为提升胶粉改性沥青的性能,以与基质沥青质量比为11/100的氯丁橡胶(CR)和3/100的乙烯-乙酸乙烯酯共聚物(EVA)为改性剂制备了改性沥青,采用低温等离子体活化CR/EVA以进一步提升复配改性沥青的性能,研究了单一改性、复配改性和低温等离子体活化复配改性沥青(A-CR/EVA-MA)的路用性能,并使用扫描电子显微镜、原子力显微镜和傅里叶变换红外光谱分析了各改性沥青的微观机理。结果表明,各改性沥青的路用性能均有提升,总体表现为活化复配改性优于复配改性和单一改性;A-CR/EVA-MA的针入度、软化点、延度、布氏黏度及抗车辙因子较基质沥青分别提升了46%、47%、95%、253%和278%,存储稳定性也得到了进一步提高;低温等离子体活化技术增加了改性剂的比表面积和表面官能团含量,提高了改性剂对沥青中轻质组分的吸附能力,促进了CR和EVA与沥青的紧密结合,有效提升了改性沥青的路用性能。

In order to improve the performance of crumb rubber modified asphalt, chloroprene rubber (CR) with a mass ratio of 11/100 to matrix asphalt and ethylene-vinyl acetate copolymer (EVA) with a mass ratio of 3/100 were used as modifiers to prepare modified asphalt. CR/EVA was activated by low-temperature plasma to further improve the performance of compound modified asphalt. The road performance of single modified, compound modified and low-temperature plasma activated compound modified asphalt (A-CR/EVA-MA) were studied. The microscopic mechanism of each modified asphalt was analyzed by scanning electron microscopy, atomic force microscopy and Fourier transform infrared spectroscopy. The results showed that the road performance of each modified asphalt was improved, and the overall performance of the activation modification system was better than those of compound modification and the single modification system. The penetration, softening point, ductility, Brookfield viscosity and anti-rutting factor of A-CR/EVA-MA increased by 46%, 47%, 94%, 253%, and 278% respectively compared to the matrix asphalt, and the storage stability was also further improved. The low-temperature plasma activation technology increased the specific surface area and surface functional group content of the modifier, improved the adsorption capacity of the modifier to the light components in the asphalt, promoted the close combination of CR, EVA and asphalt, and improved effectively the road performance of the modified asphalt.
