This test method is suitable for determining the penetration of road petroleum asphalt, modified asphalt, and the residue after evaporation of liquid petroleum asphalt or emulsified asphalt.

1. Equipped with a magnifying glass and an illumination lamp for accurate observation of the needle tip alignment with the sample plane. 2. The lifting and lowering bracket can be freely adjusted for convenient needle tip alignment with the sample plane. 3. Equipped with HWY-3 constant temperature water bath to provide circulating constant temperature water to the constant temperature bath on the penetration tester platform, achieving the required temperature environment for the tested sample. 4. Equipped with a penetration display, providing stable and accurate data for convenient observation.

Employing an automated design concept, the test tank is completely free of screws, guide rails, and other devices, making sample installation extremely convenient with a maximum tensile length of 1.5 meters. The constant temperature water bath uses a 304 stainless steel double-layer design, equipped with a circulating water tank and a static water tank. The water temperature in the static water tank is uniform and still. The servo motor ball screw transmission design ensures smooth and synchronized tensile process, uniform speed, absolutely no jitter, and accurate elongation display.

This instrument is a small, desktop-sized unit. It uses a microcomputer for control, linear heating, and automatic stirring, providing accurate and reliable measurement results. Test results are displayed automatically upon completion. The beaker is made of high-temperature resistant glass, and the specifications of the heating rate, steel ball positioning ring, steel balls, etc., meet the requirements of the standard.

Digital display, constant temperature water bath, adjustable needle insertion time control device. A special low-temperature circulating constant temperature water bath provides a pre-settable, constant low-temperature environment for the tested sample.

Water bath experiments can be selected from 5～90℃, or glycerol experiments from 35～+160℃ can be performed; using microcomputer control, automatic stirring, and linear heating, the heating rate maintains a standard of 5℃/min;  

This instrument is a small desktop structure, using microcomputer control, linear heating, and automatic stirring. The measurement results are accurate and reliable, and the test results are automatically displayed on a 5-inch LCD touch screen after the test is completed. The temperature rise per minute is automatically recorded.

The temperature control section uses a high-precision, fast-response, and clear-reading digital electronic temperature controller. The refrigeration unit is an imported 750WF22 high-power compressor. Deep cold can reach minus 28℃.

Used to determine the mass loss of road petroleum asphalt after heating with a rotating thin film. And, as needed, determine the changes in properties such as penetration, viscosity, ductility, and softening point of the asphalt residue after heating the rotating thin film, in order to evaluate the aging performance of the asphalt.

The laboratory is constructed with a double-layered stainless steel door. The observation window is rectangular. The interior is equipped with lighting, a cage fan, forced ventilation ducts, vents, a turntable, and other facilities. The laboratory shell is entirely made of stainless steel.

This instrument uses a high-precision temperature control instrument with a temperature control accuracy of 0.1℃. This instrument features a compact structure, beautiful appearance, dual-microcomputer control, convenient operation, and high measurement accuracy.

DescriptionThis instrument is suitable for determining the dynamic viscosity of viscous petroleum asphalt using a vacuum reduced-pressure capillary viscometer. Unless otherwise specified, the test temperature is 60℃, and the vacuum degree is -40kp ± 0.066 kp. This instrument is also suitable for other substances with a viscosity in the range of 0.0036～20.000Pa.s using the vacuum capillary method, with a test temperature of 60℃ and a vacuum degree of -40kp (300mmHg).

DescriptionThis method is suitable for determining the kinematic viscosity of viscous petroleum asphalt, liquid petroleum asphalt, and their distillation residues using a capillary viscometer.

The level bubble is in front, and you can adjust the level while sitting, which is very convenient.

The product is suitable for measuring the asphalt consumption in asphalt pavement construction to assess construction quality, and is also suitable for measuring the asphalt consumption in asphalt pavement in old road surveys.

Test the tenacity of asphalt under specific conditions to evaluate the modification effect of asphalt after adding modifiers
