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 performanceelectro-mechanical actuator to provide accurate loading rates up to 50 mm/minute, designed to determine the fracture properties of Asphalt binderin Direct Tension (DTT). The unit is underpinned by Pavetest’s CDAS digital controller, TestLab software and a full complement ofaccessories hardware and software in unison.

沥青直接拉伸试验仪

Technical Features

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

• The system comprises a load frame, with a load cell, integraldisplacement transducer, insulate cabinet, Control and DataAcquisition System (CDAS). The insulated chamber with smallglass door reduces heat loss whilst providing uninterrupted viewof the specimen.

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