STABILIZATION OF SAND FOR ROADBASES. SAND DEPOSITS IN FRANCE

TRAITEMENT DES SABLES POUR ASSISES DE CHAUSSEES - LES GISEMENTS DE SABLES EN FRANCE

THE AUTHOR LISTS DEPOSITS OF NATURAL SAND USED IN ROAD CONSTRUCTION EITHER CONVENTIONAL GEOLOGICAL LAYERS, OR RIVER ALLUVIUM, OR, MORE RARELY, BEACHES, DUNES AND CONTINENTAL PLATEAU. MENTION IS MADE OF THE EVOLUTION IN SPECIFICATIONS GOVERNING GRADING, OF THE DEVELOPMENTS IN COMPACTION AND STABILIZATION TECHNIQUES, OF THE RELATION BETWEEN THE GEOLOGICAL SOURCE AND THE GRADING ENVELOPE, AND OF THE POSSIBILITY OF DEFINING GRANULARITY CHARACTERISTICS FROM THE PLANNING STAGE. DETAILS ARE GIVEN OF THE MINERALOGICAL AND PETROGRAPHIC COMPOSITION OF SANDS. A STUDY IS CONDUCTED OF THE RELATION BETWEEN SAND COMPOSITION AND THE FROST SUSCEPTIBILITY OF THE PAVEMENT LAYERS, OF BRITTLENESS DURING COMPACTION, LATER EVOLUTION IN THE PRESENCE OF WATER, ADHESION BETWEEN BINDER AND COATED GRAINS AS A FUNCTION OF THE SHAPE AND DIMENSION OF THE GRAINS. A TYPICAL APPLICATION IS QUOTED: THAT OF THE SAND FROM THE RHINE AND ITS TRIBUTARIES. MENTION IS MADE OF NEW TESTS AND RESEARCH ON IDENTIFICATION TESTS, OF THE 5000 SEDIGRAPH (A DEVICE WHICH AUTOMATES CONVENTIONAL METHODS OF GRADING ANALYSIS). A TABLE SHOWS THE PROVISIONAL CLASSIFICATION OF NATURAL SANDS FOR PAVEMENT LAYER STABILIZATION. FOR THE COVERING ABSTRACT, SEE IRRD ABSTRACT NO 107014.
