This instrument is based on the industry standards of the People's Republic of China JTJ 052-2000《 In the test procedures for asphalt and asphalt mixtures for highway engineering T 0722-1993 《 The requirements stipulated in the asphalt content test in asphalt mixture (centrifugal separation method)" to increase the centrifugal separation speed and use computer control technology to design and manufacture automated asphalt extraction instruments.
  This instrument automatically extracts the asphalt components in the asphalt mixture, quickly determines the oil-stone ratio of the asphalt mixture, and performs preliminary screening of the aggregate. It is an ideal asphalt content instrument for various road pavement construction enterprises, testing units, relevant scientific research departments, and colleges.

1. Main technical characteristics
 1.This instrument has a floor-standing structure and is a fully automatic and intelligent asphalt content testing instrument for asphalt mixture.
 2.This instrument adopts microprocessor technology, human-computer dialogue mode, parameter settings, operating status, and data display are displayed by the LCD screen at noon, which is intuitive and convenient.
 3.This instrument integrates asphalt extraction and solvent recovery functions, and is closed-circuit recycling of solvents, which has little environmental pollution. Its unique "high-speed-low-high-speed" extraction speed configuration makes the collection of fine ore powder safer and the test results are more reliable.
