This rheometer offers greater ease of use and better performance within a compact integrated unit. Because it is designed for asphalt and is only sold into the asphalt industry, the rheometer is optimised specifically for asphalt. This means that it out-performs general-purpose or adapted rheometers in terms of accuracy, throughput and ease of use.
Sample Throughput
Every feature of the design has been implemented with the goal of minimising the time required to make each measurement. This includes loading the sample through to reaching thermal equilibrium, collecting the data and finally cleaning the unit.
Temperature Control
To fully optimise temperature control, this rheometer incorporates a clean and easy to use the system which completely immerses the sample in a temperature-controlled liquid (patented). For testing bituminous materials, this design out-performs all other types of temperature control including forced gas convection ovens and radiatively heated plates.
Gap Setting
The gap can easily be changed to any desired value. For simplicity, both of the specification testing positions are clearly marked and can be easily selected. With most rheometer systems, the gap must be constantly reset during a day's testing and must be readjusted every time the temperature or the measuring systems are changed.
Air Bearing Type
This unit incorporates an air bearing. It requires a supply of compressed air and is warranted to withstand even the most adverse industrial laboratory environments.
Software
Easy to use, Windows driven software is standard for AASHTO specification and grade determination testing is supplied with the PC, BM522.
