LS-FT10 Four-Point Bending Beam Fatigue Apparatus
LS-FT10 Four-Point Bending Beam Fatigue Apparatus is a four point bending fatigue tester and SCB asphalt cracking test for AASHTO T321, ASTM D7460, EN 12697-24 workflows. Engineered to meet and strictly exceed the rigorous requirements of AASHTO T321, ASTM D7460, and EN 12697 protocols, this workstation specialized in evaluating both the fatigue life and the complex flexural stiffness modulus of asphalt mixtures under repeated loading. By integrating an advanced 13-channel data acquisition ecosystem with a high-response servo-driven hydraulic station, the LS-FT10 provides the mechanical stability and control fidelity required for testing high-modulus modified binders and stone mastic asphalt. The system transitions laboratory operations from simple PASS/FAIL testing to active health-managed pavement research through intelligent RFID sensor integration, real-time stress-strain logic, and sub-micron resolution in capturing the true neutral-axis strain of the specimen.
13-Channel Elite Control Architecture
Powered by a decentralized 4-axis control system, the LS-FT10 simultaneously manages up to 13 data channels. Utilizing 16-bit AD converters with 8x oversampling algorithms, it eliminates signal noise and ensures absolute fidelity in capturing the dynamic response of complex asphalt mixtures.
Closed-Loop Intelligent Servo-Hydraulics
The system utilizes high-torque servo motor-pump coupling to achieve precise pressure and flow regulation. This technology allows for instantaneous response to specimen stiffness changes, maintaining strict displacement or force control even during rapid modulus degradation.
RFID-Enabled Specimen & Fixture Pairing
Industry-first RFID integration identifies measurement fixtures in real-time. The system automatically syncs calibration coefficients and prevents test execution if fixture parameters do not match the software protocol, drastically reducing human error in high-throughput labs.
Active Thermal Health Management
The hydraulic station is equipped with integrated heating and wind-cooling loops, governed by smart PID logic to maintain oil temperature between 40-60°C. This ensures stable viscosity and system responsiveness across long-duration fatigue tests lasting several days.
Advanced Modulus Degradation Logic
Testing termination is automated through sophisticated algorithms that monitor the product of flexural stiffness and loading cycles (E*N). The system can be programmed to stop at precise 50% stiffness reduction or peak product points for automated life-cycle analysis.
High-Acoustics Isolated Enclosure
Designed for high-stability environmental control, the testing chamber features high-density acoustic insulation and multi-point circulation fans. This setup maintains ±0.5°C uniformity (-20°C to +60°C) while reducing operation noise to sub-65dB levels.
