RIGID PAVEMENT INVESTIGATIONS-GROWTH CHARACTERISTICS AND BLOWUPS AND PERFORMANCE OF TRANSVERSE JOINTS AND JOINT SEALING MATERIALS

THE MAIN OBJECTIVES OF THIS INVESTIGATION ARE (1) TO MEASURE THE "FIELD GROWTH" OF RIGID PAVEMENTS, SO THAT BETTER PERFORMING AGGREGATE TYPES CAN BE DETERMINED AND (2) TO DETERMINE THE REASONS FOR "BLOWUP" OCCURRENCES ON RIGID PAVEMENTS. IN THE FIELD INVESTIGATION OF CONCRETE GROWTH, THE OVERALL LENGTHS OF ALL TEST SITES ARE INCREASING. THE CONCRETE IN TWO STONE CONTRACTS APPEARS TO BE GROWING, WHEREAS, THE CONCRETE ON THE ONE GRAVEL CONCRETE APPEARS TO BE SHRINKING. THE RESULTS AT THIS TIME HOWEVER ARE INCONCLUSIVE. IN THE INVESTIGATION OF BLOWUPS, THE RESULTS TO DATE INDICATE THAT THE PROBABILITY OF A BLOWUP IS CONSIDERABLY GREATER AT AN EXPANSION JOINT THAN AT A CONTRACTION JOINT. ALSO, THE PROBABILITY OF A BLOWUP IS GREATER ON A PAVEMENT BUILT USING GRAVEL AGGREGATE THAN ONE BUILT USING A STONE OR SLAG AGGREGATE. PAVEMENT AGE IS ALSO A SIGNIFICANT FACTOR IN BLOWUP OCCURRENCES.
