The Process of Installing Asphalt Speed Bumps

Speed bumps are one of the best ways to ensure that drivers drive at safe speeds. They are especially useful in residential areas where the pedestrian concentration is higher. Having an asphalt speed bump installed on your driveway, parking lot, or private road can be a great way to control the driving speeds around your property. Furthermore, asphalt speed bumps are the most common type of speed bumps installed today due to their durability. In this article, we discuss step by step the processes involved in constructing an asphalt speed bump.

Mark Up Your Area for speed bumps

You need to be very specific on where, and how long you want your speed bump to be before you start laying down any asphalt. It is for this reason that it is essential to ensure you properly mark up the perimeter of your speed bump. Usually, a speed bump is 1-3 feet wide and 3-4 inches high. However, this can vary depending on the contractor and customer preferences. Ensure when you are measuring and marking up the asphalt speed bump, you leave a one-foot distance between the speed bump and the bump on both sides to ensure water flow is not interrupted by the asphalt speed bump.

After your perimeter is marked, sweep up the area of any debris and dirt.

Sawing

The next step in the asphalt speed bump installation process is to create a notch on your asphalt road to allow the speed bump to integrate with the asphalt surface. Using an asphalt saw, create a 2-inch wide notch around the perimeter of the speed bump, creating an edge inset.

Lay Down your Asphalt and Build your Speed Bumps

Before you even begin to lay down your asphalt, you need to apply a layer of tack oil to the perimeter of the bump. This will improve the bonds between the asphalt on the road surface and your asphalt speed bump to ensure it stays in place.

Next, you want to put down your first layer of asphalt and tamp it down firmly. This will ensure the eventual speed bump settles in well. Once the first layer is firmly tamped down, continue layering in more asphalt and using a speed bump lute form and shape the speed bump. After the asphalt speed bump has been shaped according to specifications, tamp and compact the speed bump using a hand tamper or a static roller to ensure the asphalt settles down, and there are no air pockets in the speed bump.

Leave the Asphalt Speed Bumps to Cure

Once your bump is dry, you need to give it enough time to cool down and dry. Ensure you prevent any traffic from going over the speed bump until it fully dries. Give it at least a day to make certain, the speed bump is dry and solid enough to handle the traffic.

Final Touches

Once the asphalt is fully dry, you can strip it with paint to ensure that drivers can easily see it. Remember, you want to slow down traffic, not endanger it. To provide more protection for your asphalt speed bump, you should seal coat it to protect it from sun and water damage. We recommend you wait 30 days after installation before seal coating your speed bump.
