Marshall Instrument

The instrument is subject to the Ministry of Communications "highway engineering and asphalt mixture test specification", which is applicable to Marshall stability test and immersion Marshall stability test, so as to carry out asphalt mixture mix design or asphalt pavement construction quality inspection.

Immersion Marshall stability test (vacuum saturated Marshall test can also be carried out if necessary) is used to test the spalling resistance of asphalt mixture when it is damaged by water. The feasibility of mix proportion design is verified by testing its water stability.

Characteristic：Use force measuring ring dial indicator to display Full digital calibration of pressure and flow.It has the function of preventing wrong operation and over-voltage automatic protection(in case of over-voltage, the instrument will stop pressurizing automatically), and the instrument will not be damaged due to over-voltage.
