A61 Automatic Asphalt Marshall Stability Tester Marshal Stability compressive Tester
This model is used in Marshall stability test and immersed Marshall stability test to carry out asphalt mixture mix ratio design or asphalt pavement construction quality inspection. Water-immersed Marshall stability test (vacuum-saturated water Marshall test can also be performed as required) for checking the ability of the asphalt mixture to resist spalling when damaged by water. The possibility of designing the mixture ratio by testing its water stability. It is used to determine the thermal stability and resistance to plastic deformation of asphalt mixtures-stability and flow value. Provide accurate basis for the design of asphalt mixture composition. It can realize the measurement of stability and flow value
