Getting to Know Your Asphalt: HMA, Cold Patch, RAP & More

Think all blacktop is the same? Think again! Choosing the right asphalt mix for your paving project makes a huge difference – affecting how long it lasts, how well it performs, what it costs, and even its impact on the environment. Getting familiar with the main options – like Hot Mix Asphalt (HMA), Cold Patch, and Recycled Asphalt Pavement (RAP) – helps you make smarter choices and talk confidently with your contractor.

Think of this page as your hub for understanding asphalt materials. We've put together guides that break down what each type is, where it shines, and how they differ. Dive in!

Need a quick pothole fix? This guide covers Cold Patch (CMA) – how it works, easy DIY steps, common slip-ups, and the big catch: why it's usually just a temporary band-aid.

Why Materials Matter for Your Project Math

Keep in mind: the type of asphalt you pick directly influences your project calculations, especially how much tonnage you'll need. Why? It mostly comes down to density.

Denser mixes like HMA mean you need less volume to hit the same weight (tonnage) compared to fluffier stuff like Cold Patch or a RAP Base.
Nailing the density is key for ordering the right amount. Want the full scoop on how density plays into the math? Check our Tonnage Calculation Guide.
Psst... Our Advanced Tonnage Calculator lets you pick specific materials or even plug in your own density numbers.
