mixtures of bitumen, rubber crumb and the polymer binder products such as road

摘要

The present invention relates to mixtures of bitumen, rubber crumb and of at least one copolymer (a) of an alpha-olefin and at least one unsaturated epoxide, such as: - the brookfield viscosity at 180degrec according to the nft 76102 needle (27) is lower than 1150 mpa · s; - the difference in absolute value of the softening points (temperature of the ball / ring) according to nft 66008 between the top and bottom portions of a mixture is kept for 3 days at 180degrec in a vertical tube is less than or equal to 5degrec.ces mixtures are used as binders for roads.
