Asphalt Maintenance Plans in Sioux Falls, SD

An asphalt maintenance plan is a written schedule of inspections and small treatments that keeps a lot or long driveway from reaching the point of major repair, and in Sioux Falls it follows the same reasoning the city applies to its own streets. Public Works puts a half-inch slurry seal on streets that are still in good condition to extend the time before major rehabilitation, and mills and overlays the ones that have worn out. A private plan does the same on a smaller scale: find cracks and weak spots early, fill and patch them in the right weather, and seal before the surface loses its binder. The value is in the timing, because the local season for each task is short.

The local calendar sets the plan. March brings the most freeze-thaw crossings, close to 20 at Foss Field, and South Dakota allows spring load limits on roads from February 15 to April 30 while the ground thaws. An inspection belongs right after that, in late April or May, to map new cracks, heaves and potholes. Crack sealing fits May and late September into October, when the air sits in SealMaster's 45 to 65 degree range. Sealcoat and striping fit June through August, the only months when the normal overnight low stays above 50 degrees.

A three-year cycle is typical. SealMaster's usual resealing interval is about three years, with a third coat on drive lanes and entrances, and HomeGuide's estimate for striping life is 2 to 5 years. A plan for a mid-size lot might run like this: inspection and crack sealing every year, patching as needed, sealcoat and a full restripe in year one, and a refresh of the most-worn markings in the years between. SealMaster puts the case for the approach plainly, estimating that a program of crack filling and sealcoating can more than double pavement life.

Winter preparation belongs in a Sioux Falls plan. Marking curbs, islands and lot edges before the first snow gives plow operators something to steer by, and crack filler finished in a thin band is less likely to be torn out by a blade, a risk SealMaster flags. Deciding in advance where snow will be piled keeps it off drains and away from low spots, since those piles melt and refreeze into March. The state highway department notes that salt works only down to about 15 degrees, and Foss Field averages about 92 nights a year at or below 20, so a lot also needs a plan for sand and for sweeping it up in spring.

Records make a plan useful. The city's Engineering division publishes a pavement condition map for public streets; a private owner can keep a simple equivalent with photos and a marked-up site plan each spring, noting crack footage, patched areas and the date of each seal. With those numbers a contractor can price each task by the unit, and SealMaster's contractor rates run 10 to 30 cents per square foot for sealcoat and 35 cents to $1 per linear foot for crack sealing. The cost page lists the other ranges, and crack filling explains the yearly step.
