The Profilograph: A Rotating Device that Creates ...
The Profilograph is a bizarre device created by Chicago artist Pablo Garcia based on a series of four books written in 1528 by German artist Albrecht Dürer that examine the geometry of the male profile through carefully documented illustrations. The device transforms a series of Dürer's drawings into a contiguous 3D extrusion that rotates on a circular spindle causing a shadow that morphs between .
Profiling | definition of profiling by Medical dictionary
With incomparable accuracy and control, MonacoPROFILER is the premier solution for Hexachrome profiling," said Andrew Hatkoff, senior director of Pantone's Electronic Color Systems Division.
COMPUTER SIMULATION AND VALIDATION OF CALIFORNIA ...
The California Type Profilograph is presently used by many state transportation agencies to evaluate and accept the ride quality of new Portland Cement Concrete pavements. Although the Profilograph equipment is normally owned by the paving contractor, the state highway agency is often interested in making the same measurements with their own equipment.
ASTM E1274 Standard Test Method for Measuring Pavement ...
This test method covers the measurement of pavement roughness using an articulated multiwheeled profilograph at least 23 ft (7 m) long (Fig. 1 is typical). This test method utilizes a surface record made by moving the profilograph longitudinally over the pavement at less than 3 mph (5 km/hr).
What is Road Pavement Profilometer? (The Manufacturer)
Road pavement profilometer (aka profilograph, as used in the famous AASHO Road Test) uses a distance measuring laser (suspended approximately 30 cm from the pavement) in combination with an odometer and an inertial unit (normally an accelerometer to detect vehicle movement in the vertical plane) that establishes a moving reference plane to which the laser distances are integrated.
ASTME1274
FIG. 1 Typical Profilograph This test method utilizes a surface record made by moving the profilograph longitudinally over the pavement at less than 3 mph (5 km/hr). The record is analyzed to determine the rate of roughness and to identify bumps that exceed a specified threshold.

UTAH DEPARTMENT OF TRANSPORTATION
PROFILOGRAPH AND PAVEMENT SMOOTHNESS Smooth pavement is the number one public demand. Also, pavement with a smooth surface is proven to last longer. The California Type Profilograph, shown in Figure 1, is a primary tool used to measure the pavement smoothness in Utah. It consists of a rigid 25 ft. long frame, supported at each end by a wheel
Evaluation of Relationship Between Profilograph and ...
The relationship between the profilograph profile index (PI) and the international roughness index (IRI) is evaluated. To accomplish this evaluation, profile data taken on 48 overlaid test sections were used in profilograph simulations to predict the profilograph response to the measured profiles.
Survey Profilograph Design | Synergy Positioning Systems
Survey Profilograph Design. Synergy's Survey Profilograph vehicle provides an accurate high speed representation of the longitudinal and cross sectional change in grade for pavements of any type. Not only is the system is perfect for checking the geometric shape of an existing surface but it also calculates the current ride qualities too.
