Asphalt mix storage is a critical part of any asphalt paving project. Proper storage ensures that the asphalt mix maintains its quality and consistency, which is essential for a successful and long-lasting pavement. In this article, we’ll discuss the different types of asphalt mix storage and best practices to follow.
Types of Asphalt Mix Storage
There are two main types of asphalt mix storage: hot storage and cold storage. Hot storage is used for storing asphalt mixes that are hot, meaning they have not yet cooled down after production. Cold storage, on the other hand, is used for storing asphalt mixes that have already cooled down.
Hot storage is typically used for short-term storage of asphalt mixes, which are usually kept at a temperature of around 300F to 350F. The most common type of hot storage is the silo, which is essentially a large vertical cylinder with a cone-shaped bottom. Silos can range in size from small portable units to massive structures that can store thousands of tons of asphalt mix.
Another type of hot storage is the surge bin, which is essentially a large hopper that is used to temporarily store hot asphalt mix before it is transferred to the paving site. Surge bins are typically used for smaller paving projects or when a silo is not practical due to site constraints.
Cold storage is typically used for long-term storage of asphalt mixes, which are usually kept at a temperature of around 200F to 250F. The most common type of cold storage is the horizontal storage tank, which is essentially a large insulated tank that can store thousands of tons of asphalt mix.
Best Practices for Asphalt Mix Storage
Regardless of the type of storage used, there are several best practices that should be followed to ensure the quality of the asphalt mix is maintained:
Inspect storage units regularly for signs of wear and tear, and perform any necessary maintenance.
Keep storage units clean to prevent contamination of the asphalt mix.
Store the asphalt mix at the appropriate temperature to prevent it from breaking down or becoming too thick.
Use proper ventilation to prevent the build-up of volatile organic compounds (VOCs).
Keep track of the inventory of the asphalt mix to prevent shortages or overages.
By following these best practices, you can ensure that the asphalt mix maintains its quality and consistency, which will result in a successful and long-lasting pavement.
Asphalt mix storage is a critical part of any asphalt paving project. Whether you’re using hot storage or cold storage, it’s essential to follow best practices to ensure the quality and consistency of the asphalt mix. By doing so, you can ensure that your pavement project is a success and will last for years to come.
