With abundant experience, we warmly welcome you to buy customized dynamic shear rheometer dsr made in China here from our factory. Quality products and reasonable price are available.
Description of Product
The equipment measures the dynamic shear modulus G* and phase angle δ of bitumen across a temperature spectrum of 5-85℃. From these measurements, it determines the viscous and elastic characteristics of both aged and unaged asphalt samples, enabling accurate prediction of their performance against rutting and fatigue cracking.
APPLICATION
Asphalt, coatings, food, cosmetics, polymers, adhesives, medicine, composite materials, etc.
CONFIGURATION
Host, temperature control (circlation) system, asphalt fixture (8/25mm), asphalt test software.
