LS-TEN-D Direct Tension Test (DTT/DT) System
LS-TEN-D Direct Tension Test (DTT/DT) System is a bending beam rheometer and direct tension tester for asphalt binder testing for ASTM D6723, AASHTO T314 workflows. Applicable to virgin, RTFOT-aged, and PAV-aged binders for low-temperature cracking evaluation.
Fracture Property Workflow for DTT
Measures fracture strain and fracture stress by direct tension in compliance with ASTM D6723 and AASHTO T314 methods.
Integrated Low-Temperature Chamber
One-piece cabinet with dual-layer foamed stainless liner, removable triple-layer insulated transparent cover, and waterproof diffuse lighting for stable low-temperature operation.
High-Throughput Cooling Bath
Large stainless cooling bath with integrated stirrer supports simultaneous conditioning of 7+1 specimen groups for batch testing efficiency.
Precision Motion and Feedback Control
High-subdivision stepper control with closed-loop feedback and imported precision ball-screw tensile stage ensures smooth low-speed displacement control.
Stable Refrigeration and Temperature Control
Optimized single-stage refrigeration architecture with compressor and expansion valve minimizes vibration and improves thermal stability.
Touchscreen + Data Export
7-inch touchscreen interface with real-time test curves and USB export. Optional PC software and USB communication support extended reporting workflows.
