The problem of selecting suitable segments for treatment in a pavement management system is complex because pavements exhibit considerable spatial variability in performance. This paper presents an algorithm for grouping small segments with uniform performance into large segments that are appropriate for a construction project. The algorithm works across lanes and along the traveled way and uses multiple years of predicted treatments rather than raw information on condition. A series of subprocedures is used to do the grouping, which is centered on a statistical approach to joining adjacent segments. A final treatment that is based on the treatments that were merged into the group is recommended, although the larger segments can also be used in the pavement management system, with aggregated performance, for optimization and project selection.
