Standard of Method of Test for Evaluation of the Low-Temperature Tensile Property of Bituminous Sealants by Direct Tension Test

SKU124817257 Published by American Association of State Highway and Transportation Officials AASHTO Publication Date2017 Pages CountPages10

The AASHTO T 369-17 (2021) standard is a method of testing the low-temperature tensile property of bituminous sealants using the direct tension test. This standard is specifically applicable to hot-poured asphalt crack sealants used in the construction and maintenance of roadways, as specified in MP 25 and PP 85.

The purpose of this test method is to evaluate the extendibility and strain energy density (SED) of sealants at low temperatures. The test can be conducted using unaged material or material that has been aged according to the procedures outlined in T 367. The temperature range for testing is designed to be from -4 to -40°C.

The standard covers the determination of extendibility and percent modulus decay in hot-poured asphalt crack sealants. This is achieved through the direct tension testing method, which applies tensile stress and measures the resulting strain or deformation of the sealant. By conducting this test, the performance characteristics of the sealant in low-temperature conditions can be assessed, providing valuable information for the selection and evaluation of sealants for road construction and maintenance projects.
