SURFACE IRREGULARITY DATA FOR RECENT MAJOR ROAD WORKS' SPECIFICATIONS AND TOLERANCES

MEASUREMENTS WERE MADE WITH A MULTI-WHEELED PROFILOMETER OR A BUMP INTEGRATOR ON A CONSIDERABLE NUMBER OF RECENT MAJOR ROAD WORKS, IN ORDER THAT THE STANDARDS OF SURFACE FINISH AND THE VARIABILITY BETWEEN AND WITHIN INDIVIDUAL PROJECTS COULD BE ASCERTAINED AND COMPARED WITH THE CURRENT REQUIREMENTS OF SPECIFICATIONS. STANDARDS WERE FOUND TO VARY WIDELY BUT ON NEARLY ALL THE ROADS AN APPRECIABLE PROPORTION OF THE WHOLE SURFACE HAD A FINISH BETTER THAN THE 1/8-INCH STANDARD. IT IS CONSIDERED THAT SUPERVISING ENGINEERS SHOULD AIM PRIMARILY AT MINIMIZING THE VARIABILITY OF SURFACE FINISH IN ORDER TO IMPROVE OVERALL RESULTS. THIS IN TURN IMPLIES EFFICIENT AND ADEQUATE CONTROL OF ALL MATERIALS AND PROCESSES IN CONSTRUCTION. /RRL/
