After stabilization with a hydrophobic additives, important parameters are determined:
– soaking coefficient S
– resistance to capillary water absorption coefficient R
– elastic modulus (Young’s modulus) E
Material tests typical for hydraulic binder stabilization (eg compressive strength) may be performed, however they are not required for hydrophobic stabilization. The evaluation of the values obtained from the tests must take into account that these are two different soil stabilization types, for which individual results of the same tests may have different meanings for the quality.
