The deflection of the specimen is measured for this purpose with a resolution of 1µm. The test force is regulated with an accuracy of 1 mN. This makes determination of the flexural strength possible with reproducibility of 1% independent of the operator.
The Bending Beam Rheometer (BBR) has been engineered to perform flexural tests on asphalt binder and similar specimens per ASTM D6648-01 and AASHTO T313-02. Bending Beam Rheometer (BBR3) with Touch-Screen ControlBending Beam Rheometer (BBR3) with Touch-Screen Control Supports the following standards:AASHTO T313, TP87 BS EN 14771 The Bending Beam Rheometer 3 (BBR3) has been designed to perform flexural tests on asphalt binder and similar specimens as part of the PG grading system according to Superpave. Bending Beam Rheometer 2S - Cooper Research TechnologyThe improved Bending Beam Rheometer (CRT-BBR2S) is engineered to perform flexural tests on asphalt binder/ bitumen and similar specimens per ASTM D6648, BS EN 14771, and AASHTO T313. 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.
The Bending Beam Rheometer (BBR) System consists of a uid bath base unit, a three-point bending test apparatus which is easily removed from the base unit for specimen loading and unloading, an external cooling unit with temperature controller, and a calibration hardware kit with carrying case. The system includes a PC and the testing software. Bending Beam Rheometer Test - an overview ScienceDirect The bending beam rheometer (BBR) test applies a static stress to a beam of bitumen and measures the strain rate to derive the stiffness of the beam. The BBR test is conducted on binder that has been subjected to both short-term aging (STA) and LTA/conditioning. Bending beam rheometer testing of asphalt mixtures N2 - This paper provides a test protocol for performing creep tests on asphalt mixture beam specimens using the bending beam rheometer, and addresses the issues related to performing this test. First, a detailed sample preparation procedure is presented and the experimental data are provided to assess the consistency of this method.
The TE-BBR SD is a thermoelectrically-cooled bending beam rheometer for testing flexural creep of asphalt binders from ambient to 40 °C (± 0.03 °C). A crack seal option provides for low temperature characterization of crack seal creep under load for 0.5 thick specimens. The TE-BBR SD meets or exceeds ASTM, AASHTO and SHRP provisions for flexural creep testing of asphalt binders, including Rejuvenator Studies JIVE Asphalt By POETIn order to evaluate rejuvenation of aged asphalt by JIVE, bending beam rheometer (BBR) and dynamic shear rheometer (DSR) tests were carried out on asphalt binder extracted from recycled asphalt pavement (RAP). The asphalt binder was a PG 58-28 from the upper Midwest/Northern tier states. Use of bending beam rheometer test for rheological Oct 20, 2019 · This paper focused on exploiting the potential of the bending beam rheometer (BBR) test for analyzing asphalt emulsion-cement (AEC) mastics tailored for cold in-place recycling applications in the first weeks of curing, i.e. phase which implies the coexistence of viscoelastic and brittle materials.
The improved ATS Bending Beam Rheometer (BBR2S) is engineered to perform flexural tests on asphalt binder/bitumen and similar specimens per ASTM D6648, BS EN 14771, and AASHTO T313. 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.
