Application:
According to the industry standard (SY/T5462), a testing system for fully automatic drilling of formation rock samples using micro drills. The drilling pressure of this system is provided by servo air pressure control, through servo air pressure Control,
Thus obtaining stability and The drilling pressure.
The high-precision variable speed is achieved by computer-controlled servo motors, and the time corresponding to the real-time drilling depth is measured using high-precision depth displacement sensors. Relevant parameters are recorded during the testing process,
After the test is completed, process the relevant parameters recorded and provide the drillability level value, drillability category, and drillability level of the experimental rock

FAQs
Which international standards and asphalt grading protocols does this Automatic DSR comply with?
The instrument fully complies with global Superpave and asphalt binder testing standards: AASHTO T 315 / ASTM D7175: Standard Test Method for Determining the Rheological Properties of Asphalt Binder Using a Dynamic Shear Rheometer. AASHTO M 320 / AASHTO M 332: Performance Graded (PG) Asphalt Binder Specifications (including MSCR - Multiple Stress Creep Recovery testing). EN 14770: Bitumen and bituminous binders - Determination of complex shear modulus (G) and phase angle (delta). ASTM D7405: Sta
Can this DSR perform MSCR (Multiple Stress Creep Recovery) testing automatically?
Yes. The software includes pre-programmed AASHTO T 350 / ASTM D7405 / AASHTO M 332 templates for MSCR testing. Automated Stress Cycling: Automatically executes 1-second creep / 9-second recovery cycles at 0.1kPa and 3.2 kPa stress levels. Instant Parameter Calculation: Automatically calculates non-recoverable creep compliance (Jnr), percent recovery (R), and traffic loading classification (S, H, V, E grades) without manual spreadsheet editing.
How easy is the software to operate for routine laboratory technicians?
One-Click Test Wizards: Features pre-configured standard test routines (Superpave PG High Temperature, PG Intermediate Temperature, MSCR, Temperature Sweep, Frequency Sweep, and Time Sweep). Real-time Graphics: Displays live curves of Complex Shear Modulus (G*), Phase Angle (delta), G*/sin (rutting parameter), and G (fatigue parameter). Automated Quality Pass/Fail Reports: Automatically evaluates whether the tested sample meets target PG specifications and exports standardized PDF, Excel, and CS
