Document Type and Number:
Japanese Patent JP2002537435
Kind Code:
A
Abstract:
A modifier to improve the performance of bituminous mixtures used in the road paving, whose modifier is easily dispersible at any ratio in the bituminous mixtures, and leads to a mixture with improved properties as compared with traditional bituminous mixtures. The modifier comprises a concentrated dispersion of a polymer in a heavy oil fraction coming from petroleum refining operations, in the presence of fillers like those used in the manufacture of bituminous mixtures for roads. Besides these three main components (polymer, heavy oil fraction and fillers), the modifier according to this invention may contain, if desired, other components such as adhesiveness promoters. These components are mixed in equipment such as those used to compound rubber.
