摘要：A method and apparatus for manufacturing a coating mass for roadconstructions are disclosed wherein stone minerals of different grain size ranges aredosed, dried, heated, dusted off and supplemented with a binding agent and other fluxmaterials. The stone minerals of the various grain size ranges are separated from eachother and are predosed, dried and heated. This divides the stone minerals of each grainsize range into a stone fraction and a respectively absorbed fine grain size material whichis divided into a sand fraction and a self filler fraction by means of filtering, the sandfraction is thereafter added again to the stone fraction of the respective grain size range,and the self filler fractions of all grain size ranges are combined weighted. All of theheated stone and sand fractions are also weighted and combined and are mixed togetherwith the combined and weighted self filler fraction, and the binding agent in order toprovide the coating mass.
