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 are tested for strength, toughness, hardness, shape, and water absorption.
Aggregates are also used in the construction of pavement. They help in transferring the loads to the subgrade soil. Different tests on aggregates are conducted to determine desired various properties of aggregates for preparing concrete or mortar and for pavement construction.
As a result, before using aggregates for construction, they must be examined and evaluated for quality. Many types of aggregate studies show that aggregate quality has a significant impact on the quality of concrete and, eventually, the building.
