Standard Guide for Conducting Subjective Pavement Ride Quality Ratings

Importancia y uso:

5.1 A primary responsibility of highway agencies is the construction and maintenance of highway pavements in a condition (including ride quality) perceived to be satisfactory by the user community. The ability to quickly, easily, and economically acquire an objective standard numeric (rideability index) that will estimate the current level of satisfaction for lengths of pavement is desirable for determining when an acceptable level of ride quality does not exist and corrective measures are required.

5.1.1 This guide describes a procedure to produce subjectively derived, numerical ride quality ratings for each sample of a broad spectrum of highway pavement sections based on a standard numerical scale (0 to 5, described herein). These rating estimates may be considered to be closely correlated to the collective qualitative judgments of the total related highway user population.

5.1.2 The MPR data set thus obtained can be useful in testing various hypothesized deterministic functions of certain physical parameters of sections of pavement, such as the measured longitudinal profile, as estimators of the ride quality rating the user population might assign to any particular member of the total relevant inventory of highway pavement sections.

5.1.3 Objective, quantitative, easily measurable rideability index data shown to be highly correlated with MPRs are a valuable resource for monitoring the performance of highway pavement construction, maintenance, and repair operations.
