| 摘 要： | 根据基准沥青性状，ＥＶＡ的醋酸乙烯脂含量与熔融指数，以及性能改善的预期目标，采用多元共混方式使基准沥青的强度，韧性，粘性和温度稳定性均有明显提高。形成一种路用品质优良的树脂改性沥青。通过常规和专项性能测试，证实了这种ＥＶＡ改性沥青制配成的沥青混凝土能减缓沥青面层低温开裂损坏，提高结构整体强度，减少高温永久变形的累积，从而明显延长了面层的使用寿命。

| Abstract: | According to base asphalt properties, vinyl acetate content and melting point of EVA, and modify aim, a resin modified asphalt is produced by hotmelting and mixing. Through a series of formal and specialized tests, the results show that the EVA modified asphalt mixture can decrease lowtemperature fatigue cracks and the high-temperature accumulated rut depth of the asphalt pavement, and can prolong its working life. |
