THE CONSTRUCTION OF A CONCRETE PAVEMENT HAS BEEN COMPARED TO AN ASSEMBLY-LINE OPERATION. BUT HERE THE OPERATION MUST BE CARRIED ON OUT-OF-DOORS, THE PRODUCT IS STATIONARY AND THE MACHINES PROGRESS DURING THE PAVING OPERATION. CHANGES IN WEATHER CONDITIONS, CONCRETE CHARACTERISTICS AND PAVEMENT PROFILE MAY REQUIRE CHANGES IN THE ADJUSTMENT OF THE EQUIPMENT AND ITS OPERATION TO SECURE PROPER CONSTRUCTION. ANY DISCUSSION OF THE PROPER ADJUSTMENT OF THE MECHANICAL EQUIPMENT REQUIRES A BRIEF OUTLINE OF THE FUNCTION AND OPERATION OF EACH MACHINE. FOR THEM TO PROPERLY SHAPE AND CONSOLIDATE THE CONCRETE INTO A PAVEMENT SLAB THEY MUST OPERATE AT THE PROPER TIME IN RESPECT TO PAVEMENT PLACEMENT, AT THE PROPER SPEED AND THEY MUST BE IN PROPER ADJUSTMENT. FULL ADVANTAGE CANNOT BE TAKEN OF THE CAPABILITIES OF THE EQUIPMENT WITHOUT A KNOWLEDGE OF THE ADJUSTMENTS THAT CAN BE MADE IN THE VARIOUS MACHINES AND THE EFFECT OF THESE ADJUSTMENTS ON THE FINISHING PROCEDURES. IN SOME CASES, PIECES OF EQUIPMENT HAVING SIMILAR FUNCTIONS ARE MADE BY SEVERAL DIFFERENT MANUFACTURERS. THE DETAILS OF ADJUSTMENT MAY DIFFER BETWEEN MANFACTURERS AND BETWEEN OLDER AND NEWER MODELS OF THE SAME MANUFACTURER, BUT IN GENERAL THE ADJUSTMENTS FOLLOW ABOUT THE SAME PATTERN. ALTHOUGH IT IS NOT THE DUTY OF THE RESIDENT ENGINEER AND INSPECTOR TO MAKE THE ADJUSTMENTS IN ANY PIECE OF EQUIPMENT THEY SHOULD BE ABLE TO DIRECT THE CONTRACTOR'S PERSONNEL IN MAKING THEM. TO ASSIST THEM IN THIS IMPORTANT DUTY IS THE PURPOSE OF THIS PAPER. /AUTHOR/
