AASHTO T 222-81 (2021) PDF Download

The AASHTO T 222-81 (2021) standard provides guidelines for conducting nonrepetitive static plate load tests on subgrade soils and flexible pavement components. The purpose of this test is to gather data that can be utilized in the evaluation and design of both rigid and flexible-type airport and highway pavements.

The standard outlines the procedures and techniques to be followed when performing the plate load test. It applies to both compacted soils and natural subgrade soils, enabling a comprehensive assessment of the pavement's load-bearing capacity. By conducting static plate load tests in a nonrepetitive manner, engineers can obtain accurate data regarding the response of soil and materials under static loads.

This standard serves as a vital tool in pavement design and evaluation, offering valuable insights into the performance characteristics of airport and highway pavements. By using the data gathered from nonrepetitive static plate load tests, engineers can make informed decisions regarding the design and construction of these pavements, ensuring their durability and ability to withstand traffic loads over time.
