MICROWAVE HEATING FOR ROAD MAINTENANCE

THE REPORT DESCRIBES A ONE YEAR FEASIBILITY STUDY TO DETERMINE THE APPLICABILITY OF MICROWAVE POWER IN CONJUNCTION WITH POLYMER CONCRETE (POLYMERS PLUS AGGREGATE) FOR HIGHWAY MAINTENANCE. THE SPECIFIC CONCERN WAS RELAIVE TO CONCRETE BRIDGE DECKS. WORK COVERED IN THE REPORT INCLUDES THE DEFINING OF POLYMERIZATION PARAMETERS AND OPTIMUM MATERIALS COMBINATIONS TO BE RAPIDLY CURED IN-SITU WITH MICROWAVE POWER. IN THE PORTION OF THE PROGRAM CONCERNED WITH MICROWAVE EQUIPMENT, A FIELD UNIT WAS DESIGNED, BUILT AND TESTED. THIS UNIT WAS USED FOR FIELD TESTING ALONG WITH A SERIES OF MICROWAVE APPLICATORS DESIGNED AND BUILT UNDER THE PROGRAM. WITH THE MATERIALS AND EQUIPMENT COBINED, THE RESEARCH TEAM IS ABLE TO FILL A VOID IN A CONCRETE SECTION AND COMPLETELY CURE THE PATCH IN LESS THAN THREE MINUTES.
