Aggregate or Chippings Broad terms for coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete. Aggregates are a component of composite materials such as concrete and asphaltic concrete; the aggregate serves as reinforcement to add strength to the overall composite material. For chip ...

· Aggregate plays an important role in pavement construction. Aggregates influence, to a great extent, the load transfer capability of pavements. Hence it is essential that they should be thoroughly tested before using for construction. Not only that aggregates should be strong and durable, they should also possess proper shape and size to make the pavement act monolithically. Aggregates .
To facilitate medium and low traffic, a bituminous concrete grade of nominal maximum aggregate size mm was necessary to considered for the construction of smooth and impermeable pavement in urban areas. To facilitate thin asphalt lifts, bituminous concrete grading3 is more suitable than grade2. The bituminous concrete grade2 of NMAS has been efficiently used in the highway ...
· Types of Pavement. The following are two major pavement types used in road construction,. Flexible pavement; Rigid Pavement. Flexible pavements, vehicular stress is transferred to subgrade through gain to gain contact of the aggregate through the granular structure. These types of road have less flexural strength, acts like a flexible sheet ( bituminous road).
Aggregate. Aggregate" is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete).

· Aggregates form the major portion of the pavement structure. Bear stresses occurring on the roads and have to resist wear due to abrasive action of traffic. Aggregates are also used in flexible as well as in rigid pavements. Therefore, the properties of aggregates are of considerable importance to highway.
