2.0 PRINCIPLES OF PAVEMENT MANAGEMENT <br />2.1. Foreword <br />This section covers the basics of pavement management, discussing its purpose of as well as best <br />practices for M&R planning as they relate to the lifecycle of a pavement. It explains how these concepts <br />interact within the Lucity pavement management system that was implemented and will provide <br />context for the findings and recommendations within the report. <br />2.2. Pavement Management Principles <br />Pavement management is the process of assessing, prioritizing, and preserving or rehabilitating <br />pavements through a logical system that attempts to use available funds in the most cost-effective <br />manner possible. It is generally an iterative process that grows in accuracy as more data becomes <br />available to better refine prediction models. Figure 3 illustrates that, typically, pavements start <br />deteriorating rapidly once they hit a specific threshold. A nominal investment in cheaper surface <br />treatments at 40% lifespan is much more cost-effective than deferring maintenance until heavier <br />overlays or possibly reconstruction is required just a few years later. Streets that are repaired while in <br />good condition will have an extended lifetime and will cost less over their lifetime than those left to <br />deteriorate to a poor condition. Without an adequate routine pavement maintenance program, streets <br />will require more frequent reconstruction, thereby requiring significantly greater funding. <br />C <br />0 <br />0 <br />0 <br />U <br />N <br />a <br />a <br />a f"IN <br />Figure 3 - Pavement Deterioration and Life Cycle Costs <br />IMS Pavement Management Report Louisville, CO 2022 Page 14 <br />
