Terms of Service & Engineering Disclaimer
1. Acceptance of Terms
By accessing, browsing, or using RoadBaseCalculator.com ("the Website" or "the Service"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please discontinue using the calculators and guides immediately.
2. Civil Engineering & Estimation Disclaimer (Critical Notice)
The calculators, formulas, density values, compaction ratios, and lift schedules provided on this Website are designed exclusively for preliminary estimating, planning, and educational purposes.
- Geotechnical Variability: Native subgrade soils (clays, silts, sands) vary significantly in bearing capacity (CBR) and moisture sensitivity. A site with saturated high-plasticity clay requires specialized subgrade stabilization and geotextile filtration beyond generic guidelines.
- Quarry Material Variances: Quarry rock deposits, natural moisture contents, and crushed particle gradations vary across pits and geographic regions. Stated densities (e.g., 135 lb/ft³ for Crusher Run) represent theoretical Proctor maximums and may differ from your certified quarry scale receipt.
- Not a Substitute for Professional Geotechnical Engineering: Using this Website does not establish an engineer-client relationship. You must verify all structural depths, truck axle weight allowances, and purchasing volumes with a licensed Professional Engineer (PE), registered civil engineer, or local certified aggregate supplier before placing commercial purchase orders or beginning excavation.
3. Limitation of Liability
To the maximum extent permitted by applicable law, Road Base Calculator, its creators, authors, and contributors shall not be liable for any direct, indirect, incidental, consequential, special, or exemplary damages arising out of:
- Material shortages, delivery abort fees, or material surpluses resulting from calculator outputs;
- Pavement, driveway, or foundation cracking, settlement, rutting, or subgrade structural failure;
- Property damage caused by haul trucks, vibratory rollers, or excavation machinery;
- Any reliance placed on calculations, tables, or written guides without independent local verification.
4. Intellectual Property & Permitted Use
All interactive calculator source code, interactive visualizers, SVG illustrations, and written articles are the proprietary intellectual property of Road Base Calculator and protected by copyright laws.
You are granted a personal, non-exclusive, non-transferable license to use the calculators for personal estimating and contractor bidding purposes. You may not scrape, frame, redistribute, reverse-engineer, or mirror the calculators on third-party commercial domains without prior written authorization.
5. Third-Party Standards & Attributions
References to ASTM, AASHTO, TxDOT, Caltrans, VDOT, CDOT, and ICPI standards are included for identification, comparative technical reference, and educational purposes only.
