Tests on Aggregate 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. In order to decide the suitability of the aggregate for use in pavement construction, following tests are carried out: Crushing test Abrasion test Impact test Soundness test Shape test Specific gravity and water absorption test Bitumen adhesion test 1. Crushing Test Fig-1 Crushing Test Setup One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS: 2386 part-IV and used to determine the crushing strength of aggregates. Th...
