BITUMINOUS CONGLOMERATE LAYER OBTAINED BY USING THE SPENT POWDERS OF EXTINGUISHERS

摘要

A new use is described of spent extinguishing powder as filler in the production of a bituminous conglomerate mixture. Such bituminous conglomerate mixture is used for laying a surface course, or a binder layer, i.e. connection layer between the surface course layer and the base layer. It is proven that the technical-functional characteristics of the spent powder of the extinguishers are the same as or are even superior to those of the traditional fillers in the conventional bituminous mixtures.
