In Brasile, il trasporto su strada è il principale mezzo di trasporto e la maggior parte delle strade è pavimentata con calcestruzzo asfaltato come strato di copertura. Lo strato di attrito poroso (PFL) è caratterizzato da una granulometria aperta con una piccola quantità di fini e un’alta percentuale di volume vuoto. Questo studio ha caratterizzato gli aggregati di granito e i leganti per asfalto AMP 55/75 e ha verificato l’idoneità di questi componenti per la produzione di PFA. Le fasi metodologiche della ricerca corrispondevano alla caratterizzazione fisica degli aggregati, alla caratterizzazione reologica del legante e all’analisi del dosaggio dell’asfalto mediante parametri volumetrici e resistenza alla trazione. I dati di questo studio sono risultati coerenti con gli standard adottati in termini di caratterizzazione degli aggregati e di ottenimento dei volumi dei vuoti, dello slump e del run-off. I valori ottenuti per la resistenza a trazione non hanno rispettato lo standard stabilito. Un suggerimento è quello di effettuare un’analisi microstrutturale dei materiali utilizzati.
