Modified sludge pyrolysis residue and application thereof in preparation of modified asphalt mixture
The invention provides modified sludge pyrolysis residues and application thereof in preparation of a modified asphalt mixture, and a preparation method of the urban sludge pyrolysis residues for asphalt slurry comprises the following steps: mixing urban sludge and a modifier according to a ratio, and pyrolyzing under a high-temperature anaerobic condition of 500-800 DEG C; the modifier is one or more of calcium oxide, calcium hydroxide and a flocculant. The town sludge pyrolysis slag for the asphalt slurry is fine in particle, has good mechanical properties, and can be well adhered to matrix asphalt. When the sludge pyrolysis residues are applied to the asphalt slurry, consumption of natural resources can be reduced, and an environment-friendly and feasible recycling means is provided for sludge treatment.
本发明提供改性污泥热解渣及其在制备改性沥青混合料中的应用，本发明的沥青浆料用城镇污泥热解渣的制备方法将城镇污泥与改性剂按比例混合，在500～800℃高温绝氧的条件下热解；改性剂为氧化钙、氢氧化钙和絮凝剂中的一种或几种。本发明的沥青浆料用城镇污泥热解渣颗粒细小，具有良好的力学性能，而且能够较好的与基质沥青粘附。污泥热解渣应用到沥青浆料中，既可减少自然资源的消耗，也为污泥的处理提供环保可行的资源化手段。
