More Than Just a Project – We Build Relationships

About Calculator Asphalt

Welcome to, your ultimate destination for expert insights on asphalt pavements. As a licensed civil engineer with over 20 years of experience specializing in asphalt materials, specifications, and construction, I created this website as an educational resource for both professionals and homeowners.

Our mission is to simplify asphalt calculations and provide the practical tools and knowledge needed to execute your projects with maximum quality and efficiency.

My Background

My path in the asphalt construction business began over two decades ago when I joined my father’s small paving company focused on parking lots and driveways. I learned quickly that success in asphalt base building relies on having the right equipment fleet and skilled people who know how to use it efficiently.

In the first few years, we struggled with managing our equipment spreads across projects and finding high-quality equipment operators. I remember our first major commercial site – it required a large asphalt base build. We had secured the bid mainly because of price, yet on day one I realized we were underprepared when our lone paver struggled to keep pace. We finished 45 days late and 20% over budget.

After that wake-up call, I made it my mission to optimize our equipment selection and spreads based on each new project’s unique scope. I also doubled down on hiring and training the most qualified equipment operators possible. Over the next decade, through meticulous coordination of crew sizes, machinery, timings, and personnel assignments across 20 major asphalt base builds, I’m proud to say we consistently delivered exceptional quality on schedule.

A standout example was a 250,000 square foot retail base job with tricky logistics and terrain challenges. By deploying a customized fleet plan with our most skilled foreman leading the equipment team, we completed the high quality build 12 days ahead of schedule. Word of our attention to detail and capability to handle complex projects started spreading, leading us to become a leading civil works contractor in the region.

Looking back over 150 completed asphalt bases big and small, it’s clear that taking the time to matchmake the right machinery to each operation with a talented crew who knows their job is what separates the success stories from the problem sites. My 20 year journey shows why optimized coordination between equipment spreads and qualified operators makes all the difference in asphalt base construction.

Making Asphalt Calculations Simple

On large paving jobs like parking lots, roads, and highways, estimating required asphalt quantities can be incredibly complex. Small project volumes, mix variations, grade adjustments, waste factors, compaction – the list of considerations is endless. Improper estimates lead to either costly shortages or wasteful overordering.

At, our goal is to demystify these calculations with user-friendly yet powerful asphalt estimation tools. With simple inputs like your project dimensions, materials selected, and specifications, our custom calculators determine the precise asphalt tonnage, volume and coverage area needed.

We handle all the complicated formulas and conversions so you have confidence in your paving estimates. Detailed measurement records are built-in to document your inputs and assumptions. Reports can be exported for project stakeholders and suppliers.

As an engineer, accuracy and transparency are top priorities in developing these calculators. You can trust our results.
