Terms of Use

By accessing or using pavements.design (the "Site"), including any calculators, equations, tools, documentation, or related materials (collectively, the "Tools"), you acknowledge that you have read, understood, and agree to be bound by these Terms of Use. If you do not agree, you should not use the Site.

pavements.design is a collaborative, educational project intended to:

• Document and share concrete pavement design and analysis frameworks
• Provide transparent implementations of established calculation methodologies
• Support education and technical advancement in concrete pavement design and construction

The Site is provided free of charge and is not a commercial engineering service.

The Site and its Tools:

• Do not constitute engineering services
• Do not create an engineer–client relationship
• Do not replace professional judgment
• Are not a substitute for applicable codes, standards, or project-specific engineering

All calculations, frameworks, and outputs are provided for informational and educational purposes only. The Tools may contain computational errors, omissions, implementation differences from published methodologies, or limitations that affect results. Outputs should always be independently verified before being used in design, construction, or engineering decision-making.

While we make a good-faith effort to:

• Accurately implement published methodologies
• Verify equations and calculations
• Review and test outputs

The Site and Tools are provided "as is" and "as available." We make no representations or warranties of any kind, express or implied, including but not limited to:

• Accuracy
• Completeness
• Reliability
• Fitness for a particular purpose
• Compliance with local codes or project requirements

Errors, omissions, or computational inaccuracies may exist.

To the fullest extent permitted by law, pavements.design, its contributors, and collaborators shall not be liable for any direct, indirect, incidental, consequential, special, exemplary, or punitive damages arising out of or relating to:

• Use of the Site
• Reliance on calculations or outputs
• Interpretation of information
• Design decisions based on Site content
• Construction outcomes or project performance

You assume full responsibility for all use of information obtained from the Site. Use of the Site and Tools is at the user's sole risk.

Users are responsible for:

• Verifying all inputs and outputs
• Confirming unit consistency
• Applying appropriate load factors, safety factors, and design criteria
• Ensuring compliance with governing codes and standards
• Exercising independent professional judgment

Engineering design is context-specific. No calculator can replace competent technical evaluation.

Unless otherwise noted, content on the Site — including code, text, graphics, and documentation — is the property of pavements.design contributors. Published methodologies referenced (e.g., StreetPave framework concepts) remain the intellectual property of their respective organizations. Users may reference and cite materials for educational or professional purposes, but may not misrepresent the origin of the Tools or content.

We reserve the right to modify, update, or discontinue any portion of the Site at any time without notice. Methodologies and implementations may evolve as the project develops.

These Terms shall be governed by and interpreted in accordance with the laws of the State of Georgia, United States, without regard to conflict of law principles.
