Can a resurfaced driveway handle the weight of an RV or camper parked on it in Ottawa?
Whether a resurfaced driveway can handle RV weight depends entirely on the condition of the existing base underneath and the weight of your specific RV. Most asphalt overlays are only 50mm thick and rely completely on the structural integrity of what's beneath.
Understanding RV Weight and Driveway Loading
A typical travel trailer weighs 3,000 to 8,000 pounds loaded, while Class A motorhomes can exceed 30,000 pounds. More critical than total weight is the axle loading — how that weight distributes through the tires to the driveway surface. A heavy RV concentrates enormous point loads through relatively small tire contact patches, creating far more stress per square foot than regular passenger vehicles.
In Ottawa's extreme climate, this concentrated loading becomes even more problematic. When asphalt softens during summer heat (35+ degrees Celsius), heavy RV loads can cause rutting and deformation that becomes permanent once the asphalt cools. During freeze-thaw cycles, any existing base weakness beneath the overlay will telegraph through as cracking or settling under the RV's weight.
When Resurfacing Can Handle RV Weight
An asphalt overlay can support RV parking if the existing base is structurally sound — meaning the original driveway had proper Granular B sub-base (300mm+) and Granular A base (150mm+) that remains stable and well-compacted. If your existing driveway shows no significant cracking, settling, or edge deterioration, and the overlay was applied as a maintenance measure rather than to hide structural problems, it may handle moderate RV weight.
However, most Ottawa driveways built before 2000 have minimal base preparation by today's standards. Builder-grade driveways from the 1970s-1990s often have only 150-200mm of total base depth, which is insufficient for heavy vehicle loading even when new.
Red Flags That Indicate Base Problems
Never park an RV on a resurfaced driveway if the original surface showed alligator cracking, potholes, edge cracking, or settling. These are signs of base failure, and a thin overlay cannot fix structural problems. The RV weight will accelerate the underlying failure, causing the new surface to crack and rut within one season.
Similarly, if your driveway was resurfaced to "make it look better" rather than as routine maintenance on a structurally sound surface, it's likely hiding problems that RV weight will expose.
Ottawa-Specific Considerations
Ottawa's clay soils in areas like Barrhaven, Orleans, and Gloucester create additional challenges. Clay expands and contracts dramatically with moisture changes, and RV weight can compress clay subgrade that wasn't properly stabilized during original construction. The deep frost line (1.2-1.5 metres) means any base deficiencies become more severe during freeze-thaw cycles.
Practical Assessment Steps
Walk your driveway and look for any soft spots, minor cracking, or slight depressions where the overlay meets the original surface. These indicate base movement that will worsen under RV loading. Check the driveway edges — if they're crumbling or unsupported, RV weight near the edges will cause edge failure.
Consider the RV's wheelbase and turning radius. Tight maneuvering concentrates loads and creates shear forces that stress the surface differently than straight-line parking.
When to Hire a Pro
Have a paving contractor assess your specific situation before parking a heavy RV. They can determine if the existing base is adequate and whether additional structural work is needed. For RVs over 15,000 pounds, consider having the driveway cored to verify actual base depth and condition.
If your resurfaced driveway cannot handle RV weight, options include building a separate reinforced parking pad with proper base depth for heavy vehicles, or full driveway reconstruction with adequate structural design.
