Results of multiple stress creep and recovery test according to EN 16659 for selected recovered binders.

Binder recovered from	MSCR test results
	Jnr0,1 (kPa^−1)	Jnr3,2 (kPa^−1)	Jnr,diff 3,2−0,1 (%)	R0,1 (%)	R3,2 (%)	Rdiff 3,2−0,1 (%)
Section 1	0.24	0.43	75.77	71.46	54.52	23.71
Section 5	0.32	0.46	42.72	54.96	41.78	23.98
Section 7	0.35	0.58	65.63	35.82	12.18	66.00

J_nr…is the nonrecoverable creep compliance (at two shear stresses: 0.1 kPa and 3.2 kPa) in kPa⁻¹; R is the average percent recovery in %.
