What are Channelizers

Channelizers are traffic safety products used to alert and direct traffic through roadwork or away from hazardous areas. They are often the orange plastic molded products that you see lined with reflective sheeting. Plastic channelizers are weighed down by a rubber base, varying in shape, size and function. Different channelizers are often used state to state, based on specific regulations. Additionally, all channelizing products are required to meet the guidelines of the Federal Highway Administration.

Types of Channelizers:

Traffic Drums

Channelizer Drums

In the event of roadwork being done in a high-speed area, you will usually see channelizer drums between the worksite and motorist activity. The size of these drums allows for the largest amount of reflective sheeting, making them easily visible to drivers maneuvering through the area. The flexibility of the drums allows them to easily snap back into shape when they take on any damage.

Vertical Panels

Vertical Panels

Vertical panels are used in a similar manner as barrels, but are seen more often when traffic is divided, when there is limited room, or when state guidelines specifically call for them.  They have become increasingly popular as an alternative to the larger channelizing drums since they are cheaper and easier to transport and store.

DelineatorsDelineators

Delineators are another type of channelizer used to guide vehicles through roadwork or hazardous areas. The tall slim design of delineators allows them to be effectively used between lanes of guided traffic, and easily stored.

  Channelizer Cones

Cones are more often used to channelize traffic in slower moving areas, or alongside smaller roadside projects. Generally cones come available in three sizes: 18 inches high, 28 inches or 36 inches and may sometimes include a handle at the top that makes placing and removing them from the roadway easy.

The Difference Between Channelizers, Barriers and Barricades

While channelizers are used to direct traffic, barriers and barricades are used more to restrict it. Barriers are large, heavy, wall-like structures that are used to physically protect workers from traffic.

The purpose of barricades is not to directly protect workers, but to alert drivers. On the road, Type I and Type II barricades are used in work zones while Type III barricades mark closings.

Although the types and uses of channelizers differs slightly between states, they all serve to alert traffic and protect drivers and workers.

How to Install Rubber Speed Bumps

Rubber speed bumps may be regarded as superior to asphalt for a number of reasons: they’re easy to install and remove, they’re less damaging, and they’re cheaper. Although installing a rubber speed bump can be fairly easy, it’s important to do correctly to ensure it stays in place and lasts.

The first step is to make sure that you have all pieces and tools readily available for the installation. Different products have different specifications, so make sure that you have tools that will allow you to follow their specific guidelines. Besides the actual speed bump, your product may have come with either spikes (recommended for asphalt) or bolts and shields (recommended for concrete). Additionally, you will need a drill and hammer for installation.

Tools for Speed Bump Installation

Upon gathering the proper tools, follow these steps:

  • Place the speed bump where you plan on installing it.
  • Drill holes through the designated areas on the top of the bump. Your product should specify the size of your drill bit, matching the size of the spike or lead shield that will ultimately hold the product in place.
  • Remove the bump and re-drill the holes to ensure that they are deep enough. Again, the depth depends on the kind of bump you are installing. Once the holes are drilled, remove any debris from the area. If you are using bolts and shields, hammer the lead shields into the holes before placing the speedbump back into position. Additionally, it may be recommended to fill the holes and layer the bottom of the product with an adhesive.
  • Once the speed bump is back into position over the holes, secure it in place. If you are using spikes, then you will hammer each spike into place. If you are using bolts and shields, then you will tighten the bolt into the shield at this stage. Make sure that the speed bump is as secure as possible to ensure proper usage, and minimal damage. A ratchet may be used to securely tighten each bolt.

Note that it is recommended to remove rubber speed bumps before winter to prevent snow plows from destroying the product. Leave at least a few inches between speed bumps to allow for draining and possible expansion. Most rubber speed bumps are not designed for speeds exceeding 15  MPH.
