Pothole Repair in Anderson: Throw-and-Go Cold Patch vs Cut-and-Fill Hot Mix

October 1, 2026

Two repairs, two different jobs. One buys you a season. The other is meant to still be there in three years.

A pothole is a failure in the base, not just a hole in the surface

A pothole does not start at the top. Water finds a crack or a porous spot, works down to the stone and soil carrying the asphalt, and freezes. Water expands roughly nine percent when it freezes, so every cycle lifts the slab and churns the material underneath into something looser and wetter. Come the thaw, the support is gone, and a few hundred passes of traffic caves the surface in.

Anderson supplies the weather. The Indianapolis station records 98.6 days a year at or below 32 degrees F, and the Great Lakes regional average runs about 42 freeze-thaw cycles a year. Under a typical driveway of four inches of asphalt over six inches of stone sits Crosby soil: somewhat poorly drained, 35 to 45 percent clay below, with a perched water table 0.5 to 2.0 feet down through winter and spring. Water that gets in has nowhere to go, which is the whole story in the guide on why Anderson driveways fail from the bottom up. Replace only the missing surface and the new material sits on the same ruined base.

Throw-and-go cold patch: fast, temporary, and sometimes the right answer

Cold patch is pre-mixed asphalt that stays workable at ambient temperature. It goes into a cleaned-out hole, gets tamped, and takes traffic right away. No plant, no cure window, no waiting on a 50 degree day.

What it does not do is bond to the surrounding pavement or restore structure. It is a plug held in place by compaction and the shape of the hole. On a shallow or tapered hole it works loose. Under a plow blade it gets caught and dragged out. After a wet winter on clay it often pumps out, leaving the hole wider than it started.

None of that makes it wrong. Cold patch is right when the job is getting safely through a season: a hole that opens in January, a trip hazard beside a walkway, a lot that cannot close until spring.

Cut-and-fill hot mix: the repair built to outlast a winter

A cut-and-fill repair squares the failure off, cutting straight edges back into sound asphalt, then removes the broken material and deals with what is under it. Where the stone has gone wet and contaminated, it comes out too and gets replaced and compacted. Hot mix goes back in lifts, each one compacted, and the perimeter joint gets sealed so water cannot return at the seam.

The trade is scheduling. Hot mix has to go down while it is still hot, so the work depends on plant availability and weather, and the area stays closed for a few hours. In exchange the patch behaves like pavement rather than filler, and the edges do not unravel the first time a blade catches them.

Reading your own hole before anyone quotes it

Two minutes over the hole tells you most of what you need.

• Depth. If the hole bottoms out in stone or soil rather than asphalt, the base is involved and a surface plug will not hold.
• Edges. Vertical, sound edges take hot mix cleanly. Crumbling, alligatored edges mean the failure is wider than the hole looks and the cut has to go further.
• Water. Standing water a day after rain, or a dark halo around the hole, points at drainage rather than the pavement itself.
• Company. One isolated hole in tight asphalt is a patch. A line of holes along the same path is usually a saturated strip wanting one larger cut, not four small ones.
• Traffic. Where cars turn, brake, or park in the same spot daily, a bonded hot mix patch pays off sooner.

Early October is a patching month, not a sealing month

By late September the sealing season in Anderson has effectively closed. Sealer needs pavement at roughly 50 degrees F and rising plus about 24 dry hours, and it is only a surface film about as thick as a business card. It was never going to fill a hole, and in October it will not cure.

Patching and crack filling are a different category of work. Both tolerate cooler pavement than sealer does, and both are worth the most now, before INDOT brine and driveway deicers arrive in mid-November. A hole left open through winter takes on water at every thaw and gets bigger. Asphalt patching scheduled in October works with the calendar rather than against it.

Where patching sits in the order of operations

The sequence does not change with the season: fix drainage first, fill cracks annually, patch before winter, seal every two to three years, stripe last. Patching sits third for a reason. Draining the water that caused the hole comes before replacing what the water destroyed, and sealing around an open hole spends money on the wrong layer.

Anderson's housing stock keeps this conversation busy. The median construction year is 1961 and 63.3 percent of homes here predate 1970, so many driveways have absorbed decades of the cycle counts on the Anderson pavement data page. On pavement that old, the question is usually not whether to patch but how far back to cut.

If a quote needs sorting out, the things that move the number are on the cost page, and recurring patch-and-fill work folds into asphalt maintenance plans so holes get caught in October, not March.
