Composition and Installation & Use of the Asphalt Extensometer
The asphalt ductility tester mainly consists of a mechanical tensile device, a temperature control unit, and an LCD display section.
1. The mechanical tensile device is driven by a low-speed motor and moves from one end to the other via a transmission system comprising gear racks and gears. The transmission mechanism is also equipped with a variable-speed device, enabling two different tensile speeds to be achieved.

What are the characteristics of a rotary compactor?
The rotary compaction apparatus features a frame made of high-hardness, premium-grade steel, ensuring precise angular control. Pneumatic servo control is achieved via a precision pressure regulator, and a linear displacement sensor measures the height. The rotational motion is generated by a high-precision centrifugal system; simple settings guarantee consistent rotation angles and accuracy.

Introduction to the Operating Instructions for the Asphalt Softening Point Tester
The operating instructions for the asphalt softening point tester are as follows:
Place the metal ring on a glass plate coated with a glycerin-talc powder separator (glycerin : talc powder = 2:1). Heat the asphalt (for petroleum asphalt, heat to ≤ the estimated softening point + 90℃; for coal asphalt, heat to ≤ the estimated softening point + 50℃). Then, pour the heated and thoroughly mixed asphalt into the metal ring, ensuring that the asphalt level slightly exceeds the surface of the ring.

Installation and Operation of the Asphalt Penetration Tester
The asphalt penetration tester is suitable for determining the penetration of residual materials left after evaporation of road petroleum asphalt and liquid petroleum asphalt.
Installation and Debugging Instructions:
1. After unpacking, check whether any damage has occurred during transportation.
2. According to the packing list, verify that all components are present; if any items are missing, promptly notify the seller.
