Michigan Local Technical Assistance Program Roads as an Asset
6
Michigan Local Technical Assistance Program Window of Opportunity Time Poor Preventative Maintenance Heavy Maintenance Light Rehabilitation Heavy Rehabilitation Asset Replacement Condition Rating CDP Excellent
7
Michigan Local Technical Assistance Program Managing Physical Assets the Nuts & Bolts Steps 1. Inventory 2. Condition (rating) 3. Predicting future condition 4. Managing network
8
Michigan Local Technical Assistance Program You can’t manage what you don’t know you own 8 1.Inventory – What do I own?
9
PASER Pavement Condition Rating PASER – Pavement Surface Evaluation and Rating Visual survey—based on sound engineering principles Measure of surface distress Scale of 1-10

Michigan Local Technical Assistance Program Predicting the Future Rules of thumb Past experience Professional opinion Model historical rating data
11
Michigan Local Technical Assistance Program Future Condition What will happen tomorrow?

Michigan Local Technical Assistance Program 4. Network Level Measure Historical distribution NCPP Network Health National Center for Pavement Preservation Management System - RoadSoft Service Cycle
13
Michigan Local Technical Assistance Program Network Level Vs. Project Level Project: Moving pieces Network: Winning game
14
Michigan Local Technical Assistance Program Service Cycle How big is the network? How much of the network do I do work on? How long will it take to “touch” the entire network? Is this longer than the expected life of my pavement? EXAMPLE 500 lane mile road network Do 10 lane miles of work each year Takes 500/10 = 50 years to touch all of the network Asphalt pavement only last 15 years

Michigan Local Technical Assistance Program NCPP Network Condition Health # Of Lane Miles in your network Same number of RSL lost each year How it works... Programmed Activity (reconstruction, chip seal, etc.) Fix Cost (per lane mile) Extended Service Life (ESL) # of Lane Miles Fixed Result Lane Mile Years per Fix Total for Entire Network
