CONTRIBUTION TO THE PRODUCTION OF DURABLE AND STABLE BITUMINOUS MIXTURES

CONTRIBUTION A LA FORMATION DE MELANGES HYDROCARBONES DURABLES ET STABLES

DETAILS ARE GIVEN OF A MODEL WHICH SHOWS THAT THE MIX-DESIGN OF THE BITUMINOUS MIXTURES USED IN ROAD CONSTRUCTION WITH A VIEW TO ENSURING THEIR DURABILITY AND STABILITY, REQUIRES A CERTAIN KNOWLEDGE OF THE CONSTITUENTS USED. THE MAIN PARAMETERS ARE DISCUSSED. THE DECIDING FACTORS FOR THE INGREDIENTS (STONE, SAND, FILLER, BINDER) ARE THEIR BULK DENSITY, VOIDS SPACE BETWEEN THE AGGREGATES, AND BETWEEN THE COMPACTED SAND GRAINS AND FILLER GRAINS, AND THE QUANTITY OF BINDER REQUIRED FOR THE COATING OF THE STONE AND SAND GRAINS. THE ACCURATE DETERMINATION OF THESE PARAMETERS GIVES RISE STILL IN SOME CASES TO A PROBLEM LINKED TO THE EXPERIMENTAL METHODS USED. EXAMPLES OF MIX-DESIGN FORMULAE ARE GIVEN, AND A COMPARISON IS MADE BETWEEN THEORETICAL AND EXPERIMENTAL RESULTS.
