AASHTO T 283 PDF Free Download
AASHTO T 283 is a standard method of test for resistance of compacted asphalt mixtures to moisture-induced damage. It is used to evaluate the potential of asphalt mixtures to suffer from stripping, which is the loss of adhesion between the binder and the aggregate due to the presence of water. Stripping can lead to rapid deterioration of the pavement and reduce its service life. AASHTO T 283 can also be used to measure the effectiveness of additives, such as anti-stripping agents or hydrated lime, that are added to the asphalt mixture to improve its resistance to moisture damage.

The test method involves preparing and compacting specimens from the asphalt mixture, either in the laboratory or from cores taken from the field. The specimens are then divided into two groups: one group is tested dry, and the other group is subjected to a moisture conditioning process that consists of saturating the specimens with water, freezing them, and then soaking them in warm water. The specimens are then tested for indirect tensile strength by applying a diametral load until failure. The tensile strength ratio (TSR) is calculated by dividing the average tensile strength of the conditioned specimens by the average tensile strength of the dry specimens. A high TSR indicates a good resistance to moisture damage, while a low TSR indicates a susceptibility to stripping.
AASHTO T 283 is an important test for ensuring the durability and performance of asphalt pavements under various environmental conditions. It can help engineers and contractors select appropriate materials and design parameters for their projects. It can also help monitor the quality and consistency of asphalt production and construction.
