摘　　要：对近年来广东地区高速公路路面养护方法进行整理,分析了NovaChip、沥可贴、微表处、高粘弹超薄磨耗层和超级微表这5种处理措施。结果表明,NovaChip、沥可贴、高粘弹超薄磨耗层能有效改善路面表观状况,降低SFC和路面噪音,路面渗水系数和构造深度均能满足设计要求;微表处方法的耐久性能显著,路面进行微表处养护7~8年后,PCI、SFC和RD均能保持较高的水平,衰减值很小;采用超级微表处置路面工后1年内,路面表观状况随着时间增长而逐渐改善,SFC随着时间增长而逐渐减小,路面渗水系数和构造深度均能满足设计要求,路面噪音有小幅增大。This paper sorts out the maintenance methods of highway Pavement in Guangdong in recent years,and analysis NovaChip,pasting asphalt,micro surfacing,high viscoelastic ultra-thin wearing layer and super micro surfacing.The results show that NovaChip,pasting asphalt and high viscoelastic ultra-thin wearing layer can effectively improve the surface condition of pavement,reduce SFC and pavement noise,and the water permeability coefficient and structure depth of pavement can meet the design requirements;the durability of micro surfacing method is remarkable,PCI,SFC and RD can maintain a high level after 7-8 years of micro surfacing maintenance,and the attenuation value is very small;super micro surfacing treatment is adopted Within one year after the pavement construction,the surface condition of the pavement gradually improves with the increase of time,and the SFC gradually decreases with the increase of time.The seepage coefficient and structural depth of the pavement can meet the design requirements,and the pavement noise increases slightly.
