Factorial analysis identified the significance of several factors, developed regression models, and explored how variations in specifications led to additional incentive or disincentive pay. The equations may allow contractors and transportation agencies to plan as-built or job mix formula requirements based on incentive/disincentive risk. Approximately 92% of the surface lift rutting and 63% of the binder lift rutting data indicate no difference in pay as a result of discrepancy between predictive model and quality-related specification software-measured pay factors. Observations and recommendations for implementation and further study are presented in this paper.

Prithvi S. Kandhal and Rajib B. Mallick were the investigators on the project. It is published in this Circular because Transportation Research Board Committee A2D03, Characteristics of Bituminous-Aggregate Combinations to Meet Surface Requirements, reviewed the information and determined it provides up-to-date information on the use of opengraded friction courses (OGFC) for applications where providing a high level of surface friction is important for the safety of the motoring public. The committee recommended wide distribution of this information by TRB. This Circular describes the current state-of-the-practice and should be of interest to pavement designers and others responsible for selecting the materials to be used in particular roadway applications.
