The Asphalt Multiple Stress Creep and Recovery Tester (MSCR Tester) is a high-precision rheological testing instrument used to evaluate the high-temperature performance and rutting resistance of asphalt binders. It is widely used in highway engineering, airport runways, research institutes, and asphalt material quality testing.

Asphalt MSCR Tester Multiple Stress Creep and Recovery

Model:TD628-1

I. Standards Met:

JTG E20-2011 T0628, ASTM P246, AASHTO T315-09

II. Application Industries:

Asphalt, coatings, food, cosmetics, polymers, adhesives, pharmaceuticals, composite materials, etc.

III. Main Applications:

Used to study the rheological properties of asphalt, such as conducting SHRP (Strategic Highway Research Program) grading measurements, multi-stress creep measurements, strain scanning measurements, and viscosity measurements. It can be used to measure base asphalt, polymer-modified asphalt, rubber powder-modified asphalt, and aged asphalt after pressure aging and rotary film oven treatment. By measuring the dynamic shear modulus G* and phase angle s of asphalt, it evaluates the viscous (non-recoverable) and elastic (recoverable) properties of aged and unaged asphalt in the temperature range of 5-85℃, predicting its resistance to rutting and fatigue cracking.
