Modified asphalt mortar based on oily sludge pyrolysis residues, and preparation method thereof
The invention relates to modified asphalt mortar based on oily sludge pyrolysis residues, and a preparation method thereof. The method comprises the following steps: mixing the oily sludge pyrolysis residues with a preset substance in a dry state to prepare a filler; adding water into the filler to prepare a viscous fluid; standing the viscous fluid for a preset time to prepare a mixture; performing drying treatment on the mixture to prepare a mixed filler; and preparing the mixed filler into the modified asphalt mortar. The modified asphalt mortar prepared by the invention is residues subjected to mineral powder composite modification, and the high-temperature performance of the modified asphalt mortar is obviously superior to that of mineral powder asphalt mortar. The low-temperature performance of the modified oily sludge pyrolysis residues is obviously superior to that of mineral powder asphalt mortar. After the oily sludge pyrolysis residues replace part of mineral powder and are modified by the slaked lime, various properties of the oily sludge pyrolysis residues are obviously superior to those of mineral powder asphalt mortar, so that the problems of insufficient high-temperature performance and water stability caused by single modification of the oily sludge pyrolysis residues are solved, and the pavement performance is very good.
本发明涉及一种基于油污泥热解残渣的改性沥青胶浆及其制备方法，方法包括：在干燥状态下将油污泥热解残渣与预设物质进行拌合以制备填料；在所述填料中加入水制成粘稠状流体；将所述粘稠状流体静置预设时间以制备混合物；对所述混合物进行干燥处理，以制备混合填料；将所述混合填料制备成改性沥青胶浆。本发明所制备的改性沥青胶浆是经矿粉复合改性后的残渣，其高温性能明显优于矿粉沥青胶浆。改性后的油污泥热解残渣的低温性能明显优于矿粉沥青胶浆。油污泥热解残渣代替部分矿粉后经过消石灰改性后其各项性能明显优于矿粉沥青胶浆，解决了单一用油污泥热解残渣改性存在的高温性能、水稳定性能不足的问题，有很好的路用性能。
