Abstract: Method and apparatus for the manufacture of one-dimensional or multi-dimensional curved or angularly formed, preferably moldings of mineral wool, which is impregnated with a binder, in that a matching or chosen piece of binder impregnated mineral wool felt (9) or mineral wool is compressed between mold parts comprising a matrix (4) and a counter die (1), whereafter the matrix (4) and/or the counter die (1) cures the binder of the mineral wool body formed by the matrix and the counter die, whereby the mineral wool felt (9) is compressed in two or several steps, namely in at least a first step between the counter die (1) and a portion (5) of the matrix (4), whereafter the remaining part (6) of the matrix (4) in one or several successive steps is fold or pressed to the mineral wool felt (9), so that all remaining parts thereof are pressed to the counter die (1), whereby all parts of the mineral wool felt (9) is given a predetermined thickness.

Abstract: 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 .mu.m 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.degree.-170.degree. C. or preferably 150.degree.-160.degree. 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.
