3 Agenda Introductions & Welcome 10:05-10:15 How to Rate Your Roads 10:15-10:50 What to Do with Your Ratings 10:50-11:10 & How GIS Can Help Lunch 11:10-11:30 Extending the Life of Your Pavement 11:30-12:00 Through Proper Maintenance & Forecasting

4 Meet Your Speakers Ken Ward Maria Kealey Arlyn Kurth Mike Michalski

5 Pavement Management Pavement Ratings Pavement Rater Training Road Network Valuation Long-Term Road Program Forecasting

6 Good Rating Practices When to Do Your Ratings Spring or Fall Sunny Days After a Rainfall (Not During) Verify Your Mileage Certification Entries

7 Where to Spend Your Time New Roads (9-10 PASER, PCI) Drive-By Will Pick Up Major Issues Fair Roads (5-8 PASER, PCI) Walking Inspection (2-5 min/segment) Poor Roads (1-4 PASER) Drive-By is Sufficient Poor Roads (0-55 PCI) Walking Inspection (2-5 min/segment+)

8 Know Your Roads Super Pave Mix Designs Brittle Raveling Last 10 Years 2017 Mix Designs

9 Know Your Roads Loading Types & Locations Weight Limits Pavement Cores & Soil Borings

10 How to Rate Your Roads Maria Kealey Arlyn Kurth

11 Types of Pavement Distress Surface Defects Surface Deformation Cracking Potholes/Patching

12 Surface Defects Raveling Small aggregate particles have worn away exposing tops of large aggregate. Erosion further exposes large aggregate.

13 Surface Defects Polishing & Flushing Polishing Worn aggregate needs repair Flushing Dark patches show where asphalt has worked to the surface

14 Surface Deformation Rutting Even slight rutting is evident after a rain. Severe rutting over 2 caused by poor mix design.

15 Pavement Cracking Transverse Longitudinal Block Alligator

16 Pavement Cracking Transverse Cracks

17 Pavement Cracking Transverse Cracks

18 Pavement Cracking Longitudinal Cracks First stage of wheelpath cracking caused by heavy traffic loads. Longitudinal Cracks

19 Pavement Cracking Block Cracks Large blocks, approximately 10 across. Intermediate-size block cracking, 1-5 across with open cracks Extensive block cracking in an irregular pattern

20 Pavement Cracking Alligator Cracks Alligator crack pattern. Tight cracks and one patch.

21 Potholes & Patching

22 Rating 10 & 9 EXCELLENT No Maintenance Required RATING 10 - New construction. RATING 10

23 Rating 10 & 9 EXCELLENT No Maintenance Required RATING 9 - Recent overlay, rural. RATING 9

24 Rating 8 VERY GOOD Little or No Maintenance Required RATING 8 RATING 8 - All cracks are tight or sealed.

25 Rating 7 & 6 GOOD Routine Sealing Recommended / Consider Preservative Treatment RATING 7 RATING 7 - Tight and sealed transverse and longitudinal cracks. Maintain crack sealing program.

26 Rating 7 & 6 GOOD Routine Sealing Recommended / Consider Preservative Treatment RATING 6 - Slight surface raveling with tight cracks, less than 10 apart. RATING 6

27 Rating 5 & 4 GOOD Preservative Maintenance Treatment Required / Structural Improvement Required RATING 5 - Moderate to severe raveling in wheel paths. RATING 5

28 Rating 5 & 4 GOOD Preservative Maintenance Treatment Required / Structural Improvement Required RATING 4 - Extensive block cracking. Blocks tight and sound. RATING 4

29 Rating 3 POOR Structural Improvement Required RATING 3 - Many wide and raveled cracks indicate need for milling and overlay. RATING 3

30 Rating 2 VERY POOR Reconstruction Required RATING 2 - Extensive alligator cracking. Pulverize and rebuild. RATING 2

31 Rating 1 FAILED Reconstruction Required RATING 1 - Potholes from frost damage. Reconstruct. RATING 1

32 Tips for Road Rating Two people Items to bring: Map of community PASER manual Rating spreadsheet

33 What to do with Your Ratings & How GIS Can Help Mike Michalski

34 Process the Ratings Entering & Submitting directly into Wisconsin Information System for Local Roads (WISLR) Utilizing GIS application

35 WISLR - Pavement Rating Entry Screen Entering & Submitting directly into WISLR Update & Review Paser Rating for GTA Funding Allocations Pavement Analysis Analysis Budgeting Tool

36 WISLR Pavement Analysis Condition Report

37 WISLR Pavement Analysis Rudimentary Need Analysis

38 WISLR Analysis Budgeting Tool Five Year Budget Plan

39 GIS Application Decisions making becomes better. Improve communication with Board Members and Residents. Better record keeping.

40 GIS Application Decisions making becomes better Assist with prioritizing the roadways Highlights projects that allow for cost sharing between the Utilities and Public Works Departments

41 GIS Application Improve communication with Board Members and Residents Asist in storytelling and understanding situations User access is unlimited

42 GIS Application Better record keeping Keeper of details and important records regarding the changes and status of roadways

43 Extending the Life of Your Pavement Through Proper Maintenance & Forecasting Ken Ward, P.E.

44 Maintenance Strategies to Save Dollars

45 Pavement Life Asphalt Roads Year Minimum with a Goal to Stretch to 30 Years Proper & Timely Maintenance Techniques to Reach 30 Year Target Poor or Little Maintenance Will Reduce Life Span to Less Than 15 Years

46 Maintenance/Reconstruction Cost $$$ Review: Condition of Streets Pavement Life Cycle Excellent Each $1 of renovation cost here Good 40% drop in quality Fair Poor 75% of life 40% drop in quality 12% of life Will cost $6-$10 if delayed to here Very Poor Failed Time

47 Preventative Maintenance Improves & Extends the Functional Life of a Pavement Done Prior to Failure Budget Separately for it

48 Common Causes of a Failure in Asphalt Pavements Inadequate Drainage (Primary Cause) Poor or Improper Maintenance Base Failure Fatigue

49 How Pavements Fail Loading Crack Creation Drainage Poor Drainage Tree Canopy

50 Cost-Effective Maintenance Techniques Crack Sealing & Crack Filling Surface Sealing Curb & Gutter Replacement Drainage Improvements Maintenance Overlays

51 Cost-Effective Maintenance Techniques Crack Sealing Crack Sealing Crack Sealing Crack Sealing

52 Sealant Placement Proper Placement of Sealant

53 Wasted Effort on Sealant Placement

54 Inadequate or Improper Maintenance Keep Water Out of the Road Base Don t Defer Maintenance

55 Pavement Sealing Improves Surface Texture Waterproofs Surface Protects Pavement from Oxidation Seals Small Cracks

56 Types of Pavement Seals Slurry Seal Requires Road Closures (4-6 Hours) Provides Non-Fading Surface Subject to Plow Damage Chip Seal Quick Application Dust & Sweeping Issues Potential Property Damage Claims

57 2 Year Old Slurry Seal Crack Seal Prior to Placement

58 What Does Preventive Maintenance Cost? Crack Sealing or Crack Filling $0.75 to $1.35/L.F. Chip Seal $2.15 to $2.55/S.Y. Slurry Seal $2.35 to $2.75/S.Y. Base Patching $18.50 to $20.00/S.Y. Curb & Gutter replacement $22.00 to $26.00/L.F.

59 What Does Preventive Maintenance Cost? 2 Asphalt Overlay $7.10/S.Y. ($124,000/Mile) 2 Mill and Overlay $9.00/S.Y. ($152,500/Mile) Pulverize and 4 Overlay $16.50/S.Y. ($290,000/mile) Complete Reconstruct Rural $110 to $150/L.F. Complete Reconstruct Urban $225-$325/L.F. Plus Utilities

60 Long-Term Road Program Budget Forecasting

61 Road Program Funding How do you fund your roads? Capital Borrowing Street Funds Storm Water Utility State/Federal Funding Assessments

62 Road Program Funding Short-term maintenance costs Short-term construction costs Long-term maintenance costs Long-term CIP construction costs

63 Keeping Up with Your Roads No Maintenance - Average Road Life of ~15-20 Years 5% of Roads Pulverized/Reconstructed a Year $1.15 Million for 1 Mile (50/50 Urban/Rural) With Maintenance Average Road Life of ~20-30 Years 3.5% of Roads Pulverized/Reconstructed a Year $750,000 for 2/3 Mile (50/50 Urban/Rural)

64 Forecasting for Your Roads Know the Value of Your Road Network Project Out to Your Average Road Life 20 or 30 Year Window Use Your Last Road Improvement as a Guide Track Your Subdivisions Extending Your Roads with Maintenance

65 Planning Your Road Program Know the Value of Your Road Network Fixed Budget vs. Fluctuating Budget Stick to Your Maintenance/Rehab Plan Know What s Coming 5 Years Past Your CIP
