Table 2 Correlation between MTD and NE

From: 2D-wavelet based micro and macro texture analysis for asphalt pavement under snow or ice condition

Cutting Plane Condition Equation R2
50% Original MTD = 0.045NE + 0.699 0.7616
Icy MTD = 0.045NE + 0.624 0.7146
snowy MTD = 0.079NE + 0.324 0.9489
100% Original MTD = 0.0003NE + 0.637 0.7153
Icy MTD = 0.0003NE + 0.791 0.5806
snowy MTD = 0.0006NE + 0.633 0.7466
