Abstract: The invention provides a process for preparing a bitumen composition comprising blowing a mixture with an oxygen-containing gas which mixture comprises a bitumen having a penetration of less than 300 dmm (as measured by ASTM D 5 at 25.degree. C.), a thermoplastic rubber which is present in an amount of less than 10% w, and a bitumen blowing catalyst which is present in an amount of more than 0.5% w and up to 3% w, both based on total mixture; and bitumen compositions obtainable by such process.

Abstract: The invention provides a process for preparing a bitumen composition comprising blowing a mixture with an oxygen-containing gas which mixture comprises a bitumen having a penetration of at least 300 dmm (as measured by ASTM D 5 at 25.degree. C.), a thermoplastic rubber which is present in an amount of less than 10% w, and a bitumen blowing catalyst which is present in an amount in the range of from 1 to 3% w, both based on total mixture; and bitumen compositions obtainable by such process.

Abstract: The present invention provides a process for preparing a bitumen composition which comprises mixing at an elevated temperature an oxidised bitumen having a penetration index of at least 0 with a thermoplastic rubber which is present in an amount of less than 5% wt., based on total bitumen composition; bitumen compositions obtainable by such process; and the use of such bitumen compositions in asphalt mixtures for road applications.

Abstract: A bituminous composition comprising:(a) from 99 to 85% w of a mixture of:(1) 45 to 99.8% w of a bituminous component having a penetration of at least 800 dmm at 25.degree. C.;(2) 0.1 to 30% w of a lithium salt of a C.sub.10-40 fatty acid or hydroxy fatty acid;(3) 0.1 to 25% w of an elastomer; and(b) from 1 to 15% w of an amorphous silica filler.

Abstract: A process is disclosed for the preparation of a hydrocarbonaceous distillate and a hydrocarbonaceous residue, which comprises mixing a residual fraction of a product obtained by catalytic cracking or hydrocracking a hydrocarbonaceous feedstock, with a second hydrocarbonaceous fraction having such a boiling range that at least 50% w boils at a temperature above 400.degree. C., and subjecting the resulting mixture to a subatmospheric distillation yielding at least one distillate fraction and one residue. The residue thus prepared is a suitable component in bitumen compositions.

Abstract: A composition which contains (a) 80 to 99% w of a bitumen component; (b) 1 to 20% w of an elastomer; (c) 1 to 60% w of a hydrocarbon resin which has been modified to contain carboxyl, carboxylic anhydride, hydroxyl and/or amino groups; and (d) 1 to 100% w of an inorganic filler, the weight percentages being based on the total weight of the bitumen component and elastomer, is suitable for coating structures and a process for applying the composition at elevated temperature onto a suitbale structure.

Abstract: A binder composition which is pigmentable comprising from 30 to 99 wt % of a mineral lubricating oil extract and from 70 to 1 wt % of a petroleum resin and/or coumarone-indene resin, characterized in that the petroleum resin and/or coumarone-indene resin contains moieties derived from carboxylic acid, carboxylic acid anhydride or hydroxyl groups.

Abstract: Plastic bituminous compositions comprising(a) 100-30 % w of a mixture of1. 45-99.8 % w of a bituminous component having a penetration of less than 800 (0.1 mm) at 25.degree. C.,2. 0.1-30 %w of a lithium salt of a C.sub.10 -C.sub.40 (hydroxy) fatty acid, and3. 0.1-25 %w of a thermoplastic polymer, and(b) 0-70 %w of a filler having excellent self-adhesive properties even when applied on wet or wetted surfaces. They are cold applicable and shear-stable.
