State standards (GOST)
GOST R 58400.8-2019
Automobile roads of general use. Petroleum-based bitumen binders. Method of determining the flexural creep stiffness at subzero temperatures using the bending beam rheometer (BBR)
Included in the scope of accreditation
GOST R 58400.8-2019 applies to petroleum bitumen binders used in the construction, reconstruction and repair of highways, and establishes a method for determining stiffness and creep using a rheometer bending a beam at temperatures from minus 36 ° C to 0 ° C. This method is applicable to bituminous binders with a stiffness in the range from 20 to 1000 MPa.
Key words: bituminous binders, measurement methods, beam, rheometer, bending beam (BBR).
