<b>🛣️ Mechanistic-Empirical Pavement Design Tool</b><br>
</h1>
Welcome to the **Mechanistic-Empirical Pavement Design Tool for Highways and Airports**! This application is designed to assist engineers and researchers in designing and evaluating pavement structures based on traffic, material, and environmental data.
**The app is available at:** [https://pavement-design-app.streamlit.app/](https://pavement-design-app.streamlit.app/)
---
## 🚀 Features
- **Input Data**: Upload or manually input traffic, climate, subgrade, and material data.
- **Pavement Design**: Define pavement layers, material properties, and costs.
- **Simulation**: Analyze pavement performance under various conditions.
- **Lifecycle Cost Analysis (LCCA)**: Evaluate the economic efficiency of pavement designs.
- **Results Visualization**: View performance predictions, cost analysis, and pavement design details with interactive charts.
- **Report Generation**: Create and download detailed reports in PDF format.
---
## 🛠️ Installation
```bash
git clone https://github.com/GitsSaikat/Pavement-App.git
cd pavement-design-tool
pip install -r requirements.txt
streamlit run app.py
```
## Project Structure
- `app.py`: Main Streamlit application file.
- `Pavement.jpg`: Image used in the application.
- `src/`: Source code directory.
- `models.py`: Contains data model classes.
- `performance.py`: Includes functions for pavement performance simulation.
- `lcca.py`: Functions for life cycle cost analysis.
- `reporting.py`: Functions for report generation.
- `design.py`: Functions for designing the pavement structure.
- `utils/`: Contains utility scripts.
- `helpers.py`: Helper functions for file reading and saving.
- `logger.py`: Setting up logging.
- `README.md`: This file, contains project documentation
## Usage
**Input Data**: Either upload your data using an Excel file or manually enter all the required data to proceed with the design.
- **Excel File**: Make sure your Excel file contains sheets named 'Traffic', 'Climate', 'Subgrade' and 'Materials' with the correct columns. See instructions on the page.
- **Manual Entry**: Alternatively, fill the forms with the respective data fields, in which the comma separated values are supported in axle loads inputs.
**Design Pavement**: Define the pavement layers by entering the number of layers and then configure the type and thickness of each one.
**Run Simulation**: Set initial costs, maintenance costs, discount rate, and analysis period to run the pavement simulation and LCCA.
**View Results**: Analyze the simulation results, lifecycle cost, and pavement design details through tables and charts.
**Generate Report**: Create a comprehensive PDF report of your analysis.
