摘要

隨著國道高速總里程數之不斷增加，對於路面問題之檢測必須具備維持鋪面完整及量測迅速之特性，以增進檢測效率，並減少對交通及社會成本之衝擊。
因此本研究針對落重撓度儀(Falling Weight Deflectometer,簡稱FWD)，建立一套工地檢測資料輸入管理系統，本系統包括資料庫軟體選用、系統傳輸方式、檢測路段長度之決定及資料庫設計。本研究採用Microsoft Access 2000軟體撰寫資料庫，其中資料庫的內容，包含舖面起始資料及檢測資料兩大部份，在現地所需記錄的資料則有檢測相關資料、舖面現況調查及落重式撓度儀之撓度值。就FWD而言，檢測一點的範圍為5m，並考慮到隨機性，故本研究在選擇檢測路段長度時，以100m為一單位。若舖面狀況指數（PCI, Pavement Condition Index）低於60時，則增加檢測次數，以50m為一單位。在工地則以個人數位助理（Personal digital assistant, PDA）做為輸入工具，再利用USB同步底座將PDA與電腦的資料互相同步化。故本研究結果顯示，運用落重式撓度儀(FWD)之非破壞性撓度檢測，並配合工地檢測資料輸入管理系統，可有效提升檢測效率。

To meet the continuously construction of the total mileage of the National Freeway system, a better pavement question investigation approach has become necessary. With a new approach that can keep the investigated section intact and fast to perform, the efficiency of whole investigation process can be increased and the impact on traffic and cost to the society can both be lowered.
Therefore, the research presents a field investigation information input and management system specially designed for Falling Weight Deflectometer. Research works include the selection of database Management System, the protocol of system transmission, length determination of each investigated section, and development of the Database system. Microsoft ACCESS 2000 was selected to develop platform for the final product. The back ground information for each investigated section (such as beginning/ending stations and others) and corresponding field data readings are the two major parts of the information stored in the database system.
In situ, background information of each investigation, current conditions of the investigated pavement and deflection readings from FWD were needed to be entered into the system. For each FWD investigation, the effective range for each test is 5 meters. Considering the significance of random sample, it is recommended by this research that the segment length should be 100 meters for each investigation. If the Pavement Condition Index (PCI) is less than 60, it is recommended that the frequency of investigation have to be increased. In other words, the segment length should be 50 meters instead of 100 meters.
PDA (Personal Digital Assistant) is to be used in the field as the information gathering tools. Using USB (Universal Serial Bus), the data between PDA and computer can be synchronized.
The conclusions of this research show that the incorporation between the Non-Destructive Deflection Investigation of FWD and the field investigation information input and management system can significantly increase the efficiency of the pavement evaluation.
