2.3. Pavement Management Program The practical implementation of a pavement management program requires that an agency have an accurate understating of the assets under its management. To fulfill this requirement IMS was contracted by Louisville, CO to conduct a comprehensive pavement condition assessment and pavement management analysis on the City's roadway network. 2.4. Lucity Pavement Management System The City primarily utilizes Lucity for its pavement management program. Lucity will allow the city to catalog, classify, assess, track, and analyze condition data to aid in the processes of budget planning and pavement rehabilitation. More specifically the program will help the City through the process of pavement management by giving structure to the basic information required for a management system: • Pavement Section Inventory • Pavement Deterioration Modeling • Prioritization • Funding Analysis • Inspection Data • Rehabilitation Selections & History • Work Planning • Reporting The following pages will briefly detail the reasoning behind why this information is collected and used within the management program. Pavement Section Inventory An accurate inventory of all City -owned streets is necessary to make any determinations, assumptions, or projections within a management system. The individual attributes about length, width, location, traffic use, surface type, condition, and other factors that may be tracked are all tied back to a single management segment within Lucity and given a unique ID within the program. The attributes stored here determine what types of rehabilitation activities can be applied, how the section is prioritized within the system, and allow for placement and sorting during reporting. Inspection Data Lucity has the ability to use a blended condition index depending on the goals and requirements of the City which allows a custom reporting value to be built that is representative of aspects being considered to rank the condition of a pavement. The inputs for this index rely on inspection data from the field survey. In addition to the data collected for PCI, International Roughness Index (IRI) data was also used in Lucity. Details on the individual components of the inspection are available in section 2.5 Pavement Deterioration Modeling Inspection data by itself is only able to represent conditions at the time of collection. Within Lucity there are customizable curves that predict the rate of pavement deterioration based on a streets functional class, pavement type, and strength rating. The guiding concept is that pavements with like uses and attributes will deteriorate at similar rates. As such, high volume asphalt arterials in already poor conditions would be expected to deteriorate faster and are represented in Figure 5 below with a purple line. On the opposite end of the spectrum, low volume concrete local streets would be expected to deteriorate slowly and are represented with a blue dashed line.
