Abstract: The present invention relates to emulsions comprising a (1?3)-?-D-glucan, a cationic emulsifier and a bituminous binder having a low penetration. The emulsion is storage stable while fast breaking, even under unfavorable environmental conditions such as high humidity and low temperature. The emulsions can conveniently be used in chip less surface dressings, trackless tack coating compositions, water-proofing compositions, flooring applications, bonding layers, impregnation layers, dense coated materials and semi-dense coated materials which are cold-cast or storable, slurry seals, micro-surfacing compositions and mortars.

Abstract: The present invention relates to the use of a (1?3)-?-D-glucan as an emulsion stabilizer. The present invention further relates to emulsions comprising a (1?3)-?-D-glucan in an amount of 0.01 to 10 wt. %, based on the total weight of the emulsion. The present invention also relates to bitumen binder compositions comprising a (1?3)-?-D-glucan in an amount of 0.005 to less than 0.1 wt. %, based on the total weight of the bitumen binder composition. The present invention further relates to emulsions comprising a novel biodegradable emulsifying agent, in particular in combination with a (1?3)-?-D-glucan.

Abstract: The present invention relates to an essential colourless binder composition comprising a naphthenic oil having a total content of naphthenics of 35%-80% by weight, based on the total weight of the naphthenic oil, and a petroleum or synthetic hydrocarbon resin, wherein the ratio of the naphthenic oil and the petroleum or synthetic hydrocarbon resin is between 10:90 to 90:10. The essential colourless binder composition is suitable for use in coloured asphalt compositions and emulsions.

Abstract: The invention relates to a bituminous binder composition comprising: (a) 60-99.75 wt. % bitumen; (b) 0.05-5.0 wt. % of an elastomer; (c) 0.1-30.0 wt. % of a mono-alkyl ester of a vegetate e oil or an animal oil; and (d) 0.1-5.0 of an amide additive; based on the total weight of the bituminous binder composition, and a process for preparing the bituminous binder composition. The inventions further relates to the use of the bituminous binder composition in surface dressing, in particular road construction, road renovation, joint filling and sealing purposes.

Abstract: The invention relates to polyketone yarns of which the maximum tangential modulus at an elongation of more than 0.2% is at least 10 N/tex which display both high strength and, if so desired, a high elongation at break. The quality number, which is measured on a single filament out of a bundle of at least about 30 filaments spun simultaneously through one spinneret and given as .sigma., .epsilon., is higher than 85 mN/tex, preferably higher than 100 mN/tex. The quality number of a yarn spun through one spinneret of one or more holes is higher than 110 mN/tex, preferably higher than 120 mN/tex. The yarns are manufactured by extruding a solution of a linear polymer of alternating ethylene and carbon monoxide units in a resorcinol-containing solvent, after which the solvent is removed with the aid of methanol as coagulant.
