STABILIZATION WITH BITUMINOUS BINDERS. GRAVEL-EMULSION MIXTURES

ESTABILIZACIONES CON LIGANTES BITUMINOSOS. GRAVA-EMULSION

THE PROBLEM OF PROPORTIONING IN SOIL STABILIZATION WITH A GRAVEL-EMULSION AND OF ESTIMATING THE QUANTITY OF LIQUID IS STUDIED. USING TEST RESULTS, THE STABILITY OF ANIONIC AND CATIONIC GRAVEL-EMULSIONS IS COMPARED TOGETHER WITH THEIR BEHAVIOUR DURING IMMERSION-COMPRESSION TESTS AND TESTS ON THE SENSITIVITY TO STEAM. TESTS WERE CONDUCTED ON BITUMINOUS MIXTURES CONTAINING SILICEOUS AGGREGATES AND ANIONIC EMULSIONS BY REPLACING THE LIMESTONE AGGREGATE FRACTION: THE BEHAVIOUR WAS THE SAME AS THAT OF A MIXTURE CONTAINING LIMESTONE AGGREGATES ONLY. RECOMMENDATIONS ARE PUT FORWARD ON THE WATER CONTENT AND COMPACTION. THE FIELDS OF APPLICATION ARE STRENGTHENING, WIDENING, AND STABILIZED SHOULDERS OF SECONDARY ROADS.
