The aim of this paper is to study the feasibility of using an electrolytic manganese residue (EMR) as modified asphalt. In this paper, after grinding the electrolytic manganese residue (EMR) into asphalt, the electrolytic manganese residue- (EMR-) modified asphalt was prepared with different mix ratios. The three major indicators of the modified asphalt were studied, and its modification mechanism was studied by differential scanning calorimetry, infrared spectroscopy, and atomic force microscopy. The adhesion force, surface energy, and dissipation energy of the asphalt before and after modification were analyzed by a force curve. The results show that the surface energy of the electrolytic manganese residue (EMR) is increased after grinding, the high temperature performance of the asphalt is improved, and the temperature sensitivity of the asphalt is decreased; however, the low-temperature performance is not improved obviously. When the powder oil ratio is 9%, the comprehensive performance of the asphalt is the best. The results of the infrared spectrum analysis show that the mixture of the electrolytic manganese residue (EMR) and asphalt does not produce new functional groups, and thus, the preparation method is a physical modification method. The differential scanning calorimetry (DSC) results show that the electrolytic manganese residue (EMR) can enhance the high-temperature stability of asphalt. It is found that the stability and antideformation ability of the modified asphalt improved.

电解锰渣改性沥青性能测试及微力学分析

本文的目的是研究使用电解锰渣（EMR）作为改性沥青的可行性。本文将电解锰渣（EMR）磨成沥青后，制备了混合比不同的电解锰渣（EMR）改性沥青。研究了改性沥青的三个主要指标，并通过差示扫描量热法，红外光谱和原子力显微镜研究了其改性机理。通过力曲线分析了改性前后沥青的附着力，表面能和耗散能。结果表明，研磨后电解锰残留物（EMR）的表面能增加，沥青的高温性能得到改善，降低了沥青的温度敏感性；但是，低温性能没有明显改善。当粉末油比例为9％时，沥青的综合性能最佳。红外光谱分析结果表明，电解锰渣（EMR）和沥青的混合物不会产生新的官能团，因此，该制备方法是一种物理改性方法。差示扫描量热法（DSC）结果表明，电解锰残留物（EMR）可以增强沥青的高温稳定性。发现改性沥青的稳定性和抗变形能力得到改善。沥青的综合性能是最好的。红外光谱分析结果表明，电解锰渣（EMR）和沥青的混合物不会产生新的官能团，因此，该制备方法是一种物理改性方法。差示扫描量热法（DSC）结果表明，电解锰残留物（EMR）可以增强沥青的高温稳定性。发现改性沥青的稳定性和抗变形能力得到改善。沥青的综合性能是最好的。红外光谱分析结果表明，电解锰残留物（EMR）和沥青的混合物不会产生新的官能团，因此，该制备方法是一种物理改性方法。差示扫描量热法（DSC）结果表明，电解锰残留物（EMR）可以增强沥青的高温稳定性。发现改性沥青的稳定性和抗变形能力得到改善。差示扫描量热法（DSC）结果表明，电解锰残留物（EMR）可以增强沥青的高温稳定性。发现改性沥青的稳定性和抗变形能力得到改善。差示扫描量热法（DSC）结果表明，电解锰残留物（EMR）可以增强沥青的高温稳定性。发现改性沥青的稳定性和抗变形能力得到改善。
