Zusammenfassung:	Sludge mixts. (A)(including asphalt-type substances and cracked lubricating oil residues) obtd. in reclaiming waste oils comprises addn. of elastomer (B) and hardeners (C) and use of the mixt. in road-surfacing work, waterproofing of cardboard and felt etc., sealing of dams, etc. Component (B) is pref. an ethylene/propylene terpolymer. Component (C) is pref. powdered isotactic polypropylene. An ''optimal cpd.'' (D) pref. comprises 66% of sludge from method (i), 17% EPDM elastomer (powdered, 600-800 microns) and 17% isotactic polypropylene (powdered, 600-800 microns). It is mixed at 180-190 deg.C until homogeneous. A compsn. (E) suitable for road surfacing can then be made by mixing 20-40% (pref. 25%) of (D) with distilled bitumen of type 180-200 and forming the mixt. into small loaves. These loaves can be mixed with various proportions of hot aggregate to form road surfacing materials with temp.-resistance of -25 to 150 deg.C.
