Asphalt Tack Bond Shear Strength Apparatus

Asphalt Tack Bond Shear Strength Apparatus

Supports the following standards: AASHTO T114

The Asphalt Tack Bond Shear Strength Apparatus is used in a Marshall Stability Test Load Frame to measure shear strength of tack coat material between two asphalt layers. The heavy steel frame holds fixed and moveable shear plates. The moveable plate is centered over the shear plane and features roller bearings to minimize drag. 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.
