Sludge pyrolysis residue modified asphalt mixture and preparation method thereof
The invention provides a sludge pyrolysis residue modified asphalt mixture and a preparation method thereof, the modified asphalt mixture comprises the following components in parts by weight: 30-70 parts of modified sludge pyrolysis residue, 10-30 parts of gravel, 5-15 parts of natural sand, 30-70 parts of mineral powder and 3.75-14.5 parts of asphalt; the preparation method of the modified sludge pyrolysis slag 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; according to the sludge pyrolysis slag modified asphalt mixture, the modified sludge pyrolysis slag is used as a raw material component, the environmental problem caused by sludge accumulation is solved, consumption of natural resources can be reduced, an economical and feasible resource utilization mode is provided for sludge treatment, and the asphalt mixture is matched with other grading components, so that the utilization rate of the asphalt mixture is improved. The high-temperature rutting resistance of the asphalt mixture is improved, and the performance of the mixture is improved.
本发明提供了一种污泥热解渣改性沥青混合料及其制备方法，本发明的改性沥青混合料包括以下重量份的组分，改性污泥热解渣30～70份、碎石10～30份、天然砂5～15份、矿粉30～70份和沥青3.75～14.5份；改性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。本发明的污泥热解渣改性沥青混合料应用改性污泥热解渣作为原料组分，解决了污泥堆积造成的环境问题，可减少自然资源的消耗，也为污泥的处理提供经济可行的资源化利用方式，而且与其他的级配组分搭配，提高了沥青混合料的高温抗车辙性，改善了混合料的性能。
