目前公路運輸是國人最主要之運輸工具, 所以, 如何在適當的時機
進行路面養護工作, 保持路面在一定標準之服務水準, 以確保行的安全性
及舒適性, 是所有養路單位急欲得知及解決的問題, 而在過去國內鋪面相
關研究中大多以鋪面績效指標的建立或養護路段的優先排序為研究重點,
而對於鋪面養護週期的研究並不多, 因此, 本研究以鋪面影響因子建立鋪
面養護週期預測模式, 提供養路單位進行決策時之參考. 本研究以柔
性鋪面為研究範圍, 針對鋪面績效影響因子進行整理探討後, 依國內目前
資料保存現況, 選定小客車當量交通量, 標準軸重當量, 降水量, 日照時
數和溫差五個鋪面影響因子作為鋪面養護週期預測模式的預測變數, 進行
養護週期預測模式的建構, 以公路局第四區工程處轄內宜蘭縣境內之公路
為研究範圍, 收集歷年之養護作業及影響因子之歷史資料, 進行實證分
析, 建立鋪面養護週期預測式, 並以統計方法進行預測式之檢定工作.
本研究並將鋪面養護週期預測模式加入地理資訊系統之概念, 以研究範圍
為例, 初步設計一簡單查詢系統之雛形, 可直接以數位化地圖介面查詢各
路段之屬性資料, 或藉由查詢條件選取的方式進行資料查詢, 其顯示方法
可為表格顯示和數位化地圖顯示兩種, 讓使用者能進一步了解路段間的空
間關係.

Land transportation is the major transportation mode
islandwide in Taiwan. Keeping road surface condition at a
satisfactory level os service,such as in terms of safety and
comfort, are the principal objectives to achieve for road
maintenance agencies. Previous studies on pavement management
have mostly focused on building pavement (PPI) or
prioritizingpavement rehabilitation. The primary purpose of the
study is therefore to build a model for predicting the cycle
time of pavement rehabbilitation using the factors that affect
pavement performance. Consider the availability of collected
data, the scope is limited to the flexible pavement type with
the chosen influential factors. includingtraffic volume (in
pcu), equivalent single axel load (ESAL), precipitation,daytime
period and temperature difference. Historical data on the chosen
variables in I-Lan were collected from the fourth regional
branch, TaiwanHighway Brueau. The collected raw data were coded,
screened by deleting unresonable values, reorganized and
standardized, and then used to calibratepredictive model for the
cycle time of pavement rehabilitation. Statisticalmethods are
used to test the validity of the calibrated regression models.
The proposed predictive models for the cycle time of areawide
pavement rehabilitation in combination with the collected
historical data are thencoded into GIS (Geographic Information
System) data base as spatial attributes. Users may select
either tabular or mapping type to display roadsegment that match
user''s specifications.
