I ran MSCR on different samples with repetitions, I plotted the strain against the time. the graph seems not to move with conventional shapes. all samples display the same anomalies. I check the DSR settings and confirm its correct.
Does anyone know what I am missing?
Also, can you provide and excel example graph?

hope this helps you
Standard practices is - you plot MSCR % Recovery and Jnr at 3.2 kPa. Attached is one of our research reports on MSCR.
thank you dear Zahid Hossain but MSCR test is not available in this research
Sorry for uploading a wrong file. I replaced the attachment with the correct file. Yasir Mohammed Jebur
In Plotting the strain time graph for a specific stress, say 0.1kPa, for a graph of the 10cycles, add the last strain value for each cycle to the strains for the next cycle. You would realise that from the BS EN 16659:2015 standard, the recovered strain at the end of the cycle is equal to the strain before creep for the next cycle. See page 13 of standard.
can you send me the BS EN 16659:2015 standard , please Rufus Adjetey
Basically, you calculate non-recoverable creep compliance and % recovery of binders at the applied stresses (0.1 and 3.2 kPa). Refer to standards AASHTO T350 (test procedure) and M332 (MSCR Standard specifications). Also, check this recent paper on MSCR:
