Ruts in an Asphalt Driveway: How to Fix Them

Ruts are long depressions that follow the wheel paths. They form when the asphalt, the base under it, or the soil below gets pushed down and sideways by repeated loads. The fix depends on which layer moved. Shallow ruts in a firm driveway can often be filled with hot mix, reworked with infrared repair, or covered with an overlay. Deep ruts with cracking, soft spots, or water problems usually mean the base or subgrade gave way, and the lasting fix is to cut out the area, rebuild and compact the base, and repave. Cold patch can smooth shallow ruts for a while but tends to shove back out under tires.

What Causes Ruts in Asphalt?

• Weak or thin base. A common cause on driveways. Not enough compacted stone to spread the load.
• Soft subgrade. Clay or wet soil under the base that deforms under weight.
• Water. Poor drainage softens the base and soil, especially in spring thaw.
• Heavy vehicles. Delivery trucks, RVs, dumpsters, or equipment that exceed what the driveway was built for.
• Hot weather. Asphalt softens in heat. A mix with too much binder can deform under traffic on hot days.
• Same-spot parking and turning. Parking in the same place and turning wheels while stopped concentrates stress.

Road agencies such as the Washington State DOT describe rutting as permanent deformation in the wheel path, often from heavy loads on pavement without enough structural strength, and note that ruts can trap water.

Surface Ruts vs Base Ruts

Surface (mix) ruts:

• Usually shallow
• Often show up in hot weather or where vehicles park or turn
• Surface may have small ridges pushed up beside the rut
• No cracking or soft feel

Base or subgrade ruts:

• Deeper and wider
• Cracks along or inside the rut, sometimes alligator cracking
• Soft or spongy when you walk or drive on it
• Water pools in the rut after rain

Our guide on asphalt driveway soft spots explains how to tell if the base is failing.

Options for Fixing Ruts in Asphalt Driveway Surfaces

1. Rut Filling With Hot Mix

For firm driveways with shallow ruts, a contractor can clean the rut, apply tack coat, and fill it with hot mix, compacting it well. On highways, crews place rut fill in layers and use rubber-tired rollers because steel drums can bridge over the dip. On a driveway, a plate compactor or small roller is common.

2. Infrared Repair

Infrared heating softens the existing asphalt so it can be raked, topped with new mix, and compacted without saw-cut joints. Our infrared asphalt repair guide explains when it fits. It suits localized surface ruts on a stable base.

3. Mill and Fill or Overlay

When ruts and wear are widespread but the base is firm, milling the surface and paving a new layer, or overlaying the whole driveway, restores a smooth surface.

4. Remove and Rebuild

For base failure:

1. Saw-cut around the damaged area
2. Remove the asphalt and soft base
3. Fix drainage or soft soil
4. Add and compact new crushed stone base in lifts
5. Pave with hot mix and compact

This is the only lasting fix when the base has failed. It costs more up front, but it stops the cycle of patching the same ruts every spring.

5. Cold Patch (Temporary)

Cold patch can fill shallow ruts short term, but it stays softer than hot mix and often gets pushed out under wheel loads. It's best as a stopgap until a proper repair.

Estimating Material

Hot mix example: A rut area 20 ft long, 2 ft wide, averaging 1.5 inches deep.

• Volume: 20 × 2 × (1.5 ÷ 12) = 5 cubic feet
• Weight at about 145 lb per cubic foot: 725 lb, about 0.36 tons

Small amounts like this are usually handled by a contractor's crew rather than bought by the ton. Hot mix commonly costs $90 to $130 a ton at the plant (region and season move it, and trucking is extra), and many plants set minimum orders.

Cold patch example (temporary): The same 5 cubic feet can be counted two ways:

• By listed yield: at a common yield of about 0.5 cubic feet per 50-lb bag, 5 ÷ 0.5 = about 10 bags
• By weight: at about 145 lb per cubic foot once compacted, 725 lb ÷ 50 = about 15 bags

Plan on roughly 10 to 15 bags, and check the yield printed on your bag, since products vary. Our guide on how many bags of cold patch has the formula.

How to Prevent Ruts

• Keep heavy vehicles off or build a thicker base where they'll drive. This guide to driveway load limits explains what to watch for.
• Fix drainage so water doesn't soak the base.
• Vary parking spots and avoid turning wheels while stopped, especially on hot days.
• Use plywood or mats under trailer jacks, dumpster rails, and equipment.
• Seal cracks to keep water out of the base.
• Build it right. New driveways need an adequate, well-compacted base for the traffic they'll carry.

Bottom Line on Fixing Ruts in an Asphalt Driveway

Fixing ruts in asphalt driveway surfaces starts with finding which layer moved. Shallow surface ruts on a firm base can be filled, reheated with infrared, or overlaid. Deep ruts with cracks and soft spots need the base rebuilt. Fix drainage, manage heavy loads, and use cold patch only as a stopgap.
