About Bilal Khalid
I am Bilal Khalid, a software developer and the creator of asphaltcalculator.cloud. I hold a Bachelor of Science in Computer Science (BSCS) and a Master of Philosophy (M.Phil.) in Computer Science, and I build precision-driven calculators for contractors, engineers and homeowners.
For the past 5 years I have worked in computer applications, building fast, easy-to-use web tools and turning construction formulas into calculators that give clear, checkable answers.
Experience and Expertise
- M.Phil. in Computer Science: advanced study of software structures and algorithms.
- BSCS: a foundation in software engineering, database design and application logic.
- 5+ years in computer applications: designing web utility tools and making sure the numbers they output are correct.
- Paving and construction tools: asphalt tonnage, driveway cost, overlay, bitumen and base calculators built around United States units and typical prices.
How the calculators are checked
Each calculator uses a standard, published formula, such as tons = area x thickness x density, and the formula is shown on the page. Before a page goes live, the tool is tested against worked examples that are calculated by hand, and its figures are compared with industry references such as the National Asphalt Pavement Association and the Asphalt Institute.
Prices on the site are planning ranges, not quotes. Always confirm quantities and costs with your plant or contractor before ordering.
