    摘要: To produce a composition to be used in road paving, mineral constituents such as gravel and/or crushed stone and sand with a bituminous binder are mixed in a mixer. To improve the strength characteristics of asphalt layers made with such a mixture in a simple, relatively cheap way chopped bundles of glass or mineral fibres are added to the composition in a percentage by mass of 0.2 - 0.8 with respect to the mineral constituents, the length of the filaments being between 5 and 50 mm, the diameter of the fila­ments at least 1 micrometer, and an adhesion-promoting protective coating being provided on the fibres. It is essential for the invention that the fibres are added in the mixture and not on the road and that the glass or mineral fibres are introduced into the composition in the form of bundles chopped to certain lengths.

    摘要: A surfacing mass especially for outdoor use and mainly comprising a mixture of asphalt and a stone material having a low content of fine material. The mixture comprises a little amount of fibres of a type which is not solved or softens in the asphalt, preferably mineral fibres. The fibre material has an average diameter of between 1 and 5 µm and is added in an amount of between 0,5 and 20 % by weight calculated on the amount of asphalt. The invention also relates to a method of manufacturing such surfacing mass at a mixing temperature of 140-170° C or preferably 150-160° C both for the asphalt and the stone mass. Preferably the fibre material is admixed in the asphalt before the mixing thereof with the stone material. The fibre material may be admixed in the asphalt at an asphalt temperature which is higher than the mixing temperature for asphalt and stone material.
