摘　　要：为研究维他连结剂(trans-polyoctenamer rubber reactive modifier,TOR)橡胶沥青在路面养护中的适用性,通过室内试验,基于沥青玛蹄脂碎石(stone matrix asphalt,SMA)级配制备了湿法TOR橡胶沥青混合料,测试其路用性能;依托江苏省道S333邮仪段大中修罩面工程进行了试验路的摊铺和现场检测.室内试验结果表明:TOR橡胶沥青混合料的各项路用性能均满足现行改性沥青混合料规范要求;现场施工及检测结果表明:TOR橡胶沥青混合料具有良好的施工和易性、节能环保等特点,且试验路各项检测指标均满足公路沥青路面施工规范要求.TOR（trans-polyoctenamer rubber reactive modifier） rubber asphalt is a new type of modi- fied rubber. In order to study its application in pavement maintenance, wet process TOR rubber asphalt mixture with SMA （stone matrix asphalt） grading is prepared and its pavement performance is studied by laboratory tests. A test road is paved and field detected in the overlay project of 333 provincial highway. The results of laboratory tests show that the pavement performance of TOR rubber asphalt mixture can satisfy the standard requirement. The results of paving and field detec- tion indicate the perfect workability and environmental characteristics of TOR rubber asphalt mix- ture, and the testing indexes of the test road can meet the standard requirement well.
