Asphalt Mix Design Marshall Testing Equipment
The Asphalt Tack Bond Shear Strength Apparatus is a precision instrument designed to measure the shear strength of tack coat material between two asphalt layers. When used in conjunction with a Marshall Stability Test Load Frame, this apparatus provides accurate and reliable results that are essential for quality control in asphalt pavement construction.
Built with a heavy-duty steel frame, this apparatus features both fixed and moveable shear plates. The moveable plate is strategically centered over the shear plane and equipped with roller bearings to minimize drag, ensuring smooth and consistent test results. A calibrated spring controls the lateral load applied to the specimen, while a dial indicator accurately displays the applied force.
Key specifications include a shear plane gap of 0.5 inches (12.5mm) and a maximum shear travel of 0.5 inches (12.5mm). The apparatus comes complete with adapters for testing either 4in (102mm) or 6in (152mm) diameter samples, providing versatility for different testing requirements.
The Asphalt Tack Bond Shear Strength Apparatus is compatible with Gilson Load Frames, as well as most Marshall Load Frames with daylight openings of at least 10in (254mm), making it a versatile addition to any asphalt testing laboratory.
