• 中文摘要： 路面及其下各層受氣象影響甚大。環境的作用改變各層材料性質的效果，可從測量路面撓度求出。本文提出路面溫度及 路床含濕變化之影響及預測材料性質的方法構架。利用數?法與電腦程式決定各層彈性係數之「?實?」，並?實例說明。 此報告及電腦程式可被納入一完整廣博的路面設計系統，成?道路評估與維護次級系統一部份。
• 英文摘要： Pavement and its underlying layers are exposed to strong climatic influences. The environmental effect on layer material properties may be characterized from surface deflection measurements. The framework of methodology in predicting layer properties as affected by changes in pavement surface temperature and subgrade moisture content have been proposed. A numerical method along with a computer program for determining the "in-situ" layer moduli, and a sample test section have been presented. This report and the computer program maybe used as a part of pavement performance evaluation and maintenance subsystem of a comprehensive pavement design system.
