ASTM E1927-98 (R2018) PDF Download

ASTM E1927-98 (R2018) is a standard guide that describes a procedure for conducting subjective pavement ride quality ratings. The purpose of this standard is to provide a method for obtaining numerical ride quality ratings for a range of highway pavement sections based on a standard numerical scale. These ratings are closely correlated to the collective qualitative judgments of the total user community, reflecting their satisfaction with the condition of the pavements.

The standard emphasizes the importance of obtaining statistically representative data by observing certain sampling theory principles. This includes the size and selection of the rating panel, which should be members of the user community, and the method of quantifying their judgments. The selection of sample pavement sections is also crucial to ensure that the data obtained accurately represents the average ride quality judgments of the total highway user community.

The resulting ride quality data obtained through this standard can be used for various purposes. One important use is to test deterministic functions of physical parameters of the pavement samples, such as the longitudinal profile, in order to estimate subjective ride quality judgments. This data can also be a valuable resource for monitoring the performance of highway pavement construction, maintenance, and repair operations.
