How To Install Speed Bumps In Asphalt

Step-by-Step Guide for Speed Bump Installation on Asphalt

Installing speed bumps on asphalt requires careful planning and precise execution. In this step-by-step guide, I will walk you through the process of marking and preparing the area, laying the asphalt, and cooling and striping the speed bump.

Marking and Preparing the Area: Before you start installing the speed bump, it’s crucial to mark and prepare the area properly. Begin by saw cutting the area, making sure to leave a one-foot distance from the curb or pathway. Determine the desired width and length of the speed bump and mark it accordingly.

Laying the Asphalt: Once the area is prepared, it’s time to lay down the asphalt. Begin by hand tamping the first layer of asphalt to settle it in. Then, gradually add more asphalt to form the speed bump. Use a speed bump lute to shape the bump and ensure a smooth transition. Clean and hand-tamp the edges for a neat finish. Finally, use a plate compactor to further compact the bump and ensure its stability.

Cooling and Striping: After the speed bump is formed, it needs time to cool down before striping. It is recommended to cordon off the area and let the asphalt cool for at least an hour. Once the bump has cooled, you can proceed to stripe it with reflective traffic paint. This will ensure visibility and enhance safety for drivers.

To summarize, installing a speed bump on asphalt involves marking and preparing the area, laying the asphalt in layers, and allowing it to cool before striping. Following these steps will help you achieve a successful installation that promotes traffic safety.

Key Takeaways:

• Installing speed bumps on asphalt can enhance safety and control vehicle speeds.
• Use steel spikes for installing speed bumps on asphalt or gravel.
• Materials needed include a high-speed hammer drill, steel spikes, and activated epoxy resin.
• Proper preparation, including marking and cleaning the area, is crucial for a successful installation.
• Follow safety protocols and wear personal protective equipment during the installation process.

Tips for Successful Speed Bump Installation on Asphalt

When it comes to installing speed bumps on asphalt, there are a few important tips to keep in mind for a successful installation. One crucial aspect is the tack bond between the existing asphalt and the new speed bump. To ensure proper bonding, it is recommended to use liquid asphalt as a tack coat. This helps create a strong and durable connection between the new speed bump and the pavement.

Proper preparation of the existing pavement surface is also key to a successful installation. Before laying down the speed bump, make sure to thoroughly clean the area of any dirt and debris. Additionally, notch the edges of the pavement and fill the inside of the marked area with tack oil. This will ensure a solid foundation and enhance the longevity of the speed bump.

Sealing the adjoining edge of the installation with liquid asphalt is another important step. By doing so, you can prevent moisture penetration and protect the speed bump from potential damage. This simple yet effective measure helps maintain the integrity of the installation and extends its lifespan.

Finally, remember to return to the site after 30 days to apply a sealcoat and stripe the speed bump. This allows the asphalt to fully heal and provides a neat and finished appearance. By following these tips and adhering to safety protocols, such as wearing proper personal protective equipment and cautioning off the work area, you can ensure a successful speed bump installation on asphalt.
