2012-2017 Five Year Highway Improvement Program

Management philosophy sets system priorities:

1. Preservation

2. Modernization

3. Expansion

Priority One: PreservationDeveloping a set of projects

ARGUS Pavement Management Software

Keeping tabs on the system

Asset Inventories

$1.6 billion to build

Developing the Project SetARGUS Pavement Management System……

……Today is an introduction to ARGUS

5

Pavement Management Goal

Make cost effective decisions

For given 5 year budget levels:

Where repairs are needed

What repair strategies to use

When the repairs should be done

6

Pavement ManagementSystem Components:

County highway database

Automated pavement testing

Repair strategies with costs

Pavement aging prediction

Optimization program

7

County Highway DatabaseContains information on…

Surface type

Surface width

Section area

Traffic volumes

Percentage of trucks

8

Automated Pavement Testing

About 855 lane miles in system

County is divided into quadrants

One quadrant is tested each year

Entire county is covered in four years

Repair Strategies and CostsTwo Groups of Roadway Priorities:

(starting with 2010-2014 program analysis)

Four lane roads - 53 miles

Two lane roads - 244 miles

12

Repair Strategies and Costs

Four resurfacing strategies

Three “3R” strategies

Three reconstruction strategies

Associated per-square-yard costs

ARGUS SummaryPavement 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

ARGUS Summary …Pavement Management System does not…

Replace professional judgment

Provide certain detailed project-specific

information

LCDOT ARGUS results

Started in 1986

System condition has improved from a rating of

68 to 79 (on 100 scale)

Area of backlog and failing pavement has been

reduced from 55% to 9%

Definitions of Pavement ConditionGood (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.
