Description / Abstract: This test method applies to bituminous sealants used in the construction and maintenance of roadways.

The test method is used to determine the extensibility and strain energy density (SED) of sealants at low temperature. It can be used with unaged material or with material aged using TP 86. The test apparatus is designed for testing within the temperature range from –4 to –40°C.

This standard covers the determination of extensibility and percent modulus decay in bituminous sealants with the use of direct tension testing and by applying the tensile stress–strain test.
