A UNITED EFFORT

IPC Global's AMPT was designed to perform, and has been approved for, the three asphalt tests of Projects 9-19 and 9-29 of the National Cooperative Highway Research Program (NCHRP). The AMPT complies with AASHTO TP79 Determining the Dynamic Modulus and Flow Number for Hot Mix Asphalt (HMA).

FULLY INTEGRATED AND ROBUST

IPC Global's innovative thinking has produced the all-in-one compact AMPT. A fully-integrated HMA testing machine incorporating high-performance hydraulic actuator; quiet, built-in, air-cooled hydraulic pump; built-in refrigeration and heating unit; compressed air-driven confining pressure system, integrated triaxial cell; environmental chamber; with its own temperature control unit; and digital control and data acquisition system.

The AMPT is robust and transportable. Its streamlined external controls make it easy to operate. The AMPT is suitable for static laboratories or mobile facilities.

STREAMLINED OPERATION

The most important feature of the AMPT is the specimen testing chamber. For this, IPC Global employs a high specification triaxial cell, which doubles as an environmental chamber.

The crystal clear acrylic triaxial cell allows unimpeded (360 degree) view of the specimen without special lighting. It is raised and lowered by the unit's compressed air system with a two-button safety interlock.

This innovative design eliminates moving a heavy cell assembly when changing test specimens.

The left-mounted triaxial cell provides ample space for a laptop or PC monitor.

THE ULTIMATE IN HMA TESTING TOOLS

The system's software and controller accurately and automatically control the confining pressure. Temperature controlled air, in the integrated pressure vessel, is re-circulated by electric fan and is regulated by an internal heat exchanger. The air temperature is measured half way up the specimen and controlled using a dedicated temperature (PID) controller that provides thermal equilibrium within three minutes of closing the cell.
* Three axial strain transducers, equally spaced around the circumference of the specimen provide strain measurement averaging and eliminate errors caused by non-uniform bending during the dynamic modulus test.
* The clip-on strain transducer mounts and spring-loaded displacement transducers are quick and easy to attach. Epsilon extensometers are available as an option.
* The Swiss-made base connectors make a quick and reliable connection.

IPC Global's innovative AMPT gauge point fixing jig makes it quick and easy to accurately fix gauge points for on-specimen transducers. This eliminates potential errors and saves time.
* A convenient way to glue gauge points to the specimen. Gauge points are positioned on the specimen at the flick of a switch.
* Fixing jig comes with ‘built-in' vacuum generator and handy membrane stretcher

Flow number is related to the resistance of HMA to permanent deformation.
* Repeated load creep tests
* Evaluate rutting
* Accurate simulation of actual loading

Flow time is a quick and simple measurement of the resistance of HMA to permanent deformation.
* Static creep tests
* Measure permanent deformation for rutting evaluation

IPC Global's AMPT is the easiest and most reliable way of performing these tests.
