AASHTO TP 119-15 (2019) PDF Download

AASHTO TP 119-15 (2019) is a standard method of testing the electrical resistivity of a concrete cylinder using a uniaxial resistance test. The purpose of this standard is to determine the resistance of concrete to the penetration of chloride ions by measuring its electrical resistivity. This test method provides a quick and reliable indication of the concrete's resistance to chloride penetration, which is important in assessing its long-term durability.

The test method described in AASHTO TP 119-15 is applicable to different types of concrete where correlations have been established between this test procedure and longer-term chloride ponding procedures, such as those described in ASTM C1556. By measuring the electrical resistivity of a concrete cylinder, this method allows for a rapid assessment of its resistance to chloride penetration without the need for extensive and time-consuming testing procedures.
