Jersey barriers, also known as concrete median barriers, come in several types designed for specific applications. These types differ primarily in their dimensions, the materials used, and their intended use, whether for permanent installation or temporary detours.
The standard type is a cast-in-place or precast concrete structure. It is typically 10-12 inches high and 24 inches long. Standard barriers are often seen on construction sites or along highways to redirect traffic.
Test Level 2 (TL-2) and Test Level 3 (TL-3) barriers are designed and approved by the Federal Highway Administration (FHWA) for safety on medium-speed highways. TL-2 barriers are used on roads with speeds between 43-70 mph. TL-3 is for roads up to 70 mph with more heavy vehicles. They can resist impact while effectively redirecting traffic.
This type is designed to be more durable and resistant to environmental factors. Therefore, Stainless steel barriers cost stainless steel, which is more expensive than concrete. They are often used in coastal areas, extreme weather regions, and high-security zones.
These are usually made from high-density polyethylene (HDPE)but can also be concrete. The primary advantage is that they are light and can be filled with water or sand for added stability. Water-filled barriers are temporary solutions, ideal for short-term needs, such as construction sites.
The reversible jersey barrier helps save space on narrow roads or construction sites. One side is sloped to deflect oncoming traffic, and the other side has a vertical face for containment. This design allows the barrier to be flipped over, providing versatility for changing traffic conditions.
The barriers play a vital role in both industrial and commercial settings. It ensures safety, enhances security, and manages traffic effectively.
Jersey barriers direct vehicles through industrial zones, ensuring they follow designated paths. These barriers help minimize the risk of accidents by preventing unauthorized vehicle access to hazardous areas, such as chemical storage, heavy machinery zones, and loading docks.
In industries like construction and manufacturing, there will be active work zones with ongoing projects. Workers can be protected from traffic-related accidents by using Jersey barriers to separate vehicles from these work areas.
This is especially important for outdoor industrial operations where heavy equipment, workers, and vehicle traffic co-exist.
For large warehouses with busy loading docks and delivery areas, jersey barriers can manage truck and car traffic. This management ensures vehicles enter and exit loading docks safely without posing a risk to workers or damaging warehouse equipment.
Cement barriers are commonly used to secure industrial facilities such as factories, chemical plants, and warehouses. These barriers help ensure only authorized personnel enter these high-security areas.
When installed around the perimeter, concrete barrierscan prevent theft, vandalism, or unauthorized access. This reduction of security breaches helps industries maintain safer operations and protect sensitive materials or technology.
Some of the following factors should be considered when choosing the best jersey barrier for the buyer.
The material for making the barrier should be what is suitable for the environment and the durability needed. Concrete barriers are more durable and heavier, making them suitable for on-risk roads.
The types of barriers are classified as permanent and temporary. Buyers should understand industrial needs before purchasing a barrier. Permanent barriers are for long-term traffic management. Temporary barriers are for short-term needs.
The barriers' outdoor and indoor use will determine the materials used to make them. UV-treated polyethylene plastic barriers are suitable for outdoor use. Indoor barriers are usually made of lightweight materials for easy transport.
The size and weight of the barrier should be appropriate for the area being secured. Concrete barriers are heavier and more massive, making them suitable for high-traffic highways. Water-filled barriers are lighter and easier to relocate.
Water-filled barriers and plastic barriers are temporary and suitable for low-risk security areas. Permanent barriers like reinforced concrete will be more suitable for high-security areas.
Permanent barriers are usually more expensive due to the materials used. Water-filled barriers are affordable. However, they are only a good long-term solution for low-risk areas.
A. Jersey barriers contain and redirect the vehicle away from the accident point. This feature helps prevent damage to pedestrians, property, and infrastructure.
A. Yes, they can be integrated with other traffic control measures like warning signs, cones, and fencing to provide comprehensive safety.
A. Yes, especially the water-filled ones. The water-filled ones can be removed, allowing the surrounding ecosystems to remain undisturbed. Reinforced concrete can also be recycled for other purposes.
A. The highways' speed, traffic volume, and types will determine which type to use. For high-speed highways, the security barriers should have higher standards like the TL-3 barrier.
