Asphalt Sealcoating in St. Joseph, IL
St. Joseph is a Champaign County village in St. Joseph Township, founded in 1881, with Interstate 74 along its north edge and its own exit at 192. U.S. Route 150 and the Kickapoo Rail Trail, which follows the old Big Four railroad right-of-way, run between the village and Urbana. The population history explains a lot about the pavement here: 2,912 residents in 2000, 3,967 in 2010, a jump of more than a third in one decade, then 3,810 at the 2020 Census.
Census estimates put the median St. Joseph home at 1996, and about two in five homes were built between 2000 and 2009. More than four in five are owner-occupied. That leaves a large group of driveways of about the same age, most now more than fifteen years old. Whether they were sealed on schedule or never sealed at all, they have reached the stage where oxidized binder and hairline cracks decide how the next ten years go, and crack filling ahead of the next coat is the inexpensive part of that decision.
A decade of driveways, all coming due together
The Salt Fork, one of the six major watersheds the USDA soil survey lists for Champaign County, is crossed by the Kickapoo Rail Trail near the village. The soil matters as much as the river. Flanagan, a prairie soil the USDA described from the University of Illinois south farm near Champaign, is somewhat poorly drained and 35 to 42 percent clay, with a perched water table one to two feet down at some point between January and May in most years. Where a St. Joseph lot sits on ground like that, its driveway base stays wet through the months when prairie clay and freeze-thaw do their work.
For St. Joseph's 2000s driveways, that makes timing matter. Cracks that open over summer let water into the base just ahead of the soil's wettest months, so the useful sequence is to walk the drive in late summer, fill the open cracks, and seal during a dry, warm stretch. A subdivision drive that has never been sealed is still worth starting on while the surface is intact. Once cracks have joined into blocks or the edges have started to break away, patching comes first and sealer after, because a coating cannot hold together pavement that has already come apart.

St. Joseph FAQs
A St. Joseph driveway from the 2000s has never been sealed. Is it too late to start?
Usually not, if the base is sound. Asphalt starts oxidizing as soon as it goes down, so a drive from the building boom will be grayer and more porous than it was, but a sealcoat still slows further drying and keeps water on top of the surface instead of in it. The cracks need filling and any broken edges need patching first, because sealer is a thin film that cannot bridge them. If most of the surface has turned into connected blocks, the money is better spent on repair.
Can coal-tar sealer be used on a St. Joseph driveway?
Illinois has no statewide ban. The Illinois Department of Public Health counts at least 16 municipalities in the state that have banned coal-tar sealants, including Evanston, South Barrington, Riverwoods and Winnetka, and the state's disclosure law, Public Act 102-242, applies to public schools, school districts, day care centers and state agencies rather than homeowners. Village rules can go further than state law, so a call to the village office before the job is sensible, and so is asking the contractor to name the product on the quote.
Why do St. Joseph driveways of the same age look so different?
Because age is only one input. Two drives paved the same summer can differ in sun exposure, in how water leaves the lot, in how heavy the vehicles on them are, and above all in whether anyone sealed them. A drive in full sun oxidizes faster than a shaded one, and a drive that holds a puddle by the garage takes on water every time it rains. Comparing a neighbor's drive is useful, but the assessment has to be of the drive itself, cracks, edges and low spots included.
