Description of ASTM-E1489 2019ASTM E1489-08-Reapproved2019Historical Standard: Standard Practice for Computing Ride Number of Roads from Longitudinal Profile Measurements Made by an Inertial Profile Measuring DeviceASTM E1489Scope 1.1 This practice covers the mathematical processing of longitudinal profile measurements to produce an estimate of subjective ride quality, termed Ride Number (RN). 1.2 The intent of this practice is to provide the highway community a standard practice for the computing and reporting of an estimate of subjective ride quality for highway pavements. 1.3 This practice is based on an algorithm developed in National Cooperative Highway Research Project (NCHRP) 1–23 (1, 2),2 two Ohio Department of Transportation ride quality research projects (3, 4), and work presented in Refs (5, 6). 1.4 The computed estimate of subjective ride quality produced by this practice was named Ride Number (RN) in NCHRP Research Project 1–23 (1, 2) to differentiate it from other measures of ride quality computed from longitudinal profile. Eq 1 of 8.2 represents the mathematical definition of Ride Number. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
