THE INFLUENCE OF JOINT WIDTHS AND SPACING ON PAVEMENT RIDING QUALITIES

THE INFLUENCE OF TRANSVERSE JOINT WIDTH AND SPACING ON PAVEMENT RIDING QUALITY WAS INVESTIGATED TO DETERMINE IF IT WAS POSSIBLE TO REDESIGN TRANSVERSE JOINTS, THUS IMPROVING JOINT SEALER PERFORMANCE WITHOUT AFFECTING RIDING QUALITY. DURING A FIELD TEST, PAVEMENT ROUGHNESS AND NOISE LEVELS WERE MEASURED FOR JOINTS FROM 3/8 TO 1 1/2 IN. WIDE, SPACED ON 40 FT. AND ON 60 FT. 10 IN. CENTERS. IT WAS FOUND THAT (1) INCREASE IN ROUGHNESS DUE TO VARYING THE GROOVE WIDTH WAS SMALL, AND DID NOT AFFECT RIDING QUALITY, (2) NO DIFFERENCE IN ROUGHNESS RESULTED FROM REDUCING SPACING BETWEEN JOINTS, AND (3) ALTHOUGH INCREASE IN NOISE LEVEL MEASURED BY SOUND RECORDING EQUIPMENT WAS NEGLIGIBLE, THE HUMAN EAR DEFINITELY DETECTED SOUND CAUSED BY JOINTS OF 7/8 IN. WIDTH OR MORE WHEN SPACED 60 FT. 10 IN. APART, AND OF 5/8 IN. WIDTH OR MORE WHEN SPACED 40 FT. APART. /AUTHOR/
