Abstract
Si ottengono mescole bituminose aventi migliorate proprietà meccaniche aggiungendo ad un bitume un acido polifosforico (I) contenente fosforo, calcolato come P2O5, in quantità da 80% a 87% in peso, e una composizione polimerica (II) comprendente un omopolimero o copolimero del propilene, una frazione copolimerica insolubile in xilene a temperatura ambiente e una frazione copolimerica solubile in xilene a temperatura ambiente, l'acido polifosforico (I) essendo aggiunto in quantità da 1% a 5% in peso rispetto al bitume e la composizione polimerica (II) essendo aggiunta in quantità da 1% a 15% in peso rispetto alla somma del bitume e dell'acido polifosforico (I).
