CLIMATOLOGICAL LITERATURE PERTAINING TO PERFORMANCE OF HIGHWAY CONCRETE
CURRENT LITERATURE REGARDING THE EFFECTS OF ENVIRONMENTAL FACTORS ON THE SERVICEABILITY OF CONCRETE PAVEMENTS IS EXPLORED. THE BASIC PARAMETERS ARE THOSE COMPRISING THE CLIMATIC DOMAIN. HOWEVER, WIDE VARIATIONS OF THESE PARAMETERS (E.G., TEMPERATURE) CAN OCCUR OVER RELATIVELY SHORT DISTANCES WITHIN A GIVEN CLIMATIC DOMAIN BECAUSE OF TOPOGRAPHIC, GEOLOGIC, HYDROLOGIC, AND FLORAL DIFFERENCES. THUS, WHILE THE PROBLEM IS RELATED TO MICROCLIMATE, THE MEASUREMENTS AND DATA CURRENTLY AVAILABLE ARE OF THE MACROSCALE. IT IS CONCLUDED THAT IF THE PREDICTION OF EXTREME OCCURENCES IN MICROENVIRONMENTAL CONDITIONS LEADING TO LOCALIZED DETERIORATION OF CONCRETE PAVEMENT COMPONENTS IS TO BE REALIZED, IT WILL FIRST BE NECESSARY TO DETERMINE THE CRITICAL LIMITS OF THE ENVIRONMENTAL PARAMETERS, INDIVIDUALLY AND IN COMBINATION, AND THE DEVELOPMENT OF THE TECHNOLOGY TO PREDICT ACCURATELY THE OCCURRENCES OF THE CRITICAL CONDITIONS. /AUTHOR/
