Development of a Construction Control Profilograph
Due to an increasing awareness of the importance of the pavement roughness at the time of construction, a profilograph for measuring construction roughness was developed and obtained. The profilograph used featured (1) twelve averaging wheels arranged in a systematic method, (2) equally spaced averaging wheels, both longitudinally and transversely, (3) a recorder especially designed to emit both a graphical profile and a digital roughness index number, and (4) outrigger wheels allowing the profilograph to be towed to various testing locations without disassembly. Studies of the influence of texture in pavement roughness were made leading to a modification in the profilograph recording mechanism for a filter band. A 0.1-inch filter band was utilized to reduce the influence of texture in pavement roughness measurements. Based on field studies with the 0.1-inch filter band a 'profile index' of 26 inches per mile was determined and a suggested specification was written employing a maximum 'profile index' and a maximum 'single peak deviation'.
