ENVIRONMENTAL EFFECTS ON PAVEMENTS. VOLUME 3: THEORY MANUAL. FINAL REPORT

The Climatic-Materials-Structural (CMS) program has been set up to analyze multilayered flexible pavement systems. The program may be used in conjunction with structural and pavement performance models to analyze a pavement system. It can also be employed as a tool to analyze existing pavement systems in order to obtain estimates of future maintenance requirements. The CMS model is compatible with several pavement structural models for determining radial stresses, strains, and displacements. These structural models include the ILLI-PAVE model, ILLI-PAVE algorithms, elastic layer analysis, and the VESYS II M program. The accuracy of the CMS output depends mainly on the quality of the inputs. It is important that the boundary conditions, climatic conditions, and material properties properly represent the system to be analyzed. With representative inputs the CMS program will give realistic values for the temperature profile and the material stiffness properties. Although future research is required in order to validate the overall model, the validity of the individual parts comprising the CMS model have been shown. Analysis of existing pavement systems and comparison of the CMS outputs with actual field conditions are recommended. It is expected that further validation studies will confirm the belief that the CMS model provides an economical and realistic means of analyzing multilayered flexible pavement system by accounting for climatic effects on the pavement materials. A separate User's Manual provides a detailed description for programming the CMS model.
