This report describes a methodology for determining the optimal timing for the application of preventive maintenance treatments to flexible and rigid pavements. The methodology is also presented in the form of a macro-driven Microsoft (registered trademark) Excel Visual Basic Application--designated OPTime--available to users by accessing the National Cooperative Highway Research Program (NCHRP) website (http://trb.org/news/blurb_detail.asp?id=4306). The methodology is based on the analysis of performance and cost data and applies to any of the treatments and application methods that are used by highway agencies. A plan for constructing and monitoring experimental test sections is also provided to assist highway agencies in collecting the necessary data if such data are not readily available. The report is a useful resource for state and local highway agency personnel and others involved in pavement maintenance and preservation.
