that absorbs maximum energy by deflecting significantly upon impact, reducing the risk of severe injuries and vehicle damage.

Here are two sub-types of flexible barriers -

• ● Cable Barriers (Wire Rope Barriers): These are made of steel cables mounted on posts and are commonly used on medians to prevent head-on collisions.

• ● Plastic Water-Filled Barriers: If you are working on a highway project that includes temporary roadwork zones, plastic water-filled barriers should be your go-to choice. They are easy to install and as they are filled with water, they offer a controlled impact resistance while remaining portable.

4. Crash Cushions (Impact Attenuators)

Lastly, crash cushions, also known as impact attenuators, are designed to absorb and dissipate impact energy which in result reduces crash severity and protects both vehicles and road structures.

Here are two sub-types of crash cushions -

• ● Sand-Filled Barrels: They are often placed at highway exits, toll booths, and construction zones and they absorb impact by dispersing sand, reducing collision force.

• ● Energy-Absorbing Terminals: Installed at the ends of guardrails, these terminals minimize the risk of vehicles penetrating through barriers, enhancing road safety.

There’s no doubt that each of these crash barriers serves a specific purpose, depending on road conditions, traffic volume, and safety requirements. By assessing your own requirements, you can make the right choice of crash barriers for your highway projects.

How to Choose the Right Crash Barriers?

---

To select the right crash barrier for your project, you will need to consider a few key factors as discussed below -

• ● Risk Level: The first thing you need to consider is the level of accident probability in your area. If your project is near a highway or high-traffic zones, you’ll need something more robust, like a W metal beam barrier.

• ● Environment: Secondly, you will also need to consider harsh weather conditions while choosing crash barriers for your highway projects. It’s highly recommended to choose metal beam barriers as they are durable and built to last.

• ● Impact Resistance: Another factor you should consider while choosing a crash barrier is impact resistance. If your project is being developed in areas where high-impact collisions are a possibility, you will need to have stronger barriers like W metal beam barriers. For example, if the highway you are working on has sharp turns or steep declines, you will need to have barriers with great resistance to minimize vehicle penetration.

• ● Industry Requirements: Moving next, it’s also recommended that you understand the minute details of your project. For instance, highways with heavy commercial truck traffic may require reinforced barriers to withstand greater force, whereas urban roads might prioritize barriers with pedestrian safety features.
  
  When you have an understanding of your industry's needs it will help you select the most appropriate barrier system.

• ● Visibility: Next, you also need to make sure that crash barriers you select are easily visible, especially in low-light conditions or adverse weather.
  
  Crash barriers with reflective strips, painted surfaces, or built-in lighting elements improve visibility so that drivers can easily spot them and adjust their driving accordingly.

• ● Ease of Installation and Maintenance: Moreover, the installation process of crash barrier should be efficient, especially for large-scale highway projects.
  
  Barriers that require minimal groundwork and can be quickly assembled help you and your team save time and money. Additionally, selecting low-maintenance materials, such as steel or concrete, ensures long-term durability with minimal maintenance.

• ● Compliance with Regulations: It is essential to choose crash barriers that meet national and international safety standards. Make sure you are using crash barriers that meet national and international standards of regulation.

• ● Cost-Effectiveness : While safety is the primary concern, budget constraints also play a role in choosing the right crash barrier. It’s recommended that you choose barriers that offer the best balance between cost, durability, and performance.
