Modular Servo Hydraulic Asphalt Tester AST Pro

Project Description

  • Brand new technology ihcluding the new revolutionary E-Mech Servo-electromechanical actuator
  • Easy and versatile with his fully integrated modular system, that includes a 19 kN capacity hydraulic labyrinth actuator
  • Enhanced environmental cabinet that grants a wide temperature range with fast and accurate temperature control
  • Easy-to-use and ergonomic testing system
  • Clarity in results with the Integrated Multi Axis Control System (IMACS)
  • Fully integrated and very compact in design, a perfect solution for both static and mobile testing facilities
  • Optional air compressor that comes integrated in the machine
  • All-in-one touchscreen PC (optional)

E-Mech technology’s main benefits:

  • Improved dynamic performance over servo-pneumatics
  • Stand-alone with no need of compressed air supply
  • Lower maintenance
  • Robust and durable giving a more resilient solution
  • Compact design requiring, in general, a smaller footprint
  • Easy to use
GENERAL DESCRIPTION
The AST Pro belies the power and versatility if this fully integrated modular system. AST Pro is based on the tried and tested technology of the AMPT Pro and its high performance servo-hydraulic labyrinth bearing actuator.

Now you can perform all the most common asphlt test standards in one high performance, compact, modular, easy-to use machine.

AST Pro allows to perform a wide range of tests, including the ones compatible qith AMPT Pro (permanent deformation, cyclic compression, indirect tensile stiffness, indirect tensile fatigue, crack propagation, direct tension-compression, dynamic/complex modulus) plus triaxial compression, four-point and two-point stiffness and fatigue flexural tests.

  • Load capacity: Static 19 kN, Dynamic 17 kN
  • Frequency range: 0.01 to 70 Hz sinusoidal loading
  • Actuator stroke: 30 mm (+/- 15 mm stroke)
  • Actuator type: labirinth bearing
  • Specimen size (dia x H): 100 x 150 nominally, 50 x 135, 38/50 x 110 mm
  • Noise level less than 70 db at 2m
  • Computer control: integrated all-in-one touch screen PC (optional)
  • Air compressor and dryer: low noise, integrated, automated operated-on-demand (optional)
  • Dimensions (H x W x D): 1630 x 1350 x 830 mm with environmental chamber
  • Weight:: 325 kg (including oil)
  • Easy interchangeable load cells

* At temperature probe positioned close to the specimen

Transducers

  • Load cell: low profile pancake type
  • Built-in actuator LVDT: 30 mm stroke
  • Plug-and-Play: up to 8 channels

Services

  • Power without air compressor: 230 V, 50 Hz, single phase, 9 A; 110 V, 60 Hz, single phase, 18 A
  • Power with air compressor: 230 V, 50 Hz, single phase, 11 A; 110 V, 60 Hz, single phase, 22 A
  • Air: Clean dry air at 450-800 kPa; 2 L/sec (optional integrated air compressor available)
  • Hydraulic oli: pre-filled with high specification pre-filtered, ISO 46 Premium Mineral Oil
