AASHTO - T 369
Standard Method of Test for Evaluation of the Low-Temperature Tensile Property of Hot-Poured Asphalt Crack Sealant by Direct Tension Test
|Publication Date:||1 January 2017|
This test method applies to hot-poured asphalt crack sealant used in the construction and maintenance of roadways as specified in M 338 and PP 85.
The test method is used to determine the extendibility and strain energy density (SED) of sealants at low temperature. It can be used with unaged material or with material aged according to R 95. The test apparatus is designed for testing within the temperature range from -4 to -40°C.
This standard covers the determination of extendibility and percent modulus decay in hot-poured asphalt crack sealant with the use of direct tension testing and by applying the tensile stress-strain test.
The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of R 18 are generally considered capable of competent and objective testing/sampling/ins
