THE NEXT GENERATION OF MULTI-STATION THERMAL ASPHALT SYSTEM
The Thermal Stress Restrained Specimen Test (TSRST) is used to determine the low temperature cracking susceptibility of asphalt concrete. In the early 1990s the TSRST was developed by Oregon State University (OSU) as part of the Strategic Highway Research Program. The test method became AASHTO TP10.
Main Features
- Up to three working stations (electromechanical and/or servo-hydraulic stations).
- Servo-hydraulic actuator: 30 kN static, 25 kN dynamic, double acting, fatigue rated and equal area type with long life Labyrinth bearings & seals.
- DynafloTM Hydraulic Power Supply: Variable Frequency Drive 2.2 kW pump motor; Silent operation.
- Ability to clone, modify and/or generate user’s own method file(s) to suit their specific requirements.
- Programmable test Wizard to guide the operator step by step based on a recipe book approach.
- Temperature controller programmed via PC software.
The basic MULTI TSRST includes the main frame, the CDAS, the climatic chamber, the refrigeration unit and at least one between the electro-mechanical or servo-hydraulic station. Here below the available configurations:
- B282-10: 1 electromechanical station
- B282-11: 2 electromechanical station
- B282-12: 3 electromechanical station
- B282-13: 1 servo-hydraulic station
- B282-14: 1 electromechanical station / 1 servo-hydraulic station
- B282-15: 2 electromechanical station / 1 servo-hydraulic station
NOTE: Multiple stations configuration (B282-11, B282-12, B282-14, B282-15) allow to run tsrst tests with all stations simultaneously.
In this configurations, utst, rt, tct, utsst and utcst tests are performed on one station at a time. With combined configuration (electromechanical and servo-hydraulic) utcst must be performed with servo-hydraulic station.
