Details are given of a test procedure for determining absorption limits of soils. The procedure was developed to evaluate the aptitude for petrifaction (through drying) in some lateritic soils, and soil petrification in situ. The procedure may be applied to both disturbed and undisturbed soil samples. The test procedure was developed for determining the moisture content absorbed by capillarity by pats prepared following a method similar to that used in the determination of the shrinkage limit (Wsub S). This moisture content was called absorbtion limit (Wsub A) and the concepts of petrifaction degree (Wsub S/Wsub A) and absorption degree (Wsub A/Wsub S) were introduced. The former measures the soil aptitude for petrification through drying and when it is equal to the unity the pat is considered entirely petrified since it will only absorb an amount of water equal to its volume of voids.
