axial, tensile, for asphalt


Epsilon Tech presents 3910 Extensometers. They have been developed to meet testing needs of asphalt core specimen with 4- and 6-inch diameters. The device complies with test method requirements for strain measurement, which were created under the SHRP program of U.S. Federal Highways. The extensometers are suitable for creep compliance as well as testing of tensile strength and dynamic resilient modulus. The extensometers are single integral, bi-axial units. They can measure lateral as well as vertical deformations. They clip quickly onto gage points attached as per test needs. When compared to other types, they provide quicker and simpler mounting. Typically, two units are needed, with each side of the test sample having fixed with one extensometer. Using optional gauge length adapters, they can be changed from 1-inch centers, which are used for 4-inch diameter samples, to the 1.5-inch centers suitable for a 6-inch diameter specimen. The extensometer has magnets at all ends. These magnets quickly snap in position on the steel gage points stuck to the test sample.
