- Machine is designed as per ASTM E1942
- Accessories are designed as per asphalt testing standards, ASTM, EN, AS BS, AASHTO
- Operating mechanism: Servo Hydraulic Actuator
- Capable of performing specialized tensile, compression, and bending tests on concrete specimens (static and dynamic)
- Capable of performing specialized tests on asphalt; low capacity load cells can be installed, 20 types of specialized accessories can be attached in order to perform specialized tests on asphalt specimen such as compression tests, investigate dynamic modulus of Hot-Mix asphalt, semi-circular bending test, indirect tensile test, DSCT test, overlay test, Creep testing jig platen, universal triaxial test, and 4-point bend fatigue test
- Temperature chamber with different temperature ranges, capable of controlling the temperature at ambient temperature, 20º
- High accuracy in applying dynamic and controlled loads with various amplitudes: constant force, constant displacement, constant stress, and constant strain according to types of fatigue wave patterns including sinusoidal, square, triangular, saw-tooth, and required form or random points pattern
- Furnace is equipped with PT100 thermocouples, and PLC control system complete with programmable HMI
- Applying fatigue loads with high frequencies at ambient temperature, as well as inside the furnace
- Equipped with separate PID controllers for each controlling mode; defining the accurate wave pattern on the software
- Interface with DSP technology, working frequency 5 KHz, controlling and measuring the force, extension, and strain with 5 KHz frequency response (closed loop)
- Using accurate dynamic low profile load cell to reduce the effects of lateral forces
- Equipped with non-contact digital encoder installed on jack (full stroke)
- A powerful software capable of real time controlling in different experiments, and processing the data
- Moog servo valve, made in USA
- Equipped with inter cooler
Axial fatigue testing machines (SAF series) can perform fatigue and durability tests to determine the service life of various specimens according to different standards including ASTM E1924, ISO 14242, etc. They can apply dynamic loads with four standard patterns with the capability of defining combined patterns, as well as assuming the corresponding wave pattern within the range of force, extension, stress or strain defined up to 50 Hz frequency. State-of-the-art electronic hardware with quick response and high data acquisition rate, good quality transducers, the most accurate servo valves, as well as real time individual controllers are used in this equipment. Real time system and powerful software with optimization algorithms, and data processing for each control mode, as well as special hydraulic/mechanical systems designed for long-term tests enable the fatigue machine to simulate and implement the most real and diverse circumstances for asphalt fatigue test. The fatigue machine is equipped with non-contact digital extensometer installed on the actuator without restriction in stroke, extension resolution 1 µm, measurement accuracy 0.05 mm at full stroke. Double acting actuator with equal level of compression is also intended. Operating mechanism of this equipment is by Hydraulic Servo Valves, offered with various linear speeds and units; DSP hardware with high frequency is used. Quick response, high sampling rate and control system enables the machine to get feedback from measurement instruments per 200 microseconds (closed loop control with respect to PID controller). The fatigue machine is also capable of performing crack tests (crack initiation and crack growth tests). The chamber is designed to carry out test under cold/hot conditions. For hot test, there are heater and blower to increase the temperature up to 80ºC (for long-term test), and for cold test the specimen temperature is lowered to -20ºC to 50ºC. The chamber is equipped with PT100 thermocouples, and a PLC control system with HMI display. Temperature resolution 0.1ºC; range of temperature uniformity inside the chamber does not exceed ±5ºC. The machine has special and advanced software (Intranet connection with the hardware via LAN port) with the capability of applying periodic loads with specified amplitude and frequency but different wave patterns, applying noise, offset, quantity of applied cycles, and determining stored cycles. All test parameters can be changed online, during test and all the required outputs can be reported. The fatigue machine is equipped with water inter cooler system with new plate heat exchanger with high efficiency to dissipate the oil temperature.
