Automatic Bitumen Penetrometer Test Set
STANDART: TS EN 1426; ASTM D5; AASHTO T49
LT-AS0035 Automatic Bitumen Penetrometer Test Set
The Automatic Bitumen Penetrometer precisely determines the penetration depth of a standard needle into bitumen and bituminous binders. Its advanced electronic measuring system minimises friction during testing and supports accurate, repeatable penetration measurements.
- Precise needle positioning: Joystick-controlled electric movement allows the penetration needle to approach the sample surface accurately.
- Optical observation support: A magnifying glass and ultra-bright LED lamp provide clear visibility of the needle tip and specimen surface.
- Automatic test cycle: The measuring system automatically resets before each test and controls the penetration procedure.
- Electronic measurement system: The pulse-type measuring system operates independently from the plunger during penetration, reducing friction.
- Programmable test duration: The operator can perform penetration measurements according to the required test period.
- Automatic release and return: The plunger is automatically released and raised again after the selected testing period.
- Digital result display: Penetration results are shown clearly on the digital display.
- Easy calibration: The needle holder can be removed easily for weight calibration.
- Standards compliance: Supports testing according to TS EN 1426, ASTM D5 and AASHTO T49. Liya’s current English page also lists GOST 11501-78.

What Is an Automatic Bitumen Penetrometer?
The Automatic Bitumen Penetrometer determines the consistency of bitumen and bituminous binders by measuring the penetration depth of a standard needle. The system operates under controlled test conditions and helps laboratories evaluate the hardness and consistency of different binder samples.
Penetration values provide important information for asphalt production and bitumen quality control. Automatic operation also helps reduce variations caused by manual testing and supports more repeatable measurements.
Precise Needle Positioning
The instrument uses a joystick-controlled electric movement system to position the penetration needle accurately above the sample surface. This allows the operator to approach the specimen in a controlled manner before starting the test.
A magnifying glass and ultra-bright LED illumination improve visibility around the needle tip. Therefore, the operator can establish the correct starting position more easily. Liya Test lists both the joystick adjustment and optical observation system for the LT-AS0035.
Automatic Test Cycle
Before each test, the electronic measuring system automatically resets. The penetration needle then moves towards the sample using the electric drive.
Once the correct position is established, the plunger is automatically released for the required testing period. At the end of the test, the system raises the plunger automatically and displays the penetration result.
This automated cycle helps maintain consistent operating conditions between consecutive tests.
Electronic Penetration Measurement
The instrument uses a pulse-type electronic measuring system to determine penetration depth. During testing, the measuring system remains separated from the plunger. This design virtually eliminates additional friction that could influence the penetration movement.
The digital display provides a clear reading of the final test result. As a result, laboratories can evaluate and compare different bituminous samples more efficiently.
Easy Calibration and Laboratory Operation
The needle holder can be removed easily when calibration of its weight is required. This design simplifies routine verification and maintenance procedures.
With dimensions of 270 × 480 × 750 mm and a weight of approximately 24 kg, the LT-AS0035 provides a stable laboratory configuration while remaining suitable for benchtop testing.
Penetration Testing According to Standards
The Automatic Bitumen Penetrometer supports penetration testing according to TS EN 1426, ASTM D5 and AASHTO T49. These methods determine the consistency of bituminous materials by measuring standard needle penetration under specified conditions.
Overall, the LT-AS0035 Automatic Bitumen Penetrometer combines precise positioning, automatic test control and electronic measurement in one system. Therefore, asphalt producers, universities and quality control laboratories can perform reliable and repeatable bitumen penetration tests.
