Will my asphalt Ottawa driveway support a moving truck delivery?

Most Ottawa asphalt driveways can support a standard moving truck delivery, but the age, condition, and thickness of your asphalt are critical factors. A typical moving truck (26-foot box truck) weighs 15,000 to 20,000 pounds loaded, which translates to roughly 3,000 to 4,000 pounds per square foot of tire contact area.

Asphalt thickness and base preparation determine load capacity. A properly constructed Ottawa driveway with 100mm (4 inches) of asphalt over a well-compacted granular base can typically handle moving truck loads without damage. However, many residential driveways in Ottawa — particularly those built in the 1980s and 1990s — have only 50-75mm of asphalt, which may be insufficient for heavy truck traffic. Builder-grade driveways in newer subdivisions often use minimum thickness specifications that work fine for cars but can deform under truck loads.

Ottawa's extreme climate adds complexity to load-bearing capacity. During hot summer days (above 30°C), asphalt becomes softer and more susceptible to rutting and deformation under heavy loads. Conversely, in cold weather, brittle asphalt may crack under sudden heavy loads, especially if the base beneath has been compromised by freeze-thaw cycling. The ideal time for heavy truck deliveries on asphalt is during moderate temperatures (15-25°C) when the asphalt maintains both flexibility and strength.

Existing damage significantly reduces load capacity. If your driveway already shows cracking, rutting, or areas where the base has settled, a heavy truck can worsen these problems dramatically. Alligator cracking (interconnected cracks forming a pattern like reptile skin) indicates base failure, and heavy loads will accelerate the deterioration. Edge cracking along the driveway perimeter is particularly vulnerable — truck tires near the edges can cause chunks of asphalt to break away.

Practical steps to protect your driveway: First, assess your driveway's current condition and approximate age. Driveways over 15 years old with visible cracking should be evaluated carefully. Consider having the truck park on the street and using a dolly or hand truck for longer distances, or request that the driver position the truck to distribute weight over the strongest part of your driveway (typically the center, away from edges). If your driveway shows significant wear, you might place plywood sheets under the truck's rear wheels to distribute the load over a larger area.

When to avoid truck access entirely: If your driveway has potholes, significant cracking, soft spots that depress when you walk on them, or areas where water pools regularly, keep heavy trucks off the surface. These are signs of base failure, and truck loads will cause expensive damage that requires full section replacement rather than simple patching.

For driveways in questionable condition or if you're unsure about load capacity, having the moving truck park on the street is the safest approach. The inconvenience of a longer carry is minimal compared to the cost of repairing truck damage to your asphalt.
