Abstract

Ved en fremgangsmåte til fremstilling av fiber-holdig asfalt blandes tilslag, fiberpellets og bitumen ved en temperatur hvor bitumenen er flytende. Det tilsettes vannholdig fiberpellets, hvorved, idet den temperatur hvor bitumen er flytende er høyere enn vannets kokepunkt, oppvarmingen bevirker fordamping og ekspansjon av vannet i fiberpelletsen med medfølgende hurtig oppløsing av fiberpelletsen og fordeling av fibrene. Fiberpellets til bruk ved fremgangsmåten inneholder mest foretrukket ca. 20 vekt% vann, og består forøvrig hovedsakelig av et fibrøst materiale som er holdt sammen av et bindemiddel.In a process for the production of fibrous asphalt, aggregates, fiber pellets and bitumen are mixed at a temperature where the bitumen is liquid. Aqueous fiber pellets are added, whereby, as the temperature at which the bitumen is liquid is higher than the boiling point of the water, the heating causes evaporation and expansion of the water in the fiber pellets with consequent rapid dissolution of the fiber pellets and distribution of the fibers. Fiber pellets for use in the process most preferably contain approx. 20% by weight of water, and otherwise consists mainly of a fibrous material which is held together by a binder.
