Hasábhajlító reométer (BBR) - Bending Beam Rheometer

Szabvány megfelelősség: EN 14771A, STM D6648, AASHTO T313  


Hasábhajlító reométer (BBR) - Bending Beam Rheometer

Bending Beam Rheometer is engineered to perform flexural tests on asphalt binder and similar specimens. These tests consist of a constant force being applied to a specimen in a chilled bath in order to derive specific rates of deformation at various temperatures.

TEST FRAME:
 - Three-point bend test apparatus
 - Integral stainless steel frictionless construction
 - Load cell 500 g with mechanical overload protection
 - Linear Variable Displacement Transducer (LVDT) 0.25 in (6,35 mm)
 - Two independent platinum RTD for precise temperature control
 - Liquid bath:
 stainless steel construction
 temperature range: -40 to 25°C
 mechanical refrigeration system
 cooling coil located within the test bath
 no pumping required. Cools Ethylene Glycol - water - methanol
 mix (recommended for safety) to -40°C.
 - Compressed air: 0.34 MPa clean, dry air supply required
 - CE certified model

SOFTWARE:
 - Control, acquisition and analysis software
 - BBR Software version 4.16W
 - Computer interface card
 - Menu driven program, mouse compatible
 - Daily calibration routines
 - Displays and graphs real time load, displacement and bath temperature

The BBR System includes: complete calibration kit with carrying case, 5 specimen molds with accessories, PC, accessories.
 Power supply: 230V 1ph 50/60Hz
 Weight: 110 kg approx.
