AASHTO R 57-14 (2018) PDF Download

The AASHTO R 57-14 (2018) standard outlines the procedure for operating and calibrating an inertial profiling system. The primary purpose of this standard is to serve as a quality control/quality assurance (QC/QA) test for smoothness specification compliance during paving operations and network-level data collection. It is important to note that this practice is not intended to be a mandatory QA procedure for daily monitoring of paving operations but is rather recommended for use during QC testing when inertial profiling systems are utilized.

The standard establishes guidelines for conducting QC/QA tests using inertial profiling systems and provides instructions for verifying the calibration of such systems. It highlights the importance of accurate and reliable data collection for assessing the smoothness of paved surfaces and emphasizes the relevance of adhering to appropriate quality control measures during paving operations.
