Asphalt mix storage is an essential aspect of any asphalt production process. Proper storage ensures the quality and longevity of the mix, leading to more efficient and cost-effective asphalt paving. In this article, we will discuss the best practices for asphalt mix storage.
Choose the Right Storage System
The first step to ensuring quality asphalt mix storage is selecting the right storage system. There are several options available, including vertical silos, horizontal silos, and portable silos. Each type has its own benefits and drawbacks, so it’s important to consider factors such as available space, mix volume, and accessibility when choosing the right storage system.
Maintain Proper Temperature
Maintaining the proper temperature of the asphalt mix is crucial to preserving its quality. The ideal storage temperature for asphalt mix is between 275 and 325 degrees Fahrenheit. If the mix temperature drops below this range, it can become stiff and difficult to work with. On the other hand, if the mix temperature rises above this range, it can become too viscous and lose its workability.
Implement a Quality Control Program
A quality control program should be in place to ensure the mix is properly stored and maintained. The program should include regular inspections of the storage equipment, temperature monitoring, and proper ventilation. By implementing a quality control program, any issues can be identified and corrected before they compromise the quality of the mix.
Prevent Moisture Contamination
Moisture contamination can cause significant damage to asphalt mix, leading to a decrease in quality and longevity. To prevent moisture contamination, storage equipment should be properly sealed, and any cracks or leaks should be repaired immediately. Additionally, storage should be located in a dry and well-ventilated area to prevent condensation.
Use Proper Handling and Transportation Practices
Proper handling and transportation practices are essential to maintaining the quality of the asphalt mix. Mix should be handled and transported in clean and dry equipment to prevent contamination. Additionally, equipment should be properly cleaned and maintained to prevent cross-contamination.
By following these best practices for asphalt mix storage, you can ensure the quality and longevity of your mix, leading to more efficient and cost-effective asphalt paving.
