AASHTO T 265-15 (2019) PDF Download

The AASHTO T 265-15 (2019) standard is a method used to determine the moisture content of soils in a laboratory setting. The moisture content of soil is an important parameter in geotechnical engineering, as it affects the engineering properties of the soil, including its density, strength, and permeability.

The standard provides guidelines for the proper procedure to follow when conducting the moisture content test. It specifies the equipment needed, such as a drying oven and a balance, as well as the sample preparation requirements. The sample is first weighed and then heated in the drying oven to remove all the moisture. The sample is then reweighed to determine the amount of moisture lost.

This standard ensures that the moisture content of soils is measured accurately and consistently in laboratory settings. It provides a reliable method for engineers and geotechnical professionals to determine the moisture content of soils for various applications, such as designing foundations, analyzing slope stability, and evaluating construction materials.
