The asphalt dynamic viscosity tester is composed of constant temperature bath, heating tube, stirring motor vacuum decompression system, etc.
Three vacuum capillaries can be placed at the same time.Digital display temperature control instrument, automatic temperature control, accurate measurement, and error correction function.
The shell is sprayed, beautiful and generous.
The heating device is a disk heating tube, and the convection is stirred by the motor to make the heating even.
There is a light under the water bath for outdoor observation.
The vacuum pressure can be set, is displayed by the LED, and the constant pressure is automatically controlled.
The whole test is easy to operate.

The dynamic viscosity of asphalt (60ºC) is a kind of working viscosity of the material in the most unfavorable period of high temperature in summer, and the higher the viscosity, the better the stability. Asphalt with high viscosity produces small shear deformation under load, good elastic recovery performance and small residual permanent plastic deformation, which reflects the enhanced resistance to rutting on the road surface.
The increase of asphalt viscosity is very beneficial to improve the adhesion between aggregates and asphalt. On the one hand, the high viscosity means that the asphalt has a large molecular weight, high content of asphaltene and gum, so that the content of asphaltenic acid and asphaltenic anhydride can produce a better adsorption effect with aggregates. On the other hand, the asphalt film formed by the action of asphalt with high viscosity and aggregate is thicker and the strength of asphalt film is also larger. The ability to resist water damage and traffic load is also strong, so the viscosity of the asphalt is large and the adhesion is good.
