AASHTO T 135-13 (2017) PDF Download

The AASHTO T 135-13 (2017) standard provides guidelines for conducting tests to determine the soil-cement losses, moisture changes, and volume changes of hardened soil-cement specimens subjected to repeated wetting and drying.

The testing procedure involves compacting the soil-cement mixtures in a mold to achieve maximum density at the optimum moisture content. This compaction process is carried out using the method described in the AASHTO T 134 standard. Once the specimens are compacted, they are subjected to cycles of wetting and drying.

The purpose of this test is to evaluate the durability and performance of soil-cement mixtures under wetting and drying conditions. By measuring the soil-cement losses, moisture changes, and volume changes of the specimens, this standard provides a means to assess the potential effects of repeated wetting and drying on the properties of the soil-cement mixture.
