The AASHTO T 220-66 (2018) standard is a method used to determine the strength of soil-lime mixtures. Specifically, it focuses on determining the unconfined compressive strength of these mixtures. The standard highlights that a minimum unconfined compressive strength of 690 kPa (100 psi) is satisfactory for the final course of base construction. Additionally, it suggests that materials for such courses should contain a minimum of 50 percent plus 0.425-mm (No. 40) material before treatment. For subbase applications with treated soil materials, the standard recommends a minimum unconfined compressive strength of 345 kPa (50 psi).
