Introduction to the Basic Parameters of the Asphalt Extensometer
2021-10-12
I. Overview and Applications
The asphalt ductility tester is suitable for measuring the ductility of various specifications and models of asphalt, as well as the residue remaining after distillation of liquid asphalt and the evaporative residue from asphalt emulsions. It is widely used in manufacturing, road construction, and research institutions, and is particularly well-suited for testing modified asphalt. The instrument complies with the standards set forth by the Ministry of Transport (JTJ-E52-2011).
II. Characteristics
The liquid crystal low-temperature extensometer conforms to the standards of next-generation high-tech products. It features an external lead screw and linear guide rail positioning, ensuring smooth stretching, high precision, and convenient observation. The stretching drive system employs electronic frequency conversion for stepless speed regulation, featuring low noise and zero running inertia. The control unit is equipped with microcomputer processing, capable of storing 15 sets of data, displaying the moving rate and precise temperature control, and offering a user-friendly operating interface.
