COUNTY HIGHWAY ASSET MANAGEMENT FOR ELECTED OFFICIALS

Transcription

1 COUNTY HIGHWAY ASSET MANAGEMENT FOR ELECTED OFFICIALS Richard Domonkos, Indiana LTAP Pat Conner, Indiana LTAP November 29 th 2017 Indiana s Internal Improvements Act of 1836 The law addressed issues of canals, roads and new railroad technologies. The1836 law was also notable for establishing early policy for roads in Indiana. The Federal-Aid Highway Act of 1916 Provided the mechanism and financial incentive to the states to organize and plan for establishing and maintaining state highway systems. The Indiana General Assembly responded by establishing a system of market roads as the model for the statewide network. (Challenged in court) 1919 General Assembly rewrote the law, establishing the Indiana Highway Commission Intermodal Surface Transportation Efficiency Act (ISTEA). Now, all modes of transportation would be represented in an attempt to achieve a more integrated approach to transportation. 1

2 Milestones in Indiana transportation Establish the county unit Indiana s Transportation History Gravel Road Law. Established Free plank or gravel Roads Old wood plank and gravel were maintained by residents along a county or township road. These laws retained a link with the past by carrying forward criteria for width, right of way, eminent domain. The 1989 recodification of these laws into Titles 8 and 36. County Unit Law of It established the county as the local government agency with exclusive responsibility for county roads, leading to the idea of the County Unit. The commissioner districts trace their existence to the older system of identifying the roads for which individual commissioners were responsible. Location: Johnson County State Road 144, 8/10 mile southeast of State Road 135. What were we tasked to do? 1. Maintain road surface 2. Maintain drainage 3. Right of way and surveying 4. Roadside Mowing 5. Covered Bridges 2

3 Why Asset Management How did you learn how to manage your roads? Passed down from years of experience This is the way it has always been done Learn from suppliers and material experts Did anyone give you a manual on how to do it Why Asset Management Is that way of doing business still working today? Are you getting better results or falling behind Older methods are being replace by safer more efficient materials or equipment How do you measure if your getting the best bang for your buck

4 Are you going to leave things better then you found it Who here constructed a new a road this year How long until you will rebuild It Will it last that long Don t care - you will be retired by then I can't change the direction of the wind, but I can adjust my sails to always reach my destination.

5 What is transportation asset management Ask 10 people, get no definitive answer Each agency can differ in practice and scope Traditionally tied to pavements A TAM network can comprise bridges, signs, culverts, guardrail, fleet, etc. Balancing agency goals through asset management 2017 Applied Pavement Technology, Inc. At the most basic level asset management is a way to meet the goals of good ownership, effective management, and responsible stewardship.

6 How can Asset Management help? Develop an inventory and rate the condition it is in Determine what level of service is needed Balances funding vs risks Defines the cost to achieve your desired level of service Identifies your treatment options and opportunities Demonstrates what the consequences are if repairs aren t made. (CDP, RSL, ESL) If we are always reacting to conditions we are not managing the asset the asset is managing us! How does this apply to local agency transportation Map 21: A strategic and systematic process of operating, maintaining, and improving physical assets, with a focus on engineering and economic analysis based upon quality information, to identify a structured sequence of maintenance, preservation, repair, rehabilitation, and replacement actions that will achieve and sustain a desired state of good repair over the lifecycle of the assets at minimum practical cost 6

11 Applying The Right Fix In the Right Place At the Right Time 11

12 Questions to Understand Pavement Management How long will the pavement likely last What takes away from the life of the pavement Are there treatments that can restore life to the pavement Are there options to salvage or rehabilitate part of the pavement to retain value At what point is replacement necessary By definition, an asset has value. When there is no longer any value associated with an asset, the asset then becomes a liability Local Agency Guidelines for Developing an Asset Management Plan and Process May 2011 CDP - Critical Distress Point The CDP is the point when pavement distress changes from needing preventive maintenance to needing structural improvement (PASER rating 4) RSL - Remaining Service Life RSL is the time in years from the present until the pavement reaches the CDP DSL Design Service Life DSL is the design life of the pavement to the CDP (On day 1 it should equal RSL) ESL Extended Service Life ESL is the time in years added to the current RSL based on the type of fix used. It does not represent the longevity of the treatment 12

18 NCPP Quick Network Health Check Most Basic Service Cycle How many lane miles in your road network? How many lane miles of work each year? (Rehab and reconstruction only) NCPP Quick Network Health Check Most Basic Service Cycle Divide Lane Miles in your road network By Lane Miles of Work Each Year = Years to Reconstruct the Entire Network Compare to Life of Pavement 18

19 NCPP Quick Network Health Check 850 centerline miles x 2 = 1700 lane miles 1700 lane miles / 30 lane miles of reconstruction = 57 years to reconstruct entire network (1959) Or 114 lane miles of reconstruction each year If an asphalt pavement last 20 years and that 15 years is in good or fair condition or CDP = 42 Divide 42 years in poor condition /57 years until we replace it, now we can assume 74% of the life of that pavement was in poor condition NCPP Quick Network Health Check Calculate: Subtract annual loss of RSL Every year, every lane mile looses at least 1 year of RSL Add ESL gained from treatment Are you gaining ground or losing ground?

24 Questions? 24

25 25

26 Fills crack with fiber reinforced asphalt or rubberized asphalt Seals pavement from water and debris Can Last 3-5 years Used for discrete cracks under ¾ wide 26

27 Derived from very specific crude oil source A rejuvenator changes the chemistry of the (aged) binder and restores the plasticity to the pavement from the top down. Should reapply every 5 7 years Extends the (RSL) remaining service life Recommend for PASER

28 Gravel Base Sand Sub Base Native Soil (sub grade) 28

29 Asphalt emulsion surface coating Lasts 1 to 3 years Can not fill larger than hairline crack Use for good to very good pavements, preventative treatment Can be used over chip seals Slows pavement oxidation and binder hardening Minor sealant 29

30 Gravel Base Sand Sub Base Native Soil (sub grade) Asphalt 30

31 Asphalt Asphalt 31

32 Liquid asphalt followed by aggregate chips Single or double application Seals pavement from water and debris Increases surface friction Non-structural, no rut filling capacity Lasts 3 to 7 years 32

33 Gravel Base Sand Sub Base Native Soil (sub grade) Asphalt emulsion, fine aggregate and mineral filler Seals pavement from water and debris Seals small cracks Non structural Lasts 4 to 7 years 33

34 Polymer modified asphalt emulsion, aggregate and mineral filler Seals pavement from water and debris Non structural, but fills ruts corrects pavement slope Can be applied with fiber reinforcement Can last 5 to 8 years 34

35 Chip seal (Single) followed by a Slurry or Micro-surface Seals pavement from water and debris Increases surface friction Non-structural, minor rut filling capacity Lasts 8 to 11 years 35

36 Asphalt Gravel Base Sand Sub Base Native Soil (sub grade) Hot mix asphalt layer 3/4-1 thick per lift Can be use in conjunction with milling Can correct surface imperfections Increases surface friction Can add structure to pavement Lasts 6 to 12 years or more (many variables) 36

37 MILL AND OVERLAY 37

38 38

39 Mill up to 4 of existing pavement We need to do something more than patching, milling, and resurfacing Where does patching begin and end? Minimize reflective cracking in new surface layers 39

40 Pulverize distressed asphalt surface and mix with base Can add structure to pavement Primarily for rural roads (no curbs) Close to a reconstructed pavement Can add Calcium Chloride, Asphalt or Cement to add strength 40

41 Thin concrete overlay over asphalt Bonded or unbonded Hard armoring Needs joints every 4 to 6 feet square Great for rut resistance 41

42 Removing pavement to base or sub base Opportunity to correct geometric problems Utilities should be upgraded Curb and gutter upgrades possible Can add fabric reinforcement to sub grade at this time Reset to PASER 10 Most costly option total dollars and life / dollar 42
