The present invention is related to asphalt and asphalt-mineral compositions including at least one cationic organosilicon compound selected from a group consisting of. Y3-a Si(R1a)R2NR3R4R5X-, Y3-a Si(R1a)R2P+R3R4R5X-, Y3-a Si(R1a)R2ZX-; or mixtures thereof, wherein in each formula Y is independently selected from a group consisting of OR, O(CH2CH2O)n H, (CH3OCH2CH2O), and (CH3CH2OCH2CH2O); a has a value selected from 0, 1 or 2; n is a value from 1 to 10; R is C1-C4 alkyl; R1 is either methyl or ethyl; R2 is C1-C4 alkylene group; R3, R4 and R5 are each independently selected from a group consisting of C1-C22 alkyl wherein at least one such group has more than 8 C-atoms, -CH2C6H5, -CH2CH2OH, -CH2OH and -(CH2)y NHC(O)R6 wherein y has a value of from 2 to 10 and R6 is a C1-C12 perfluoroalkyl radical; X is chloride, bromide, fluoride, iodide, acetate or tosylate; and Z is pyridinium ring of formula C5H5N+.
La présente invention concerne des compositions d'asphalte et des compositions asphalte-minéral comprenant au moins un composé d'organosilicium cationique choisi parmi Y3-aSi(R1 a)R2N+R3R4R5X-, Y3-aSi(R1 a)R2P+R3R4R5X-, Y3-aSi(R1 a)R2ZX- et les mélanges de ceux-ci. Dans chaque formule, Y est indépendamment choisi parmi OR, O(CH2CH2O)nH, (CH3OCH2CH2O) et (CH3CH2OCH2CH2O) ; a vaut 0, 1 ou 2 ; n prend une valeur entre 1 et 10 ; R représente un radical alkyle en C1-C4 ; R1 est un radical méthyle ou éthyle ; R2 représente un radical alkylène en C1-C4 ; R3, R4 et R5 sont chacun indépendamment choisis parmi les radicaux alkyle en C1-C22 dont au moins un porte plus de 8 atomes de carbone, -CH2C6H5, -CH2CH2OH, -CH2OH et -(CH2)yNHC(O)R6 où y prend une valeur entre 2 et 10 et R6 représente un radical perfluoroalkyle en C1-C12 ; X est un chlorure, un bromure, un fluorure, un iodure, un acétate ou un tosylate ; et Z représente un cycle pyridinium de formule C5H5N+.
