路面养护急需不受气候条件限制且能快速紧急修补的养护材料,笔者针对安徽省自然地理气候特征,研制出3种复合型聚合物改性剂和冷补沥青混合料(简称AH型冷补沥青混合料),提出了相应的技术指标、适用范围和关键施工工艺。实践表明:该材料能在低温、常温及潮湿等条件下对路面坑槽进行快速修补,使用效果良好。 Pavement maintenance urgent need not subject to climatic conditions and rapid emergency repair of maintenance materials, the author for the natural geography and climate in Anhui Province, developed three kinds of composite polymer modifier and cold-asphalt mixture (referred to as AH cold-asphalt Mixture), put forward the corresponding technical indicators, the scope of application and key construction technology. Practice shows that: the material can be quickly repaired at low temperature, room temperature and humidity conditions, the use of good effect.
