AASHTO T 269-14 (2018) PDF Download

AASHTO T 269-14 (2018) is a standard that outlines the procedure for determining the percentage of air voids in asphalt mixtures. The purpose of this test is to assess the quality of the compacted asphalt and ensure that it meets the required specifications.

The standard is based on ASTM D3203/D 3203M-2011, although there may be some variations between the two. It is important to note that AASHTO T 269-14 (2018) is specifically tailored to the needs and requirements of the transportation industry.

The test involves compacting the asphalt mixture to a specified density using a gyratory compactor or a similar device. The compacted sample is then measured to determine its volume and mass. The percentage of air voids is calculated by comparing the theoretical compacted volume of the sample with its measured volume, taking into account the mass of the sample.

By quantifying the percentage of air voids, this standard provides a reliable method for evaluating the performance and durability of asphalt mixtures. It is an essential tool for ensuring the quality and longevity of asphalt pavements.
