Estimate the required amount of asphalt material (tons or bags) for your pothole repair based on its shape, dimensions, and material type.
For a circular pothole with a 3 ft diameter and an average depth of 4 inches, using Cold Mix (130 lbs/ft³) with a 10% waste factor:
The Pothole Repair Calculator is a specialized tool designed to provide accurate material estimates for one of the most common pavement maintenance tasks: repairing potholes. It addresses the primary challenge of any repair project—determining exactly how much asphalt material to purchase. By accounting for various shapes (rectangular, circular, and irregular), dimensions, and material types, this calculator delivers precise volume and weight calculations. The key benefit of using the Pothole Repair Calculator is preventing the waste of buying too much material or the frustration of not having enough, saving both time and money on your repair project.
The power of the Pothole Repair Calculator lies in its flexible yet robust calculation engine. Recognizing that potholes are rarely perfect squares, the tool allows users to select the shape that best fits their situation. The logic then applies the correct geometric formula—whether for a rectangle, a circle (cylinder), or a user-defined area—to find the surface area. This is then multiplied by the user-provided average depth to determine the total compacted volume of the repair. From there, the calculator functions identically to a professional asphalt patching estimator, applying the correct density for the selected material (like Hot Mix Asphalt or Cold Patch) to convert the required volume into the total weight needed for the order. This systematic approach ensures a reliable result every time.
More than just a number-cruncher, the Pothole Repair Calculator serves as a practical guide for executing a successful repair. The results are always accompanied by an essential "Application Advisory" if the specified depth exceeds industry standards for a single layer. This critical feature reminds users to apply the material in compacted "lifts" (layers), a professional technique essential for the long-term durability of any deep patch. This advice aligns with standards from transportation authorities and engineering guides, such as those published by the Federal Highway Administration. For a broader understanding of pavement materials, Wikipedia's page on Asphalt Concrete is an excellent technical resource. The Pothole Repair Calculator distills this expert knowledge into easy-to-understand guidance.
Ultimately, the Pothole Repair Calculator empowers you to tackle pavement repairs with confidence. It replaces rough guesswork with a data-driven estimate, allowing for accurate budgeting and efficient material purchasing. By providing clear outputs for both volume and weight, along with vital application tips, the tool ensures you are well-equipped for a professional-quality repair that will stand the test of time.

For an odd-shaped pothole, you can approximate the area. One simple method is to imagine a grid of 1x1 foot squares over the top and count how many squares the pothole mostly fills. Alternatively, measure the longest length and the average width and calculate it as a rectangle, which will provide a safe overestimate.
For most homeowners, bagged Cold Mix Asphalt (often called "cold patch") is the best choice. It's readily available, requires no special heating equipment, and can be applied directly from the bag. Hot Mix Asphalt (HMA) is generally more durable but requires professional installation.
Potholes rarely have a perfectly flat bottom. By measuring the depth in a few different places and using the average, you get a much more accurate estimate of the total volume that needs to be filled compared to just measuring the deepest point.
It is strongly advised not to. For any patching material to bond correctly, the hole must be clean and, most importantly, dry. Water will prevent the asphalt from adhering to the existing pavement and will lead to a failed patch.
