Stand-Alone SCB Testers
EN 12697-44 | ASTM D8044 | AASHTO TP124
The new SCB EmS is a fully automatic stand-alone test system. Utilizing our environmentally friendly Electromechanical Servoactuation (EmS) technology, it quickly determines the cracking resistance of asphalt specimens with accuracy, repeatability and compliance to standards.
79-PV0310: SCB EmS automatic Semi-Circular Bend testing machine.
Complete with PC software. PC and SCB test jigs not included and must be ordered separately. 100-220 V, 50-60 Hz, 1 ph
Silent, compact and highly performing, the SCB EmS is run by our ingenious AutoSCB software. Pre-programmed with testing procedures conforming to international standards, our AutoSCB software will guide you from initial set-up through the full test including the critical slope and energy calculations.
The Semi Circular Bend test determines the cracking resistance properties of a semi-circular asphalt specimen (cut from a Gyratory Compactor sample) with a notch cut parallel to the loading axis. The test is performed at constant vertical displacement until specimen failure. Typically, fracture energy parameters are calculated from the load/vertical displacement graph, to rank the resistance of asphalt mixtures to cracking.
SCB tester EmS is compatible with a range of SCB jigs conforming to the main international standards. ASTM/AASHTO SCB jigs are also compatible with IPC Global dynamic UTMs, AMPTs and AsphaltQubes.
The Semi-Circular Bend Tester features a rigid two-column load frame with easily adjustable crosshead. The cabinet houses the load jack, motorized actuator and digital control system in one compact setup.
34-V1172/SCB: MULTISPEED automatic compression testing machine with digital control and readout unit, motorized ram, two-column structure and adjustable crossbeam. Supplied without load cell (to be ordered separately). Including firmware for automatic performance of Marshall, CBR, Indirect Tensile and Semi-Circular Bend test (to EN 12697-44, ASTM D8044, AASHTP TP124). 220-240 V, 50-60 Hz, 1 Ph
Automatic control of the test speed/travel by the microprocessor controller. Prior to the test, the operator can set travel limits to automatically end the test. The firmware allows calibrating the transducers and setting up to 10 test profiles and saving data onboard. Real-time test graphs and transducer data are displayed on the touchscreen.
The Semi-Circular Bend Tester has built-in data acquisition system with four channels dedicated to two strain gauge load cells and two potentiometric linear transducers; one of each can be used during the test. It is important to note that the processing unit controls the speed in a closed-loop mode, avoiding speed calibrations and tension fluctuation effects.
The user-interface is a large touchscreen graphic display while test data can be stored on a USB pen drive or downloaded through a LAN communication port.
