Pros and cons
Asphalt Calculator
- Density transparency: every result prints the exact density value used, making the output auditable and useful for cross-checking a supplier's quote.
- Gmm support: accepts a maximum theoretical density value from a job mix formula and applies a 94% compaction factor, a level of technical depth rare in free browser calculators.
- Multi-area sessions: stack multiple shapes with independent depths in one calculation, covering L-shaped lots or projects with thicker apron sections without separate runs.
- No labor or installation cost output: the calculator stops at material tons and an optional plant price per ton, so it cannot produce a full project budget. Competing tools like asphaltcalc.org include real-time cost ranges that cover more of the project cost picture.
- Web-only with no saved sessions: there is no account system, so a contractor cannot save a job, share a link with a client, or return to a previous estimate. The 'Copy link' feature encodes inputs in the URL but requires the user to manage that link manually.
- No structural thickness guidance built into the calculator itself: depth recommendations from the Colorado Asphalt Pavement Association appear in editorial text below the tool, not as an integrated input wizard, so a first-time user can easily enter the wrong depth and get a confidently wrong tonnage.
Notion AI
- AI tools operate directly inside Notion pages, databases, and connected apps
- Business plan ($20/user/month) includes full AI suite: Agent, Meeting Notes, Enterprise Search, Research Mode
- Custom Agents let you automate multi-step workflows using triggers and run on-demand
- Free and Plus only offer limited trial access - full AI requires Business or Enterprise
- AI usage is credit-based and can lead to unpredictable costs, especially with Custom Agents
- Not useful if your data lives outside Notion - standalone AI tools may serve better
Our verdict
Asphalt Calculator verdict
Asphalt Calculator is the right pick for a contractor or homeowner who needs a transparent, formula-driven tonnage estimate without creating an account or paying anything. It exposes its density assumptions and rolldown math in a way most competing free calculators do not, which makes it genuinely useful for checking a supplier's quote. It does not do pavement design, structural thickness recommendations, or labor cost estimation, so anyone who needs a full project budget rather than a material quantity should look elsewhere.

Notion AI is best for teams whose data already lives in Notion and who want AI that writes, searches, and automates inside that workspace. It falls short if your content lives outside Notion or if you need predictable AI usage costs. If you’re looking for a standalone AI chatbot or cheaper per-use pricing, consider ChatGPT or Claude instead.
