SWELLING OF THE SOIL DUE TO THE PRESENCE OF SODIUM SULPHATE AND, IN GENERAL, OTHER SOLUBLE SALTS

HICHAMIENTO DE LOS SUELOS POR LA PRESENCIA DE SULFATO SODICO Y OTRAS SALES SOLUBLES EN GENERAL

USING PREVIOUS RESULTS, THE AUTHOR ATTEMPTS TO EXPLAIN THE MECHANISM OF SWELLING. THE THEORETICAL EXPLANATION IS THAT THE STRESS CAUSING THE EXPANSION IS ONLY THAT OCCURRING IN THE PROCESS OF CRYSTALLISATION; LABORATORY TESTS HAVE SHOWN THAT THE PROCESSES INVOLVED ARE IN AGREEMENT WITH THEORETICAL ASSUMPTIONS. THE INFLUENCE OF THE PROPORTION OF SALT, OF THE SIZE OF THE PARTICLES, AND OF THE SPACE BETWEEN PARTICLES IS STUDIED IN THIS PAPER. THE SMALL INFLUENCE OF THE VOIDS RATIO IS ALSO EXAMINED. THE CONCLUSIONS DRAWN FROM THIS STUDY CAN BE USEFUL IN THE INTERPRETATION OF CASES OF FROST UNDER ASPHALT PAVEMENTS.
