Description of the Technology

Within multiple stress creep recovery (MSCR) test, conducted using DSR ( Anton Paar RheoCompass™), bitumen or bituminous binder is loaded (1s) and sequently unloaded (9s) during 60 periodically repeating cycles, initially up to 0.1 kPa and then up to 3.2 kPa, in accordance with AASHTO T 350-14. During the MSCR test two main parameters are determined: percent elastic recovery and nonrecoverable creep compliance.


Non-recoverable creep compliance and percent elastic recovery are two major parameters obtained from the MSCR test.


Multiple stress creep recovery (MSCR) test is used to assess performance of bituminous binders in accordance to Superpave grading system.
