Selecting the appropriate pavement preventive maintenance treatment, together with determining the optimal timing of its placement, is critical to lowering agency costs effectively and improving pavement performance. The objective is to develop a methodology for treatment selection and its optimal timing based on matter element analysis (MEA). MEA methodology aims to solve problems with contradictions, and incompatibilities and pavement preventive maintenance decision making fit into this domain. Using data sets consisting of Specific Pavement Study-3 pavement sections from the Long-Term Pavement Performance database, statistical performance deterioration models for the do-nothing and posttreatment scenarios for four typical preventive treatments (chip seal, slurry seal, crack seal, and thin overlay) are developed. The models capture variations in environment, traffic level, structural condition, and pavement age. The performance indicators are the international roughness index, rutting, and friction number. The posttreatment benefit for each individual indicator and the cost of the treatment are calculated at multiple trial timing scenarios. Integrating the calculated costs and benefits in the MEA as a matter element, the optimal timing for each treatment is determined on the basis of the correlation degree of the matter elements. Consequently, the corresponding benefits and costs at the optimal timing scenarios constitute another matter element. Following the same matter element–based transformation procedure, the appropriate maintenance treatment is selected. A case study is presented to illustrate the proposed procedure. The proposed methodology should be useful both to agencies that already have a preventive maintenance program and to those considering implementation of such a program.
