Standard Test Method for Measuring the Longitudinal Profile of Traveled Surfaces

Importancia y uso:

5.1 For inertial profiler technology, measuring vehicular traveled surfaces using an instrumented vehicle with a fluctuating inertial reference elevation provides a satisfactory method for acquiring profile elevation measurements (1).

5.2 The profile data can be processed to produce, by simulation, the outputs of other devices. This can be done in real time or can be computed as a post-process. Some of the devices that can be simulated include road meters (2), various straightedge devices (3), profilographs (4), as well as pavers and grinders. Caution should be taken regarding the nonlinear phase shifts inherent in the measurements of the above simulated devices. Comparisons of various equipment and their profile computer programs are referenced (5, 6) .

5.3 The raw data or the profile data can also be recorded later for data processing and analysis and by more complex data processing procedures.
