Experimental study for the formulation of a fractal principle for the valuation of the mechanical properties of the binder layers and as a basis of a flexible paving (Q2704117)

For the planning of the bituminous mixtures employed for the superficial layers of the road paving, remarkable importance has the choice of the used materials, so that opportune requirements of quality and durability are assured in exercise, guaranteeing to the use fit standards of safety and of comfort of march. In this paper, it has been proposed a particular criterion of analysis of the granular materials, forming the mixtures, that uses fractal geometry. Through a special experimental investigation, then, it has been possible to individualize the relations existing between some typical indicators of the conglomerated bituminous, what the volume mass, porosity and Marshall rigidity and the fractal dimension of the whole of used grains. According to such interpretation, it results, also, operationally possible, after the more suitable physical-mechanical qualities have been settled, according to the particular destination of use of the road mixture, to draw the optimal fractal number and, consequently, to choose an appropriate granulometric assortment.NEWLINENEWLINEFor the entire collection see [Zbl 0955.00040].
