Description

沥青直接拉伸试验仪

The Pavetest DTT Direct Tension Tester is an electro-mechanical servo-controlled testing machine utilizing digital control of a high performance electro-mechanical actuator to provide accurate loading rates up to 50 mm/minute, designed to determine the fracture properties of Asphalt binder in Direct Tension (DTT). The unit is underpinned by Pavetest's CDAS digital controller, TestLab software and a full complement of accessories hardware and software in unison.

沥青直接拉伸试验仪

Technical Features

• Electro-mechanical unit. The machine applies constant rate of loading to a specimen that is placed in the load frame.

• The system comprises a load frame, with a load cell, integral displacement transducer, insulate cabinet, Control and Data Acquisition System (CDAS). The insulated chamber with small glass door reduces heat loss whilst providing uninterrupted view of the specimen.

• Portable temperature control unit. Operator can monitor, set and “auto tune” the temperature controller via the PC.
