Description :
Aqueous soil stabilizers improve soil properties. Water-stability of soil aggregates was determined using 2 different soil stabilizers : S-type and E-type. Various concentrations of the 2 soil stabilizers were tested in soil aggregates (5-10 mm). Testing the aggregates using the static water-measure method showed that the water-satbility index, K, increased with the concentration of soil stabilizers. Two aggregate collapse models were found and discussed. Their pattern depends on the formation of a membrane structure on the surface of the aggregates through physicochemical bonding.
