Table 1 Effects of the application of different improved materials on water-stable aggregate stability indexes. GMD, geometric mean diameter; MWD, mean weight diameter; E_LT, unstable aggregate index; D, fractal dimension. Different lowercase letters represent significant differences among different improved material treatments in the same aggregate stability index.
