The Champaign Asphalt Blog
Champaign pavement lives between two forces: a shrink-swell prairie clay underneath and a winter of many shallow freezes on top. Willard Airport averages about 123.5 days a year at or below 32 degrees F, the ground under most of the city carries a seasonal water table from January into May, and the city's plow trucks spread rock salt and calcium chloride that ends up on every driveway apron. This blog explains what that does to asphalt and what to do about it.
Each post is written for a Champaign, Urbana, Savoy, Mahomet or Rantoul homeowner or property manager with a specific question: when the sealcoating season opens and closes, why cracks come back in the same place, which sealer chemistry Illinois rules allow, and how to phase and stripe a parking lot. Figures come from NOAA normals, the City of Champaign, USDA soil descriptions and state guidance, and every post links to the service page that fits the job.

Parking Lot Sealcoating for Champaign Property Managers: Phasing, Striping and the ADA
A lot on Champaign clay needs a plan, not a one-time coat: sections that keep the doors open, stripes that meet the 2010 ADA Standards, and a calendar that beats both the frost and the move-in trucks.
