Efficient Transportation Contributes To:

Quality of life Environmental value Economic growth

2015 Construction Program

Continued from 2014

Preservation Modernizatio

n Expansion

$60M continued from 2014

River Road and Roberts Road: New Roundabout

Peterson Road, US 45 to w of IL 83: Add lanes

Rollins Road at IL 83: Grade separation

Wadsworth Road at IL 131: Reconstruct and widen

$75M in new projects

24 projects, 11 contain non-motorized travel improvements, (bike paths, or adding bike friendly lanes)

Two significant expansion projects: Peterson Road Corridor Washington Street Thoroughfare

LCDOT’s management philosophy sets system priorities:

1. Preservation2. Modernization3. Expansion

Priority One: Preservation

10

Tools in the Toolbox: ARGUS

Pavement Management Software

Asset Inventories

Unit cost information

Industry standards

22%Preservation projects: approximately

of program

LCDOT Uses ARGUS Pavement Management System

11

To make cost-effective decisions:

Where repairs are needed

What repair strategies to use

When the repairs should be done

Using these program components:

County highway database

Automated pavement testing

Repair strategies with costs

Pavement aging prediction

Optimization program

Laser surface testing

Dynaflect

Pavement Aging Prediction Costs

12

Repairs Made at the Best Time to Maximize Return

LCDOT ARGUS results

13

Implemented in 1986

Condition rating has improved from 68 to 81

Backlog/failing pavement areareduced from 55% to 8%

Current Pavement Rating is 81(Good)

14

Good (80 – 100)Sections may require crack sealing or a thin overlay. These sections do not require immediate attention. Pavement in this category is generally less than 12 years old.

Satisfactory (70-79)Sections may require resurfacing or other rehabilitation in the near future. Pavement is generally 12-14 years old.

Failing (60-69)Will require some type of improvement in the near future to preserve the usability of the surface and avoid the need for reconstruction. This is pavement that is approaching the end of its useable life.

Backlog (10-59)May require surface and base course reconstruction to restore roadway serviceability. Some may require total reconstruction, including reconstruction of the subgrade. Pavement in this category is generally more than 15 years old.

ARGUS Summary

16

Pavement Management System does…

Assess the present condition of the system

Estimate future road conditions

Identify and rank road projects

Maximize the condition of the system within the given budget

Pavement Management System does not… Replace professional judgment

Provide certain detailed project-specific information

Evaluate storm sewer and other roadway assets

Level of Service Data

26

Traffic engineers use LOS

data to evaluate how a given

intersection is functioning.

Better levels of service mean

fewer delays at the

intersection

C or better meets driver

expectations

LCDOT uses Synchro traffic

analysis software to evaluate

intersection operations and

performance

right now in planning that can’t even be programmed for construction in this 5-year plan because of available funding.
