Editorial & Corrections Policy
1. Our Editorial Mission
Road Base Calculator was created to bring clarity, mathematical rigor, and engineering transparency to aggregate estimation. Traditional online calculators often rely on flat, generic multiplication factors that lead to massive under-ordering or expensive material surpluses.
Our mission is to provide accurate, multi-factor calculations that clearly distinguish between compacted in-place dry density, quarry scale delivery weight, and loose haul truck capacity.
2. Geotechnical Standards & Fact-Checking
Every figure, grain-size gradation curve, and compaction ratio published on our website is cross-referenced against established public-domain civil engineering specifications:
ASTM C33 / C136 (Sieve Analysis & Concrete Aggregates), ASTM D2940 (Graded Aggregate Bases), ASTM D698 (Standard Proctor), and ASTM D1557 (Modified Proctor Compaction).
AASHTO M147 (Aggregate and Soil-Aggregate Subbase, Base and Surface Courses) and AASHTO M288 (Geotextiles for Highway Applications).
TxDOT Item 247 (Texas Flexible Base & Caliche), Caltrans Section 26 (Class 2 Aggregate Base), VDOT Section 208 (21A/21B Stone), and CDOT Section 703 (Class 6 Base).
Interlocking Concrete Pavement Institute (ICPI) Tech Spec 2 guidelines for interlocking concrete pavement base and bedding layers.
3. Editorial Independence & Commercial Non-Bias
We maintain strict editorial independence. We do not accept paid material placements, sponsored quarry listings, or undisclosed commercial endorsements.
When our calculators recommend specific aggregate grades (e.g., TxDOT Grade 1 vs. Grade 4), recommendations are determined strictly by engineering performance, structural stability, and permeability criteria.
4. AI Use & Automated Tools Disclosure
We believe in full transparency regarding technology:
- Calculation Engines: All mathematical algorithms, equations, and unit conversions are custom-coded deterministic programs tested against manual civil engineering hand calculations.
- Assisted Drafting: Large language models and automated synthesis tools may be used to assist in organizing outlines, formatting tables, and drafting explanatory prose.
- Human Verification: All technical specifications, grain-size sieve percentages, optimum moisture targets, and density values are verified against published engineering literature and state DOT manuals before publication.
5. Corrections Policy & Error Reporting
Accuracy is the foundation of trust. If you notice a typo, an outdated DOT specification reference, a mathematical error, or an aggregate density discrepancy for a regional quarry deposit, we actively welcome your input.
How to Submit a Correction:
- Email our technical desk directly at: estimator@roadbasecalculator.com.
- Include the page URL, the specific figure or text in question, and a reference to the relevant standard, quarry scale sheet, or state DOT manual.
Our team reviews reported corrections within 3 business days. When substantive technical errors are identified, we correct the formula or text and log the modification.
