BITUMINOUS STABILIZATION /IN PORTUGUESE/

THE SUCTION POTENTIAL IN PLASTIC SOILS IS A DIRECT FUNCTION OF OSMOTIC PHENOMENA. THE DIFFERENCES BETWEEN SOIL CEMENT AND SOIL ASPHALT ARE (1) SOIL CEMENT DEMANDS HUMID CURING AND (2) THE BITUMINOUS STABILIZATION DEMANDS DRYING. THE RECOMMENDED TESTS FOR STUDYING BITUMINOUS STABILIZATION ARE THE CBR TESTS, THE BPCR TEST AND THE CONE PENETRATION TESTS. SEVERAL SPECIFIC METHODS ARE DESCRIBED, SUCH AS: SANDY SOILS CAN BE TREATED BY THE ENGLISH METHOD, "WEST SAND MIX", AND THE SOIL AND SAND MIXTURES ARE STABILIZED BY THE ANIONIC EMULSION OF LOW RUPTURE FOLLOWING THE ARGENTINE METHOD. WATER EMULSIONS EVAPORATE MORE RAPIDLY THAN THE SOLVENT OF CUT-BACK EVEN IF RAPID CURING IS EMPHASIZED. EXPERIENCE SHOWS THAT FINE SANDS (E.G. FROM HYDRAULIC FILLS OR DUNE SANDS) MAY BE EASILY STABILIZED BY IMPREGNATION WITH AN EMULSION OF DILUTED HARD ASPHALT (50/60). /RRI/
