基于建养一体的干线公路沥青路面关键技术研究

Research on key technology of asphalt pavement for trunk highway based on integrated construction and maintenance

针对传统"建养一体化"模式仅解决了公路建设和养护之间的管理问题,尚未从技术角度解决公路建设和养护之间衔接不畅问题。通过调研江苏省干线公路典型病害,阐述了建养之间衔接不畅的根本原因,即信息、指标分离问题。基于建养一体化理念,通过室内试验验证,从干线公路沥青路面设计期、建设期等方面提出了建养一体技术提升方案,旨在解决干线公路建养之信息、指标分离问题,提升干线公路的使用性能,保证干线公路的高质量发展。

The traditional“integrated construction and maintenance”model only solves the management problem between highway construction and maintenance,but not the problem of poor connection between highway construction and maintenance from the technical perspective.Based on the investigation of typical trunk highway diseases in Jiangsu province,the paper expounds the root cause of poor connection between construction and maintenance,that is,the separation of information and index.Based on the concept of integration of construction and maintenance,through laboratory tests and verification,this paper puts forward a technical upgrading scheme of integration of construction and maintenance from the aspects of asphalt pavement design period and construction period of trunk highway,aiming at solving the problem of information and index separation of trunk highway construction and maintenance,improving the performance of trunk highway,and ensuring the high-quality development of trunk highway.
