SH/T 0775-2005 (English Version) PDF

Scope: This test method is suitable for measuring the bending creep stiffness, compliance and m value of asphalt using a bending beam rheometer. The measured flexural creep stiffness range is 20MPa ~ 10MPa (the flexural creep compliance range is 50nPa ~ 10nPa). The measured material can be unaged asphalt or according to GB/T 5304 Petroleum Asphalt Film Oven Test Method, SH/T Aged asphalt obtained by 0736 asphalt rotating film oven test method and SH/T 0774-2005 asphalt accelerated aging test method (PAV method). The test equipment should be able to test samples in the temperature range of -36°C to 0°C. When testing according to this standard, if the deformation of the test piece is greater than 4mm or less than 0.08mm, the test results will be invalid. This standard does not involve safety regulations related to use. It is the responsibility of the user of the standard to develop appropriate safety application procedures before use.
