Recommendation of Suitable Loading Waveforms and Wavelength Equations for Dynamic Modulus Based on Measured Wheel Loads

Table 1

Wavelength at different depths.

Depth condition	Wavelength/cm	Correlation coefficient
0 < h < 2.5 cm	D = 21.7	N/A
2.5 cm ≤ HAC ≤ 3.8 cm		0.987
3.8 cm < HAC, and h ≤ 0.5757HAC + 0.0424		0.980
Else		0.987
