Title: An integrated model of the climatic effects on pavements
Abstract: An integrated model is described in this report which combines and includes modifications to three separate models of climate effects on pavements: the Climatic-Materials-Structures Model (CMS) developed at the University of Illinois; the Infiltration and Drainage Model (ID) developed at Texas AM and the CRREL Frost Heave and Thaw Settlement Model developed at the United States Army Cold Regions Research and Engineering Laboratory (CRREL). The integrated model is intended for use on an IBM-compatible, 286 or 386 level microcomputer. Data are input with a full-screen data input program which generates the files necessary to run the integrated model program for a full simulated year. The input program has several full sets of default values which the user may elect to leave unchanged or modify as desired. Thirty year climatic data files for 15 cities representing 9 climatic regions in the United States make the weather data input simple, or if desired, different elements of weather data that are peculiar to a specific site may be input. Within the integrated model program, the weather patterns of rainfall, temperature, solar radiation, cloud cover, wind speed, and snow fall are simulated throughout an entire year. The weather patterns of temperature and rainfall may be set by the user to be as mild or as severe as desired. The program computes the pore water pressure, temperature, frost and thaw depth, frost heave, and layer materials elastic modulus with time. The computations are made in accordance with a numerical model of coupled heat and moisture flow in a medium with small volume changes. The third appendix includes a complete users guide to the integrated model program.
