SPT (Simple
Performance Tester)
The
IPC Simple Performance Tester (SPT) is a fully integrated package comprising
a triaxial cell, environmental chamber, hydraulic actuator and pump, a
refrigeration and heating unit with heat exchanger and a control and data
acquisition system. The triaxial test cell is mounted on the top left of the
unit. There is space for the |

5 kN, 10kN and 14 kN Universal Testing Machines
(UTM-5P, UTM-10P and UTM-14P) The UTM-5P (Universal Testing Machine 5 kN, Pneumatic)
is the smallest and most popular of our series of Universal Testing
Machines. By coupling recent developments in pneumatic control valves
with digital control technology, we have produced a new testing machine
that equals and even exceeds the performance of many electro-hydraulic
testing machines; but at a fraction of their price. The UTM-10P and UTM-14P
are virtually
the same machine fitted with a 10kN and 14 kN pneumatic actuator and a
larger capacity load cell. |

Beam Fatigue Apparatus The Beam Fatigue Apparatus is a stand-alone system for four-point fatigue life testing of asphalt beams subjected to repeated flexural bending. The cradle mechanism allows for free translation and rotation of the clamps and. Pneumatic actuators at either end of the cradle center the beam laterally and clamp it. Servo-motor driven clamps secure the beam at four points with a pre-determined clamping force. Haversine loading is applied to the beam via the built-in digital servo-controlled pneumatic actuator. The innovative "floating" on-specimen transducer measures and controls the true beam deflection irrespective of loading frame compliance. Software has been developed to automatically perform the various standards including: EN12697-24 Annex D*, EN12697-26 Annex B*, prEN13108-20 Annex D*, AASHTO T321, AST 03. * At frequencies up to 20Hz. The latest Windows-based software allows for both controlled strain and controlled stress loading. For a better resolution picture click on photo |

Beam Fatigue Apparatus
- Jig Only IPC Global has recently developed a Beam Fatigue Test jig for use directly with our UTM load frames. This is particularly pertinent to owners of hydraulic systems where it has not previously been possible to use the same CDAS (Control and Data Acquisition System) as the UTM. This enables the user to utilize the existing CDAS, as well as the load frame, actuator, servo valve, load cell, and displacement transducer of their existing testing system, thus giving a lower cost option than to purchase a stand-alone BFA system

25 kN Universal Testing
Machine (UTM-25) This versatile machine is based on a 25 kN capacity hydraulically-driven load-frame and was designed to meet the needs of laboratories wishing to carry out a range of tests on either bound or unbound pavement construction materials. An integrated control and data acquisition system (CDAS) provides accurate force or displacement waveform generation and control and enables automatic sequencing of test procedures. Windows-based PC software provides a user-friendly interface with the system. A temperature cabinet designed specifically for the UTM-25 provides adequate space for the load frame, a wide range jigs and fixtures for various specimen dimensions, and room to spare for specimen conditioning. To minimise the lab floor-space required heating and cooling is built into the base of the cabinet. Facilities are also provided to introduce liquid nitrogen, where lower temperature operation is required. For a higher resolution picture showing the 25 kN load-frame with hydraulic actuator, mounted in a -15 to +60ºC temperature cabinet, click on photo or |

Rapid Triaxial Testing
Cell (RaTT) Most pavement structural models in use today are, or were developed, with the expectation that triaxial testing data would be used to provide the input for the material properties in the structural model. The triaxial test has been used with notable success in the field of geotechnical engineering for applications such as earthquake and tunnel modeling as well as for pavements. For a better resolution picture click on photo. The IPC triaxial cell uses a larger diameter confining cylinder around the specimen, fitted with an internal rubber membrane that can be inflated to apply confining pressure to the specimen. The system provides automated control of cell movement to simplify specimen handling, and computer control of both confining and axial stress, together with instrumentation for vertical and horizontal strains and temperature. The machine is designed to apply a constant confining pressure and a sinusoidal vertical loading at various frequencies. However, the machine is also capable of controlling the confining pressure at other than constant levels such as would be required for hydrostatic compression testing. Because the apparatus can perform tests at multiple frequencies as well as multiple stress states, it can be used for both QC/QA and mixture design and analysis. This capability enables the machine to quantify not only time-dependent response, but also stress-dependent response of the material, two features that are required for flexible pavement materials characterisation.
