AASHTO T232
Full Name
AASHTO T232 – Standard Method of Test for Determination of Lime Content in Lime-Treated Soils by Titration
Scope
A method of test is described for determining the percentage of lime in soils or aggregates that have been treated with hydrated lime. It is based on the continuous neutralization of an aqueous solution from the lime-treated specimen for a specified time period.
This is accomplished by adding sufficient acid to just neutralize the lime that is continuously being dissolved during the test. The amount of acid used is directly proportional to the lime content of the specimen.
