When it comes to constructing roads, bridges, buildings, and other major structures, one crucial element that must be taken into account is the foundation. The foundation serves as the base upon which everything else is built, and it must be strong, stable, and able to support the weight of the structure. One material that is commonly used as a base for construction projects is aggregate base.

What is Aggregate Base?

Aggregate base is a type of material that is used as a foundation for construction projects. It is typically made from crushed stone, gravel, or recycled concrete, and it is often compacted to create a solid, level surface upon which the rest of the construction project can be built.

Definition and Types of Aggregate Base

Aggregate base is a granular material that is composed of crushed rock and/or recycled concrete. There are several different types of aggregate base materials, including:

• Class II Aggregate Base
• Class III Aggregate Base
• Road Base
• Cement-Treated Base

Class II Aggregate Base is the most commonly used type of aggregate base in construction projects. It is made from a mixture of crushed stone and stone dust, and it is often used as a base layer for roads, parking lots, and other areas that will be subject to heavy traffic. Class III Aggregate Base is similar to Class II, but it is made from a larger mixture of stone sizes and is typically used in areas with less traffic. Road Base is a type of aggregate base that is specifically designed for use in road construction projects. It is made from a mixture of crushed stone and asphalt, and it is often used as a base layer for roads and highways. Cement-Treated Base is a type of aggregate base that is made by mixing crushed rock with cement. It is often used in areas that need a very strong and stable foundation, such as airports and industrial facilities.

Importance of Aggregate Base in Construction
