FIVE YEAR HIGHWAY IMPROVEMENT PROGRAM 3 LCDOT’s management philosophy sets system priorities: 1.Preservation 2.Modernization 3.Expansion

PRIORITY ONE: PRESERVATION 4 Developing a set of projects ARGUS Pavement Management Software Keeping tabs on the system Asset Inventories $1.6 billion to build

DEVELOPING THE PROJECT SET 5 ARGUS Pavement Management System Today is an overview of ARGUS

PAVEMENT MANAGEMENT GOAL: 6 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

PAVEMENT MANAGEMENT SYSTEM COMPONENTS: 7 County highway database Automated pavement testing Repair strategies with costs Pavement aging prediction Optimization program

COUNTY HIGHWAY DATABASE 8 Contains information on: Surface type Surface width Section area Traffic volumes Percentage of trucks

AUTOMATED PAVEMENT TESTING 9 About 870 lane miles in system County is divided into quadrants One quadrant is tested each year Entire county is covered in four years

AUTOMATED PAVEMENT TESTING 10 First: Laser Road Surface Tester (RST) measures… Cracking Rutting Ride quality

AUTOMATED PAVEMENT TESTING 11 Second: Dynaflect deflection tester measures strength and condition of… Pavement Subgrade

REPAIR STRATEGIES AND COSTS 12 Two Groups of Roadway Priorities: (starting with program analysis) Four lane roads: 53 miles Two lane roads: 247 miles

REPAIR STRATEGIES AND COSTS 13 Microsurfacing Five resurfacing strategies Three “3R” strategies Three reconstruction strategies Associated per-square-yard costs

PAVEMENT AGING PREDICTION COSTS 14

ARGUS SUMMARY 15 does… 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

ARGUS SUMMARY 16 does not… Pavement Management System does not… Replace professional judgment Provide certain detailed project-specific information

LCDOT ARGUS RESULTS 17 Started in 1986 System condition has improved from a rating of 68 to 84 (on 100 scale) Area of backlog and failing pavement has been reduced from 55% to 9%

2014 – 2019 PROPOSED HIGHWAY IMPROVEMENT PROGRAM 18 The following charts to appear in Section 2 Preservation Projects

TRAFFIC VOLUMES 19

DEFINITIONS OF PAVEMENT CONDITION 20 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 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.
