EXPERIENCE WITH CONCRETE PAVEMENT VIBRATORS IN KANSAS

THREE TYPES OF VIBRATORS WERE USED ON THE DIFFERENT PROJECTS STUDIED HERE. A FRONT SCREED VIBRATOR WAS USED ON ONE PROJECT, A VIBRATING PAN ON ANOTHER, AND THE VIBRATING TUBE ON FIVE PROJECTS. IN ADDITION TO STUDY OF THE PROJECTS UPON WHICH VIBRATION WAS USED, NEARBY PROJECTS USING THE SAME AGGREGATES AND CEMENTS WERE STUDIED IN AN EFFORT TO DETERMINE THE EFFECTS PRODUCED BY VIBRATION. A FAIR DEGREE OF SATISFACTION IS OBTAINED BY USING VIBRATORS. ALTHOUGH GAINS IN SLAB QUALITY HAVE NOT BEEN AS GREAT AS IT IS POSSIBLE TO OBTAIN, ONLY EXPERIENCE CAN BRING ABOUT HIGH EFFICIENCY. THE STATEMENT THAT THE HIGHER THE FREQUENCY, WITH PROPER AMPLITUDE, THE BETTER THE RESULTS, IS FOUND TRUE IN KANSAS AS IN OTHER PLACES. IT IS BELIEVED ALSO THAT THE MORE INTERNALLY A VIBRATOR MAY BE MADE TO WORK, THE MORE FAVORABLE THE RESULT. /AUTHOR/
