HM-59 and HM-73 Bending Beam Rheometers (BBR) by ATS measure the
flexural creep stiffness of asphalt binder from ambient to -40°C to
predict low-temperature thermal cracking of asphalt pavements.
Special molds form small beam samples of binder for testing, and
deflection of the beam is recorded as a constant load is applied.
Load, displacement and bath temperature are displayed in real time
via tabular and graphic forms.
Both models use an air bearing system to assure reliable loading
with accurate and repeatable results. A linear variable
displacement transducer (LVDT) with a range of 6.35mm and accuracy
to ±2µm measures deflection. The stainless steel three-point bend
apparatus is easily removed and reinstalled in the base unit for
convenient sample preparation and loading.
A fluid bath controls temperature of the Ethylene
Glycol/Water/Methanol mixture down to -40°C (-40°F). Process
temperature is controlled by two independent platinum RTD
temperature transducers to maintain stability. Both models fully
comply with ASTM/AASHTO requirements. A source of clean, dry,
compressed air at 50 PSIG minimum must be provided by the user.
Models come with five aluminum specimen Molds with mylar strips, a
Calibration Kit with required weights, and Confidence Beam.
Calibrated test weights and a certified LVDT NIST-traceable
standard are also provided.
HM-59 ATS Bending Beam Rheometer uses a desktop computer with pre-loaded control, acquisition and
analysis software for precise operation. Safe, rapid cooling of the
test fluid is provided by the mechanical refrigeration system.
HM-73 ATS Touch Screen Bending Beam Rheometer retains all of the performance features of the HM-59, but
incorporates a state-of-the-art touch-screen design for easy set up
and operation. The touch-screen controller has walk through menus
for guidance and the machine can be started, stopped and monitored
remotely through an App installed on a smartphone, iPad, or tablet.
The user-friendly control, acquisition and analysis software is
preloaded on the internal computer and allows daily verification
and periodic calibration of load cell, LVDT, and RTD transducers. A
USB port is located on the front of the unit for software upgrades
and data storage. The fluid bath is chilled by a thermoelectric
