Commercial Paving
Installing an asphalt roadway requires careful planning, preparation, and execution. Here are the general steps to properly install an asphalt roadway:
- 1 Survey and design: Conduct a thorough survey of the area where the roadway will be installed. This includes assessing the existing conditions, determining the required dimensions, and creating a detailed design plan.
- 2 Prepare the subgrade: The subgrade is the foundation of the roadway. It should be properly graded and compacted to provide a stable base. Remove any vegetation, rocks, or debris from the area and ensure proper drainage.
- 3 Install the base layer: Place a base layer of aggregate material, such as item # 4, on top of the subgrade. Compact the base layer using a vibratory roller to achieve the desired density and stability.
- 4 Lay the asphalt: Use an asphalt paver to install a 2 1⁄2 -3 inch binder course on top of the prepared item # 4. Ensure that the asphalt is spread evenly and at the desired thickness. Compact the asphalt using a vibratory roller to achieve proper density and smoothness.
- 5 Apply a layer of tack coat before the second layer of top coat asphalt. Then, install 1 1⁄2-2 inches of type 6F asphalt.
- 6 Apply pavement markings: Once the asphalt has cooled and hardened, apply pavement markings such as lane lines, crosswalks, and symbols as per the design specifications.
- 7 Regular maintenance: To ensure the longevity of the asphalt roadway, perform regular maintenance such as crack sealing, pothole repairs, and periodic resurfacing as needed. It is important to note that the specific installation process may vary depending on factors such as climate, traffic volume, and local regulations. It is recommended to consult with experienced professionals and follow industry best practices for the proper installation of an asphalt roadway.
