Here's the uncomfortable math of industrial pavement: one fully loaded tractor-trailer stresses asphalt on the order of thousands of car passes. Pavement engineers measure this in ESALs — equivalent single axle loads — and the takeaway for a warehouse owner is simple: a lot built to a car-parking spec will be destroyed by truck traffic, and no amount of patching will save it.
If you're building or rebuilding pavement for a warehouse, distribution facility, or industrial yard in Metro Atlanta, here's what the specification actually needs to say.
Pavement is a system: subgrade, base, asphalt
Heavy-duty pavement fails from the bottom up, so the spec has to start below the asphalt.
Subgrade. Much of Metro Atlanta sits on Piedmont clay soils, which lose strength when wet and hold water when they get it. Under truck loads, a soft wet subgrade flexes, and flexing is what cracks pavement. A proper industrial job proof-rolls the subgrade — running a loaded truck across it to find soft spots — and fixes what pumps or ruts before anything gets built on top. Stabilization (undercut and replace, or treating the soil) costs real money, but it's the cheapest place in the whole project to prevent failure.
Base. In Georgia the standard is graded aggregate base (GAB), compacted in lifts. Where a car lot might carry 6 inches of GAB, heavy truck areas typically want in the range of 8 to 12 inches, compacted to spec and verified — not just spread and rolled once.
Asphalt. Thickness is the headline number, and it should be specified as *compacted* thickness, in lifts:
- Car parking areas: commonly 2 to 3 inches over a standard base
- Truck routes, drive lanes, loading areas: commonly 4 to 6+ inches, placed as a binder course plus a surface course
- Extreme-duty zones (container yards, heavy equipment storage): thicker sections still — or concrete, honestly, in the worst spots
These are honest industry ranges, not a design for your site — actual thickness comes from your soils, your traffic, and your loads. Anyone quoting a thickness before understanding all three is guessing.
Mix selection matters more than most owners realize
Not all hot-mix asphalt is equal. Georgia paving generally uses Superpave mix designs, and the right choice for industrial work differs from a residential street:
- Binder course: a larger-stone mix deep in the section for structural strength
- Surface course: a tighter mix up top for durability and water resistance
- High-stress zones: stiffer or polymer-modified binders resist rutting and shoving where trucks brake, turn, and idle — Georgia summer pavement temperatures make this a real consideration, since hot asphalt ruts far more easily under slow, heavy wheels
Design around the known failure points
After 15+ years of paving Metro Atlanta commercial properties, we can tell you where industrial lots fail first — and every one of these is predictable at design time:
- Dock approaches, where loaded trailers creep, brake, and sit. Slow and stationary loads are far harder on asphalt than rolling traffic.
- Trailer landing-gear and dolly pads, where the entire trailer weight bears on two small steel plates. Asphalt hates point loads; these spots want reinforced sections or concrete pads.
- Dumpster pads and compactor zones — same point-load problem, plus twice-weekly truck pivots.
- Turning radii and gate entries, where power steering scrubs the surface and every vehicle tracks the same path.
- Anywhere water stands. Drainage isn't a landscaping detail; ponding water softens the base, and a soft base under truck loads fails fast. Grades, inlets, and flow paths belong in the paving plan.
A smart spec doesn't build the whole yard to the worst case — it zones the pavement, putting the money where the trucks go and a standard section where cars park. That's how you get a durable yard without paying for overkill everywhere. This is core new asphalt construction design work, and it's worth doing on paper before mobilization, not improvising in the field.
Rebuilding an existing yard
For an existing facility, the same logic applies in reverse. Rutted or alligatored truck lanes usually mean base failure — those areas need full-depth repair, not another patch. Sections that are worn but structurally sound are candidates for a mill and overlay. Isolated failures get full-depth patching. Phasing keeps the facility operating: docks stay reachable, one zone rebuilds at a time. With the added crew capacity from operating alongside Michael's Asphalt, we can compress that phasing so trucks aren't rerouting for weeks.
Maintenance is cheaper than tonnage
Even a properly built industrial lot needs upkeep: crack sealing before Georgia rain gets into the base, drainage kept clear, and repairs while they're small. An asphalt maintenance program with scheduled inspections costs a fraction of the full-depth repairs it prevents — the ratio isn't close.
