Pavement Management

 Road network is City’s most valuable resource

 Valued at over $400,000,000.00

 Data-based decision making and trend analysis

factor heavily into the process, and can improve efficiency and efficacy

 3,418 street sections (~650 Lane Miles)

 2965 Sections (~580 LM) – Concrete (84%)  453 Sections (~70 LM) – Asphalt (16%)

Pavement Management

 City developed a Strategic Plan in 2017

 E.vii. – Raise the Pavement Condition Index (PCI) rating

• f the O’Fallon City streets such that no more than 10%
• f the roadways are rated as less than 75.

Recommend a strategy for upgrading and maintaining the City’s most valuable asset.

 E.xi. – Design a program that will replace concrete

slabs on a 30-year rotation (7,000 slabs annually), crack seal on a 5-year cycle (1.2M feet of cracks annually) and overlay asphalt on a 12-year cycle (72,300 square yards annually) by increasing funding.

Pavement Management

 City Staff estimate that $5M per year is needed

• ver the next five (5) years to achieve the strategic

goals, with increases in funding in the following years

 City Staff have presented several times in regards

to opportunities for increased funding:

 Use Tax, ½ cent sales tax, Street Light Fees, Recouping

Property Tax, Etc.

2017 Concrete Program

 Total Funding - $3.992 M  City Council approved three (3) different types of

repairs for concrete streets

 Removal of partial-depth asphalt joint replacement

(Mill and Fill)

 Clearing the backlog of open Work Orders (WO)  Concrete streets that have the lowest PCI ranking in the

City (Low PCI)

2017 Concrete Program

 Removal of partial-depth asphalt joint replacement

(Mill and Fill)

 Six (6) subdivisions cleared of PDAJ repairs, replaced

with new concrete slabs ($750K)

 Clearing the backlog of open Work Orders (WO)

 In collaboration with Streets Dept., reduced WOs from

283 to 19 upon completion ($2.25M)

 Concrete streets that have the lowest PCI ranking in

the City (Low PCI)

 Repaired the 20 lowest rated concrete streets in the

City ($1M)

2017 Concrete Program

 Fixed issues on over 350 street sections throughout

the City

 Replaced nearly 3,000 concrete slabs (1.4% of

total slabs in the City)

 Replaced 62,600 Sq. Yds. Of 7” Concrete  Replaced 5,400 Sq. Yds. Of 8” Concrete

 Replaced 420 Ft. of Concrete Curb Ramp  Installed 970 Ft. of Underdrains  Completed ahead of schedule

2017 Asphalt Program

 No funding was allotted for this program in 2017.  No asphalt streets were repaired.

2017 Crack Seal Program

 Sealing 13 Residential Subdivisions (all roads)  Sealing 24 Individual Streets  Approx. 31 miles of roadway will receive Crack

Sealing

 Approx. 162,000 ft. of roadway will receive Crack

Sealing

 Anticipated completion of project by end of June

2018 Concrete Program

 Types of Street Repairs

 Mill/Fill Segments  Low PCI Segments  Combination of Repairs

 Focused on slab removal  Most efficient when doing lots of work in an area

2018 Concrete Program

 Scenario #1 – M&F

2018 Concrete Program

 Scenario #2 – Low PCI

13% of concrete sections remain rated below 75

2018 Concrete Program

 Scenario #3

 Combination of M&F and Low PCI  $1.5M = ~1100 concrete slabs  Staff would need guidance on City Council’s preferred

allocation percentages (i.e. 50% M&F, 50% PCI, etc.)

2018 Concrete Program

 Staff Recommendation

 Scenario #2  Has more impact in terms of overall street ratings, in

keeping with strategic plan initiatives

 Utilize the Streets Dept. to systematically eliminate the

partial-depth asphalt joints (Mill & Fill) over a number

• f years

2018 Asphalt Program

 Types of Street Repairs

 Full Depth Repairs (Base Failure)  2” Overlay  Rejuvenator / Surface Treatment

 Lots of options in this area  Most efficient when doing lots of work in an area

2018 Asphalt Program

2018 Concrete Program

 Staff Recommendation

 90% Funding towards FDR / 2” Overlay  10% Funding towards Rejuvenation/Surface Treatment  Allows staff to address the worst roads, while keeping

newly replaced roads in good condition

 Most efficient use of funding with regard to asphalt

road repairs, per industry experts

2018 Crack Seal Program

 Working on a definite direction for this program  Completing one (1) Ward per year, to comply with the

strategic plan initiative

 Ward 1 – 72.5 CLM  Ward 2 – 52.2 CLM  Ward 3 – 64.5 CLM  Ward 4 – 53.6 CLM  Ward 5 – 68.7 CLM

 Avg. Cost

 $3,000/CLM – residential streets  $6,000/CLM – collector roads  $12,000/CLM – major arterials

Next Steps

 Presentation of the 2017 O’Fallon Pavement

Manual to City Council (2/22)

 Utilizing PAVER software for project forecasting and

planning

 Developing systematic approach for

planning/execution of O’Fallon Annual Programs
