Pavement Design Calculator Skill

Purpose

The Pavement Design Calculator Skill designs flexible and rigid pavements using AASHTO 93, MEPDG, and other established methods including overlay design and life-cycle cost analysis.

Capabilities

• Flexible pavement design (AASHTO 93, MEPDG)
• Rigid pavement design
• Overlay design
• Traffic loading analysis (ESALs)
• Material characterization
• Life-cycle cost analysis
• Structural number calculation
