Pavetest Tsrst-Multi:
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 asphaltconcrete. In the early 1990s the TSRST was developed by Oregon State University (OSU) as part of the Strategic Highway ResearchProgram. The test method became AASHTO TP10.
Versatile
Pavetest versatile TSRST-Multi can be used toevaluate:
• Uniaxial tension stress test (UTST)
• Thermal stress restrained specimen test(TSRST)
• Relaxation time, using the relaxation test (RT)
• Tensile creep tests (TCT)
• Unixial cyclic tension stress test (UCTST)
• Unixial thermal stress & strain test (UTSST) it requires additional hardware

First Stand-Alone Servo-Hydraulictsrst on The Market
With up to three servo-hydraulic testingstation in one unit, Pavetest TSRST-Multi isthe stand-alone servo-hydraulic lowtemperature cracking asphalt testing systemon the market able to test up to three differentspecimens simultaneously, under the sametemperature conditions.
Flexible
Designed with flexibility in mind, PavetestTSRST-multi can use different combinationsof servo-hydraulic and/or electro-mechanicaltesting stations with no need for acompressed air supply.
Powerful
Equipped with Pavetest's Controland Data Acquisition System (CDAS) andTestLab software, the user can control up to 3testing stations in one unit, with and ultimate versatility.
Easy to Operate
Pavetest TestLab software makes it easy tooperate the system because it enables theoperator to program the temperature controllerwith ease.
Safe
Pavetest TSRST-Multi employs a reliablerefrigeration system, capable of cooling at arate of 10° per hour. Mechanical refrigerationeliminates the need for liquid nitrogen, offeringa completely safe working environment for theoperator.
Quiet
The Electro-mechanical and/or dynamicallycontrolled hydraulic power supply are almostsilent during testing.
Dynaflo TM
The servo-hydraulic station(s) are powered bythe Dynaflo Hydraulic Power Supply (HPS). TheDynaflo HPS is an innovative concept basedon “inverter” technology: An inverter is usedto control the speed of the pump motor to controlhydraulic oil flow based on the requirements;reducing noise and heat generation, renderingthe HPS silent in most applications. It alsoimproves the longevity of the pump becauseit only works as hard as it needs making it quiet,cool and long lasting.

REFRIGERATION RANGE: -40 °C to + 40 °C, capable of cooling ata rate of 10 °C per hour.
Optional: -50 °C to + 40 °C version.
