Synthesis for Best Practices for Preventive Maintenance Preparatory Work

The synthesis study shall focus on pavement preparatory work performed before preventive maintenance (PM) surfacing contracts with the goal of answering, “What work needs to be performed to the roadway before a new surface is placed?” Preparatory work performed by in-house maintenance forces or maintenance contracts may include crack sealing, fog seal, repairs, milling, and level-up and should be performed well in advance of the PM contract. Both flexible and rigid pavements may require work in advance of a PM contract. Seal coats or thin overlays are typical PM surfacing projects. The synthesis shall investigate best practices, factors that affect materials selected, factors that affect repair decisions, timing of preparatory work and the effects of the repair procedures and materials on the life of the new surface based on the preparatory work performed.
