Meet Hot Asphalt Storage Silos

What is hot asphalt storage silo?

It has formed an important part of the asphalt processing chain. Storage silos for hot asphalt are created to keep the temperature of the hot mix of asphalt during its sitting in storage, awaiting truck loading for transport to construction sites. The silos maintain the asphalt at a constant temperature so as not to cool or solidify, thus ensuring that it remains workable and ready for immediate use.

These silos come in an array of sizes and configurations, pertaining to project needs on the asphalt production facility. Most are insulated and equipped with heating systems that maintain asphalt at the desired temperature. The silos also feature designs to minimize segregation of the asphalt mix to assure the material will retain its quality and consistency through the period of storage.

What are Hot Asphalt Storage Silos?

Hot Asphalt Storage Silos refer to silos used in the manufacture of hot asphalt. Such types of silos are designed to keep hot-mix asphalt at elevated temperatures so that asphalt can remain liquid and workable. They are normally manufactured out of steel and are made thermal by some form of insulation on their outer sides. Thus, insulation helps maintain the temperature of the stored asphalt in order to keep it usable until it is consumed for paving activities.

They have several features that enable the silos to store and let out asphalt in the most efficient manner possible. They have a heating element at the top, powered by electricity, natural gas, or other fuels, and this is used in heating asphalt up to the required temperature. At the bottom, they are cone-bottomed, allowing for easy discharge of the asphalt onto trucks. This cone bottom provides the least amount of material segregation, ensuring mix quality consistent as the asphalt is delivered to the site.

Advantages of Hot Asphalt Storage Silos

One of the major benefits accompanying the use of Hot Asphalt Storage Silos is the temperature retention capability relating to asphalt mix. It serves to keep the asphalt workable for an extended period of time, saving waste besides increasing the paving efficiency. This consistent temperature control assists in giving way to quality Asphalt as it prevents cooling down and solidification of the mix prematurely.

Other specific advantages of such silos are an increase in asphalt production flexibility. During the off-season, the asphalt production plants can produce and store large quantities of asphalt in silos and provide it during periods of peak construction. It optimizes the entire production of the plant and minimizes waste of critical time taken for production. Storage of asphalt in silos also eliminates the need for continuous running of the units, therefore making the operation more economic and cost-effective.

How do hot asphalt storage silos work?

All hot asphalt storage silos operate on integral heating systems that keep stored asphalt hot. Generally, the silos are fitted with insulated walls and heating elements that will keep the asphalt within such a temperature range as will prevent solidification. The heating system may be powered by various sources of energy: electricity, natural gas, or oil, depending on the silo design and resource availability around the plant.

Asphalt is charged from the top and stored in the silo until it is ready to be transported. When asphalt is to be transported onto trucks, the material is discharged from the bottom of the silo through the cone-shaped outlet at the bottom. The design of the outlet has been done to ensure smooth and consistent flow of asphalt, minimizing the possibility of segregation. In most of the silos, there are automatic control systems installed that automatically control the temperature as well as flow rate of asphalt to maintain ultimate performance.

Importance of Hot Asphalt Storage Silos during Asphalt Production

Hot Asphalt Storage Silos form an integral part of asphalt production, serving as a buffer between production at a plant and paving at site. This buffer serves the plant with the capability of continuous production independent of the paving schedule. Thus, production could go on in the event of delays in transportation or paving, making the plant more efficient and productive.

More importantly, these silos contribute to the quality of asphalt mix. By maintaining constant temperatures and preventing segregation, the silos ensure asphalt delivered at the construction site meets the specifications required. This goes a long way in ensuring that the pavement achieved is of high quality, hence durable and long-lasting. The capability of storing asphalt in these silos reduces wastage since surplus materials are kept for future use rather than being wasted.
