VIBRATING PAN TYPE FINISHING MACHINE FOR CONCRETE PAVEMENTS

FOR THE PURPOSE OF INVESTIGATING THE EFFICACY OF THE VIBRATING PAN TYPE OF FINISHING MACHINE, ONE OF THESE MACHINES WAS USED IN THE CONSTRCTION OF A 20 FOOT CONCRETE PAVEMENT. TWO SERIES OF CONCRETE MIXTURES WERE USED. IN ONE THE CEMENT FACTOR WAS KEPT CONSTANT WHILE THE RATIO OF FINE TO COARSE AGGREGATE WAS VARIED; IN THE OTHER SERIES THE CEMENT FACTOR WAS VARIED. BEAMS, 2 FT. BY 5 FT. WERE REMOVED FROM THE PAVEMENT, TESTED FOR FLEXURAL STRENGTH AND OBSERVED FOR HONEYCOMBING, AND TESTED FOR DENSITY. ONE SET WAS THEN TESTED FOR COMPRESSIVE STRENGTH AND THE OTHER SET SUBJECTED TO FREEZING AND THAWING IN AN ATTEMPT TO DETERMINE RELATIVE DURABILITY. THE RESULTS INDICATE THAT THIS TYPE OF MACHINE CAN FINISH CONCRETE MIXTURES WHICH ARE MUCH LEANER, HARSHER AND DRIER THAN MIXTURES ORDINARILY CONSIDERED SUITABLE FOR PAVEMENT CONCRETE. /AUTHOR/
