美国最近研究成了一种名为“PAVER道面管理系统”。这是目前美国对机场道面和公路路面维护工作的最新科学管理方法。“PAVER道面管理系统”包括:道面状况评定、道面损坏鉴定手册、道面维修准则、维修方案经济分析、最佳维修方案选择以及道面损坏的预测等,此外,还有道面状况评定的电算程序。其中最核心的部分是道面状况评定。现把评定方法作一简要介绍。 (一)道面状况指数的概念无论哪一种道面管理系统,其关键部分是道面状况的评定,而“PAVER系统”用的是道面状况指数(Pavement Condition Index,缩写为PCI)作为道面状况好坏的 Recent research by the United States has become known as “PAVER Pavement Management System.” This is the latest scientific management method by the United States for the maintenance of airport pavements and road pavement. PAVER Pavement Management System includes: pavement condition assessment, pavement damage identification manual, pavement maintenance guidelines, maintenance program economic analysis, selection of the best maintenance options, and prediction of pavement damage, as well as pavement conditions Assessment of the computer program. The core of the assessment is the pavement condition. Now the assessment method for a brief introduction. (A) Concept of Pavement Condition Index The key component of pavement management system is pavement condition assessment, and PAVER System uses pavement condition index (PCI) Pavement condition is good or bad
