3. 2013-2018 Five Year Highway Improvement Program LCDOT’s management philosophy sets system priorities: 1. Preservation 2. Modernization 3. Expansion 3

4. Priority One: Preservation Developing a set of projects ARGUS Pavement Management Software Keeping tabs on the system Asset Inventories $1.6 billion to build 4

5. Developing the Project Set ARGUS Pavement Management System Today is an introduction to ARGUS 5

6. 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

7. Pavement Management System Components: County highway database Automated pavement testing Repair strategies with costs Pavement aging prediction Optimization program 7

8. County Highway Database Contains information on: Surface type Surface width Section area Traffic volumes Percentage of trucks 8

9. Automated Pavement Testing About 864 lane miles in system County is divided into quadrants One quadrant is tested each year Entire county is covered in four years 9

10. Automated Pavement Testing First: Laser Road Surface Tester (RST) measures… Cracking Rutting Ride quality 10

11. Automated Pavement Testing Second: Dynaflect deflection tester measures strength and condition of … Pavement Subgrade 11

12. Repair Strategies and Costs Two Groups of Roadway Priorities: (starting with 2010-2014 program analysis) Four lane roads - 53 miles Two lane roads - 247 miles 12

13. Repair Strategies and Costs Microsurfacing Five resurfacing strategies Three “3R” strategies Three reconstruction strategies Associated per-square-yard costs 13

14. Pavement Aging Prediction Costs 14

15. ARGUS Summary 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 15

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

17. LCDOT ARGUS results Started in 1986 System condition has improved from a rating of 68 to 81 (on 100 scale) Area of backlog and failing pavement has been reduced from 55% to 13% 17

20. Definitions of Pavement Condition 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. 20
