DEVELOPMENT OF COMPOSITE QUALITY MEASURES

Statistical construction specifications based on multiple quality characteristics frequently use pay equations that include a separate term for each of the quality characteristics so that the resultant pay adjustment is a function of the combined effect of all quality measures. An alternate method that can be used to accomplish the same purpose is to base the pay equation on a single quality measure that is a composite of the individual quality measures. The latter approach, because it keys the various decision-making steps to a single performance indicator, simplifies the procedure and offers several practical advantages. It is believed that this approach makes significant strides toward the ultimate goal of developing quality assurance procedures that are at the same time technically sound, fair and effective, and easy to understand and apply. Examples of a two-variable case for hot-mix asphalt pavement and a general three-variable case are presented.
