Profilograph A device used to measure smoothness by measuring the deviations of a pavement surface using a mid-point measuring wheel from the reference established by a set of wheels (6 for a California-type) at either end of the device. Profilograph Index (PrI) A smoothness index that is computed from a profilograph trace.the Profilograph, and the procedure used to locate individual high points in excess of specification limits. 2. Operation of the California Type Profilograph 2.1 Apparatus 2.1.1 The California Type Profilograph consists of a frame 7.6 m (25 ft) in length supported upon wheels at either end. The profile is recorded from the vertical movement of
Read MoreA CTD or Sonde is an oceanography instrument used to measure the conductivity, temperature, and pressure of seawater (the D stands for "depth," which is closely related to pressure). The reason to measure conductivity is that it can be used to determine the salinity.. The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette.英语单词大全为您提供profilograph是什么意思,profilograph例句,profilograph在线翻译,profilograph中文意思,profilograph的意思,profilograph的翻译,profilograph的解释,profilograph的发音,profilograph的同义词,profilograph的反义词,profilograph的例句,profilograph的相关词组,profilograph意思是什么,profilograph怎么翻译,单词profilograph是什么 ...

According to the Federal Highway Administration and the National Asphalt Pavement Association (NAPA), smooth roads last longer, are safer and save money because they require less maintenance.The SSI CS8500 Profilograph is the most trustworthy and perhaps the most widely used surface profiling device in the world. In 2004 SSI acquired the McCracken profilograph operation from the Besser Company (Sioux City, IA), making SSI the only supplier of California style profilographs.

These vertical deviations are recorded on a continuousthe profilograph may be obtained by the districts from the Transportation Laboratory. Near the center of the scale is an opaque band 5 mm wide extending the entire length. On either side of this band are scribed lines 2 mm apart and parallel to the opaque band. These

Read MoreThe profilograph is a manually propelled device that uses rolling wheels. Profilographs have limited and erratic frequency response to the pavement roughness. The inertial profiler uses laser sensors and can travel at highway speed. Inertial profilers provide more consistent results.Pavement Smoothness (sometimes termed roughness – the opposite of smoothness) is ultimately a measure of the drivers' comfort. It is commonly estimated using a pavement profile (a measure of minute elevation changes in the pavement surface). Pavement profiles can be visualized as imaginary lines "drawn" along the surfaces of the pavement.
