市區道路柔性鋪面管理與維護準則研究

MANAGEMENT AND MAINTENANCE CRITERIA FOR THE FLEXIBLE PAVEMENT OF THE CITY STREET NETWORK

市區道路的鋪面養護由於缺乏專責組織及人員，僅能依據都市地區人口及市區道路總面積作為配額計算基準，致道路維護資源不易確實用於急需之路段上，故使全體的市區道路服務水準不一。內政部營建署有生於此，為協助地方政府解決市區道路管理及維護問題，目前正積極訂定市區道路管理維護技術規範及建立客觀的鋪面服務能力評估準則，作為每年補助市區道路管理機關維護經費配額的基準。本研究乃依此目標建立市區道路維護之具體內容，並規劃路段劃分及損壞調查方法。本研究考量現階段鋪面檢測能力，故建置之養護決策及養護計畫仍以損壞調查為主，地方政府可依此管理維護技術，建立鋪面管理機制及系統化之養護作業，研擬標準化的鋪面服務能力評估程序及提供客觀的養護需求判斷準則，使有限的道路維護資源能作合理之分配，並使所有市區道路皆保持在一定服務水準之上。

The budget distribution of city street pavement maintenance is generally based on the total pavement area and the city population currently. This may easily cause the unevenness of resources allocation and non-standardized pavement performance for all cities. The Construction and Planning Administration (CPA) is actively setting up a standardized pavement management and maintenance system for the city street network and allocating the limited sources for pavement maintenance based on the uniform evaluation procedure. The major objective of this study is to identify the main contents that shall be included in the specified pavement management system and develop the pavement network coding methodology as well as the standard procedure for pavement condition survey. The maintenance decision tree based upon the collected pavement condition data is also developed in this paper. The CPA has accepted and planned to use the developed system for trial basis in the coming years for the central evaluation and budget allocation for city street pavement networks.
