Prediction of Small-Strain Dynamic Properties on Granulated Spherical Glass Bead-Polyurethane Mixtures

Table 2

Composition ratio of mixtures.

	Small material	Large particles
	PB	GB 100	GB 250	GB 400	GB 600	GB 700
Particle-size ratio (^1)	—	1.1	1.6	2.9	4.2	6.3
Polyurethane bead contents (PC (%))	—	0	0	0	0	0
	—	1.17	1.17	1.17	1.17	1.17
	—	2.32	2.32	2.32	2.32	2.32
	—	11.01	11.01	11.01	11.01	11.01

¹Particle-size ratio that is defined as the ratio of median grain size of GB to the median grain size of PB.
