WebAsphalt binder content affects HMA mixture performance in the areas of stiffness, strength, durability, fatigue life, raveling, rutting and moisture damage. Therefore, it is important in HMA quality assurance, pavement forensic investigations and HMA research. The ignition test is the most common method used to determine HMA asphalt binder content. WebNov 1, 2024 · MSCR test was suggested as a better method to replace rutting factor (G*/sinδ) to evaluate the rheological behavior of modified asphalt binders. Non-recoverable creep compliance (Jnr) and percent recovery (R) from MSCR have been used to characterize the viscoelastic properties under two stress levels, 0.1 and 3.2 kPa. bond and white buildbase
