National Pavement Infrastructure • 160,000 miles in NHS Pavement
Network • 500+ million tons of Hot Mix
Asphalt produced annually • 25+ million cubic yards of
concrete produced annually
• Nearly 50 yr old empirical approach to pavement design
• Pavement design lives are not being achieved in many cases
• Work zones are a serious impact to mobility
• Material price increases • Competing Priorities

Planning & Prioritizing Work
• We Can’t Do Everything • Focus on “First Things First” • Drive Priorities from Focus Area Needs • Priority Assessment
– Customer Needs/Input – Level of Effort/Complexity – Benefit/Effectiveness
