A COMPARISON OF BRIDGE DECK ROUGHNESS' 1963 AND 1965

THE RIDING QUALITY OF BRIDGE DECKS, CONSTRUCTED BEFORE AND AFTER ADOPTION OF THE SPECIAL PROVISIONS FOR FINISHING BRIDGE DECKS, ARE COMPARED. THIS INCLUDES 34 BRIDGE DECKS CONSTRUCTED PRIOR TO THE ISSUANCE OF THE SPECIAL PROVISIONS, AND 25 BRIDGE DECKS CONSTRUCTED /AFTER APRIL 1, 1964/ AFTER ISSUANCE. FOR PURPOSES OF DATA ANALYSIS, THESE BRIDGE DECKS WERE DIVIDED INTO THREE GROUPS IN ACCORDANCE WITH METHOD OF SCREEDING, NAMELY, LONGITUDINAL WITH MECHANICAL OSCILLATING SCREED, TRANSVERSE WITH MECHANICAL OSCILLATING SCREED AND TRANSVERSE WITH MANUAL VIBRATORY SCREED. ALL ROUGHNESS DATA WERE OBTAINED WITH A BPR-TYPE ROUGHOMETER. CONCLUSIONS DRAWN WERE' /1/ BRIDGE DECKS CONSTRUCTED SUBSEQUENT TO THE 1964 SPECIAL PROVISIONS HAD APPRECIABLY BETTER RIDING QUALITIES THAN THOSE CONSTRUCTED PRIOR TO 1964, /2/ LONGITUDINAL SCREEDING PRODUCED THE SMOOTHER BRIDGE DECKS, AND /3/ CONSIDERABLE VARIATION IN THE ROUGHNESS OF BRIDGE DECKS SCREEDED BY THE SAME METHOD SUGGESTS THAT CONTROL AND QUALITY OF WORKMANSHIP AND EQUIPMENT MUST BE MAINTAINED AT HIGH STANDARDS TO OBTAIN RESULTS CAPABLE OF BEING ACHIEVED.
