Lateral load on the specimen is controlled by a calibrated spring and a dial indicator displays force. The shear plane gap is 0.5″ (12.5mm), and maximum shear travel is also 0.5″ (12.5 mm). Adapters are included for testing either 4″ (102mm) or 6″ (152mm) diameter samples. The Tack Bond Shear Strength Apparatus is compatible Marshall Load Frames with daylight openings of at least 10″ (254mm). The HA-1343 Asphalt Tack Bond Shear Strength Apparatus tests 4″ (102mm) and 6″ (152mm) Marshall samples. The HA-1343M Asphalt Tack Bond Shear Strength Apparatus accommodates testing of 100mm and 150mm Marshall specimens.
- Optimal method for measuring shear strength of tack coat between two layers of asphalt
- Roller bearing minimize drag
- Compatible with most Marshall Load Frames
