The present invention proposes a roller for asphalt compaction, in particular a rubber tire roller, comprising: a rubber tire, a spray device for spraying a rubber tire with a separation agent mixture composed of a first liquid and a second liquid, a first tank for the first liquid and a second tank for the second liquid, characterized in that the rubber tire roller, in order to form the separation agent mixture, comprises a mixing device for mixing the first liquid supplied by the first tank and the second liquid supplied by the second tank. Further, the present invention relates to a method for spraying a rubber tire of a roller for asphalt compaction with a separation agent mixture.

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.

Disclosed are a rubber particle-doped composite chip seal and a construction method thereof. The chip seal includes: a coarse aggregate in a lower layer, a fine aggregate in an upper layer, and an SBS-modified emulsified asphalt binding and encapsulating the coarse aggregate and the fine aggregate into a whole, wherein the coarse aggregate is a gravel having a particle size of 4.75 mm to 7.1 mm, the fine aggregate is rubber particles having a particle size of 1.18 mm to 4.75 mm after pre-treatment, and the fine aggregate has a doping amount of 30% to 45% of a volume of all aggregates.
