The present invention relates to a bitumen composition comprising a petroleum slack wax and a Fischer-Tropsch wax, the use of the waxes in bitumen compositions, the use of the bitumen composition in asphalt compositions, asphalt compositions comprising the bitumen composition and a method for producing asphalt pavements and constructions thereof. The bitumen has proved to have better processing characteristics.

Bitumen composition comprising a wax mixture consisting of a petroleum slack wax and a Fischer-Tropsch wax, the use of the wax mixture in bitumen compositions, the use of the bitumen composition in asphalt compositions, asphalt compositions comprising the bitumen composition and the method of producing asphalt pavements thereof

Microcrystalline paraffin having a consistency in a rage of paste-like to solid, prepared by catalytic hydroisomerization of FT paraffins having a carbon chain length distribution in a range of 20 to 105 at temperatures above 200&#xb0; C., and being free of aromatic compounds, heterocyclic compounds, and naphthenes.

Microcrystalline paraffin, method for producing microcrystalline paraffins, and use of the microcrystalline paraffins

A method for producing bulk good of agglomerates made of rubber particles and wax. A composition of the agglomerate and the use of the bulk good to produce asphalt or bitumen masses are created in that rubber is activated by swelling and using a swelling agent and a melt made of viscosity-reducing wax and of optional polyoctenamer is added, the activated rubber particles are agglomerated by means of the viscosity-reducing wax and optional adhesion-improving substances. The resulting larger volume leads to a viscosity reduction and the softening leads to a more intimate and more homogeneous wetting with the wax and, in the mixed good to be produced, a viscosity reduction remaining stable in the mixed good for &#x3c;180 min and an increased stability of the cross-linking of the rubber molecules among each other after the agglomerates have been incorporated are achieved.

Method for producing agglomerates having rubber and wax, agglomerates produced according to the method, and use of the agglomerates in asphalt or bitumen masses

The invention relates to a novel and completely synthetic microcrystalline paraffin, said paraffin being obtained in a simple manner and with a high yield by the catalytic hydromerisation of paraffin FT comprising 20 to 105 carbon atoms. Said paraffins can be pasty to solid at room temperature and have a higher percentage of iso-paraffins than n-paraffins. Since they do not contain aromatic compounds they are particularly suitable for use in the pharmaceutical, cosmetic and food industries.
