Demulsification velocity tester for emulsified asphalt

The utility model relates to a demulsification velocity tester for emulsified asphalt. The tester comprises a power supply, a voltmeter, an ampere meter, a rod electrode, a disk electrode and a computer, wherein one end of the power supply is connected with the rod electrode, and the other end of the power supply is connected with the disk electrode through the ampere meter; the ampere meter is connected with a display through the computer. The demulsification velocity of the emulsified asphalt is represented by detecting the magnitude of current flowing through the circuit, so as to really reflect the reflection condition when light irradiates a pavement. Thus, the demulsification velocity tester is high in simulation degree, good in practicability and easy to implement.
