STABILIZATION OF SAND FOR ROADBASES. STABILIZATION OF SAND WITH BITUMINOUS BINDERS. GENERAL PROBLEMS

TRAITEMENT DES SABLES POUR ASSISES DE CHAUSSEES - TRAITEMENT DES SABLES AUX LIANTS HYDROCARBONES - PROBLEMES GENERAUX

THIS REPORT DEALS WITH THE PROBLEMS OF ESTABLISHING FORMULAE WITH A VIEW: (1) TO DEFINING THE PROPERTIES REQUIRED FROM SAND-BITUMEN AND TO DESCRIBING THE MEANS AND TESTS USED IN LABORATORIES TO CHARACTERIZE THESE PROPERTIES; (2) TO COMPARING THE CHARACTERISTICS OF SAND-BITUMEN WITH THOSE OF OTHER BITUMINOUS MIXTURES; (3) TO DESCRIBING THE DIVERSITY OF THE RESULTS OBTAINED WITH SAND-BITUMEN, INVESTIGATING THE POSSIBILITY OF SIMPLIFYING THEIR CHARACTERIZATION, AND TO GROUPING SAND-BITUMEN CATEGORIES; (4) TO PROPOSING ANALYTICAL METHODS BASED ON TEST ANALYSES. TO IMPROVE THE PERFORMANCE OF SANDS (COMPACTION, STRENGTH, BEHAVIOUR IN THE PRESENCE OF WATER, STIFFNESS, TRACKING, FATIGUE), A NATURAL CORRECTING SAND, CRUSHED OR GROUND FILLERIZED SAND, THE ADDITION OF FINES OR MODIFICATION OF BITUMEN CONTENT CAN BE USED. THE STUDY NEEDS TO BE ALL THE MORE EXHAUSTIVE AS THE MECHANICAL CHARACTERISTICS OF SAND-BITUMEN ARE MORE VARIED THAN THOSE OF BETTER STANDARDIZED BITUMINOUS MIXTURES. FOR THE COVERING ABSTRACT, SEE IRRD ABSTRACT NO 107014.
