Environment is one of the essential factors that influence pavement material behavior and consequently its performance. The variation of climatic patterns from region to region coupled with the variation of site specific conditions across North America make it difficult to develop standard models to account for seasonal variation in material properties for all regions. Therefore, the need to develop regional models becomes an essential requirement for most transportation departments. The Enhanced Integrated Climatic Model (EICM) was used to determine its suitability in predicting subsurface temperature and moisture conditions within New Jersey sites. The validation of the model was carried out using environmental data collected through pavement instrumentation as part of a large-scale research study being undertaken under the sponsorship of the New Jersey Department of Transportation (NJDOT). The validation was carried out using site-specific data as input to the model and compared the model output parameters against field-measured values. This paper reports the results of the validation for two of the instrumented sites. Results of the study do not indicate a high correlation between EICM-predicted temperature and moisture profiles for the various pavement layers as compared to measured values.
