A HEAT TRANSFER MODEL FOR EVALUATING FROST ACTION AND TEMPERATURE-RELATED EFFECTS IN MULTILAYERED PAVEMENT SYSTEMS

A HEAT TRANSFER MODEL FOR EVALUATING FROST ACTION AND TEMPERATURE-RELATED EFFECTS WAS DEVELOPED FOR A MULTI-LAYERED PAVEMENT SYSTEM. THE MODEL WAS DERIVED FROM ONE-DIMENSIONAL, FORWARD-FINITE-DIFFERENCE, HEAT-TRANSFER THEORY AND PROGRAMMED FOR COMPUTER SOLUTION. IT WAS DESIGNED TO INCLUDE INPUT PARAMETERS AND CAN BE EXPANDED TO INCLUDE NEWLY DEVELOPED PARAMETERS. IT IS USED TO EVALUATE THE TEMPERATURE REGIME OF VARIED PAVEMENT SYSTEMS IN DIFFERENT GEOGRAPHICAL LOCATIONS. METEOROLOGICAL PARAMETERS SUCH AS SHORT-WAVE RADIATION, LONG-WAVE RADIATION, CONVECTION, AND AIR TEMPERATURE ARE THE BASIC EXTRINSIC FACTORS IN THE HEAT-TRANSFER MODEL. INTRINSIC FACTORS CONSIDERED ARE THE PHYSICAL PROPERTIES AND THERMAL PROPERTIES OF THE PAVEMENT MATERIALS THAT INCLUDE UNIT WEIGHT, MOISTURE CONTENT, MATERIAL CLASSIFICATION, THERMAL CONDUCTIVITY, HEAT CAPACITY, AND LATENT HEAT. THE MODEL WAS DEVELOPED SO THAT APPROPRIATE THERMAL PROPERTIES OF THE PAVEMENT MATERIALS ARE USED DEPENDING ON WHETHER THE UNFROZEN, FREEZING, OR FROZEN STATE EXISTS. PAVEMENT TEMPERATURES GENERATED BY THE MODEL WERE COMPARED WITH LABORATORY TEMPERATURE DATA AND TEMPERATURE DATA FROM THE AASHO ROAD TEST, AND THE MODEL GAVE VALID RESULTS. USE OF THE MODEL FOR EVALUATING FROST ACTION IN A PAVEMENT SYSTEM AT A SPECIFIED LOCATION WAS DEMONSTRATED FOR 30 YEARS OF PAST CLIMATIC RECORD. IT WAS SHOWN THAT NECESSARY QUANTITATIVE DATA FOR THE EVALUATING COULD BE OBTAINED. A CLEARER UNDERSTANDING OF THE QUALITATIVE FACTORS INVOLVED IN FROST ACTION RESEARCH WAS ALSO PROVIDED. /AUTHOR/
