Abstract:
1. A bituminous composition comprising a bituminous component (A), at least one elastomer component (B) selected from the group consisting of polydienes, copolymers of dienes with a monovinylaromatic hydrocarbon, polyacrylates, polysulfides, polysilicones and polyesteramides having elastomeric behavior, and an additive (C), wherein the additive is a compound having the general formula: wherein each “Ar” independently is a benzene ring or fused aromatic ring system of 6 to 20 carbon atoms, substituted by at least one hydroxyl group, and “R” is represented by the formula: wherein each “R 1 ” is a C1-4 hydrocarbonylene group, “R 2 ” is a C1-10 hydrocarbonylene group, and “X” is a nitrogen atom; and “n” is an integer having a value from 1 to 4, said elastomer component (B) being present in an amount in the range of from about 2 to about 20% wt and said additive (C) being present in an amount in the range of from about 0.01 to about 5 weight percent, based on the total bituminous composition.
