Figures & Tables

Figure 1:

Grading curves of RCA specimens tested; image of the parent RCA.

Figure 2:

Schematic drawing of the triaxial base with bender element configuration (after Brignoli et al., 1996).

Figure 3:

Schematic illustration of an S-wave bender element test, displaying generated and received waveforms.

Figure 4:

Example input and received signals in bender element tests; waveform and wavelength ratio at different frequencies for a) the M1 mixture (p′ = 90 kPa) and b) the M4 mixture (p′ = 270 kPa).

Figure 5:

Example Gmax values determined for the M4 mixture versus the wavelength ratio at a) p′ = 90 kPa, b) p′ = 180 kPa, and c) p′ = 270 kPa.

Figure 6:

Example of potential arrival points (the M1 mixture, p′ = 90 kPa).

Figure 7:

Typical plot of small-strain shear modulus (Gmax) against mean effective stress (p′) from the M1 mixture: a) fin = 10.0 kHz, b) fin = 12.5 kHz.

Figure 8:

Small-strain shear modulus (Gmax) for fRCA mixtures based on BE test, peak to peak 2 method: a) fin = 10.0 kHz and b) fin = 12.5 kHz.
