# 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
- Thickness determination

## Usage Guidelines

### When to Use
- Designing new pavements
- Evaluating rehabilitation options
- Analyzing pavement life
- Comparing alternatives

### Prerequisites
- Traffic data available
- Subgrade characterization complete
- Material properties known
- Design period established

### Best Practices
- Use appropriate design method
- Verify traffic projections
- Consider drainage effects
- Evaluate life-cycle costs

## Process Integration

This skill integrates with:
- Pavement Design
