AASHTO T 369-17 Standard of Method of Test for Evaluation of the Low-Temperature Tensile Property of Bituminous Sealants by Direct Tension Test
standard by American Association of State and Highway Transportation Officials, 2017
More info
Full Description
AASHTO T 369-17 applies to hot-poured asphalt crack sealant used in the construction andmaintenance of roadways as specified in MP 25 and PP 85.The test method is used to determine the extendibility and strain energy density (SED) of sealantsat low temperature. It can be used with unaged material or with material aged according to T 367.The test apparatus is designed for testing within the temperature range from -4 to -40C.
This standard covers the determination of extendibility and percent modulus decay in hot-pouredasphalt crack sealant with the use of direct tension testing and by applying the tensile stress-straintest.
