CONSTRUCTION CONTROL OF RIGID PAVEMENT ROUGHNESS

PAVING PROCEDURES WERE MONITORED AND PERFORMANCE SURVEYED FOR 5 YEARS ON 108 PORTLAND CEMENT CONCRETE PAVEMENT PROJECTS TO DETERMINE THE FACTORS AFFECTING AS-BUILT SURFACE ROUGHNESS. THE CALIFORNIA PROFILOGRAPH WAS REPORTED EARLIER IN THIS INVESTIGATION TO BE A FAST, ACCURATE, AND REPRODUCIBLE METHOD OF MEASURING ROUGHNESS WITHIN A FEW HOURS AFTER PAVING. BY CONTRAST, CONSCIENTIOUS INSPECTION WITH A 10-FT STRAIGHT EDGE AND CORRECTION OF OUT-OF-TOLERANCE BUMPS DURING CONSTRUCTION DO NOT ASSURE SMOOTH-RIDING PAVEMENT. SLIP-FORM PAVING GENERALLY PRODUCES A MUCH SMOOTHER SURFACE THAN PAVING WITH CONVENTIONAL FIXED SIDE-FORMS. ALTHOUGH GOOD RESULTS CAN BE ACHIEVED BY EITHER METHOD, NEITHER ASSURES SMOOTHNESS. AMONG THE FACTORS FOUND TO AFFECT THE RESULTS FOR SIDE-FORM PAVEMENT ARE PAVING MACHINE BACKUP, PAN FLOATS, NUMBER OF SCREEDS, NIGHT JOINTS, PAVING EQUIPMENT CONDITION, AND PAVEMENT ALIGNMENT AND CROSS-SLOPE. FOR SLIP-FORM PAVING, THE MOST IMPORTANT ARE CONDITION OF THE FINE GRADE AND SUBGRADE, MESH PLACEMENT, NIGHT JOINTS, AND CHANGES IN CONCRETE SLUP. THE CLARY SCREED ALSO SHOWS PROMISE AS A MEANS OF REDUCING PAVEMENT ROUGHNESS WITH SLIP-FORM PAVING. GENERAL REQUIREMENTS FOR A SPECIFICATION TO ASSURE CONSTRUCTION OF SMOOTH PAVEMENT ARE ALSO DISCUSSED.
