Technical Parameter Analysis of the Asphalt Extensometer
The asphalt ductility tester features an externally mounted lead screw and linear guide rail positioning, ensuring smooth stretching, high precision, and easy 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 a microcomputer that can store up to 15 sets of data, display the moving speed and precise temperature control, and offers a user-friendly operating interface. This instrument is primarily used to measure 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 applied in manufacturing, road construction, and research institutions, making it particularly suitable for experiments involving modified asphalts.
