Installing plastic speed bumps is a simple process that can be done quickly and easily. Plastic speed bumps are an effective way to reduce traffic speeds and increase safety for motorists and pedestrians. They are extremely simple to set up, requiring minimal disruption to traffic flow and no large set of specialized tools for installation. The process involves marking the desired location, drilling bolt holes, cleaning and drying the area, inserting anchors, and then placing the speed bump so that the bolt holes align with the drilled holes. Finally, bolts are inserted and tightened, and epoxy can be used to protect older asphalt from cracking. It is important to ensure the work area is clear of any obstacles and to wear protective gear during the installation process.

What You'll Learn

Preparing the ground
Firstly, it is important to clear the area of any significant potholes or other abnormalities in the roadway. This step ensures that the speed bump will sit flat on the surface and is crucial to prevent damage when vehicles drive over it. It also helps to inspect the ground for any cracks or damage and, if found, these should be repaired to create a smooth and stable base.
Once the ground is level, the next step is to mark the desired position of the speed bump. This involves placing the speed bump in the chosen location and marking the pavement inside the bolt holes with chalk. These markings will guide the drilling process, so it is important to ensure they are accurately placed. After marking, remove the speed bump temporarily to prepare for the next step.
The next phase involves cleaning and drying the marked area. This step is important to ensure that dust, debris, and any other residue are removed, creating a clean surface for drilling and installation. Use a brush or blower to remove loose debris, and then a dry cloth or industrial vacuum to ensure the area is free of dust.
After the area is cleaned and prepared, the next step is to drill the markings to create bolt holes. Using a suitable drill bit, drill through the pavement at each chalk marking. This step requires care and accuracy to ensure the holes are straight and aligned with the markings. Once the holes are drilled, the area should be cleaned again to remove any debris created during the drilling process.
Finally, the anchors can be inserted into the drilled holes. Tap them gently with a hammer until they are flush with the surface. It is important to ensure that the anchors are secure and firmly in place before proceeding to the next step of attaching the speed bump.

Positioning the speed bump
Firstly, ensure the work area is clear of any obstacles and abnormalities in the roadway, such as potholes. All dust and debris should be removed to ensure a secure installation. This is important for the safety of the workers and to protect the speed bump from damage.
Next, place the speed bump in the desired location. It is important to consider the context and purpose of the speed bump. For example, is it to reduce traffic speeds in a busy area with a lot of pedestrians? Or is it to slow down vehicles in a residential area? Place the speed bump where it will have the greatest impact on traffic speed and where it is most important to improve safety.
Once you have decided on the location, mark the pavement inside the bolt holes with chalk. This will help you to know where to drill. Remove the speed bump and drill each marking to create bolt holes. It is important to clean and dry the area before inserting anchors into each hole. Tap the anchors with a hammer until they are flush with the surface.
Now you can reposition the speed bump so that the pre-sunk bolt holes align with the drilled pavement holes. The bolt holes should sit directly above the drilled holes. Finally, insert bolts with washers through the bolt holes. Tighten each bolt, starting with the center one, until it is 3/4 submerged. Then return to each hole and tighten until snug.

Drilling and cleaning
First, put on the appropriate protective gear, including safety gloves and steel-toe boots, to ensure your safety during the installation process. Next, clear the work area of any obstacles, dust, or debris. This step is essential to ensure a secure installation. Once the area is clear, position the speed bump in the desired location. Mark the pavement inside the bolt holes with chalk, then remove the speed bump.
Now, it's time to start drilling. Drill each marking through the pavement to create bolt holes for the steel spikes. After drilling, clean and dry the area thoroughly. This step is crucial to ensure a strong and secure installation. Any residual dust or debris could weaken the bond between the speed bump and the pavement. Once the area is clean and dry, insert anchors into each hole, tapping them gently with a hammer until they are flush with the surface.
The drilling and cleaning process is an important step in installing plastic speed bumps. It ensures that the speed bump is securely attached to the pavement and helps to create a smooth and flush finish. By taking your time and following these steps, you can ensure a safe and sturdy installation.

Hammering in spikes
Once you have marked the desired location of the speed bump with chalk, drilled the markings, cleaned and dried the area, and inserted anchors, it's time to hammer in the spikes.
First, reposition the speed bump so that the pre-sunk bolt holes align with the drilled pavement holes. Then, starting with the center bolt hole, hammer in a spike until it is snug against the counterbore hole. Repeat this process for each bolt hole, making sure to hammer the spikes until they are snug against the counterbore holes.
It is important to wear safety gloves and steel-toe boots when hammering in the spikes to protect yourself from potential injuries. Additionally, make sure that the work area is clear of any obstacles and that all dust and debris have been removed before starting the installation process.
After all the spikes have been hammered in, butter the spikes with epoxy to help protect older asphalt from cracking. This step will ensure the longevity of the speed bump installation.

Final tightening
First, ensure that the speed bump is correctly positioned, with the pre-sunk bolt holes aligned with the drilled pavement holes. Insert the bolts with washers through the bolt holes. Begin with the center hole and tighten each bolt until it is 3/4 submerged. Then, return to each hole and tighten until snug. It is important to follow the correct sequence when tightening the bolts to ensure even pressure and to avoid any warping of the speed bump. Work in a circular pattern, moving from the center out to the edges, tightening each bolt incrementally.
For the final tightening, use a torque wrench to ensure the bolts are securely fastened. This will give you an accurate measurement of the bolt tension. Tighten each bolt to the manufacturer's specifications, which will depend on the size and type of speed bump. Over-tightening can strip the threads or damage the speed bump, so be sure to follow the recommended torque settings.
Finally, inspect the speed bump to ensure that all bolts are secure and properly tightened. Check that the speed bump is level and flat, with no warping or unevenness. Any imperfections in the installation could lead to damage or reduce the lifespan of the speed bump.
