路面反射裂缝

The Pavetest Overlay 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 susceptibility of Asphalt Mixtures to cracking. Applies tension in a cyclic triangular waveform to a constant  displacement of 0.6 mm (0.026). The sliding block reaches the displacement and then returns to its initial position in 10 sec. (one cycle). The unit is underpinned by Pavetest’s CDASdigital controller, TestLab software and a full complement of accessories hardware and software in unison.

B215EM 电机控制沥青罩面层测试系统 (Overlay Tester)

Technical Feature

• 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.

Standard

• ASTM WK 26816 Standard Test Method for Determining the Susceptibility of Asphalt Mixtures to Cracking Using 

• The Overlay TesterTxDOT Tex-2 48-F –Test Procedure for Overlay Test


Feature

• Compact, fully self-contained, engineered unit

• Electro-mechanical actuator (silentoperation)
• Suitable for ASTM WK 26816 | TxDOT Tex-248-Ftesting protocols
• Applies tension in a cyclic triangular waveformto a constant displacement of 0.6 mm(0.026). The sliding block reaches the displacement and then returns to its initial positionin 10 sec. (one cycle)
• Two piece climatic chamber
• Operator can monitor, set and “Auto tune” thetemperature controller via the PC
