CONSTRUCTION CONTROL OF RIGID PAVEMENT ROUGHNESS

RESULTS OF A 2-YEAR STUDY OF CAUSE-EFFECT RELATIONSHIPS INVOLVED IN ROUGHNESS OF CONCRETE PAVEMENTS ARE REPORTED. DATA WERE DERIVED BOTH FROM ANALOG TRACES OBTAINED IN EACH WHEELPATH WITHIN HOURS AFTER CONCRETE PLACEMENT ON RANDOMLY SELECTED PAVEMENTS, AND FROM QUALITATIVE OBSERVATIONS OF PAVING METHODS. SAMPLED CONSTRUCTION CONSISTED OF 184 SECTIONS OF ONE-AND TWO-LANE PAVEMENT BUILT UNDER 62 DIFFERENT CONTRACTS WITH SEVEN DIFFERENT FORM-TYPE FINISHING MACHINES AND THREE DIFFERENT SLIP-FORM PAVERS. STATISTICAL ANALYSIS WAS HELD TO A MINIMUM BY UNCONTROLLED INTERACTIONS, BUT FIVE FACTORS WERE FOUND TO BE COMMON AND OUTSTANDINGLY SIGNIFICANT IN RELATION TO ROUGHNESS THROUGHOUT THE CONTRACTS STUDIED: BACKING UP OF THE LAST FINISHING MACHINE, ABSENCE OF A FLOAT, USE OF LESS THAN THREE SCREEDS, USE OF A CROWN SECTION AS COMPARED TO A UNIFORMLY SLOPING SECTION, AND LANE-AT-A-TIME PAVING. /AUTHOR/
