AASHTO T 288-12 (2016) PDF Download

The AASHTO T 288-12 (2016) standard is used to determine the minimum resistivity of a soil sample in a laboratory setting. The test is primarily used to assess the corrosivity of the soil and determine the conditions under which the corrosion of metals in soil may be intensified.

The standard is divided into two parts. The first part covers the procedures for obtaining and preparing the soil sample for testing. It ensures that the sample is appropriately sized and ready for analysis. The second part outlines the test method itself, describing the steps and techniques for determining the minimum laboratory soil resistivity.

It is important to note that this test method may not accurately assess the corrosion potential of a material if less than 5 percent of the material passes through the No. 10 sieve. This indicates that the test may not be reliable for assessing the corrosivity of such material.
