Paving in a Former Coal Town
Asphalt paving in Madrid covers a town with a long history and a newer growth spurt. Madrid was a coal mining community; the Carpenter Coal Company opened a mine between Madrid and Woodward in 1901, and by 1914 the Scandia Coal Company of Madrid produced more than 100,000 tons of coal a year. Today it is known for the High Trestle Trail, and the population has grown from 2,264 in 2000 to 2,543 in 2010 and 2,802 in 2020.
Old and new
Madrid's older homes date from the mining era, with narrow lots and short driveways. Newer homes on the edges of town have wider drives and attached garages. The older driveways usually need replacement or a careful overlay; the newer ones mostly need crack filling and sealing.
Ground conditions
Old mining areas can have uneven fill and settled ground. When a driveway in Madrid sinks in one spot or keeps cracking in the same line, we dig to find out why before we pave over it. Soft or uneven base material is removed and replaced with compacted stone.
Boone County rural drives
Homes outside town on county-maintained roads need a Boone County entrance permit for any new entrance or extension. The permit is free, and Secondary Roads staff evaluate sight distance and drainage on site, including whether a drainage structure is needed. Work in the county right-of-way needs a separate permit with a sketch and an insurance certificate.
Trail-town businesses
The High Trestle Trail brings riders and visitors to Madrid's businesses. Lots near the trail see bikes, cars and pedestrians at the same time. Clear striping, smooth surfaces and good drainage make them safer. We patch, overlay, seal and stripe them in sections so they stay open on busy weekends.
Newer subdivisions
With about 260 more residents in 2020 than in 2010, Madrid has new homes on its edges. Those driveways are best protected early: crack filling before the first winter they show cracks, and a sealcoat every few years after the first season.

Madrid Questions
My driveway keeps sinking in one spot. Why?
Settled fill or soft ground under the base is the usual cause. We dig out the area, find the soft material and replace it with compacted stone before patching.

If it connects to a Boone County road and you are adding or extending the entrance, yes. The permit is free and includes a site visit.
Can you work around trail weekends?
Yes. We phase lot work so businesses near the trail stay open on busy days.
When should I first seal a new driveway?
After it cures for three to six months, usually the season after paving.
