Table 3

Test condition adopted for 4PBB test.

S. number	Test parameter	Test condition
1	Test temperature (°C)	20 ± 0.5
2	Strain amplitude (10^−6 m)	200–1000
3	Loading frequency (Hz)	10
4	Air void content (%)	4 ± 0.2
5	Type of loading	Sinusoidal
6	Failure condition	When the flexural stiffness is reduced to 50% of the initial flexural stiffness or 200000 loading cycles have been applied, whichever occurs first.
