An overlay is generally 2 inches of new asphalt paved over the existing asphalt. Typically, a ½ inch scratch leveling course is paved, as necessary, to level out the parking lot and then a 1 ½ inch surface course is paved over the scratch leveling course.
When deciding to overlay in lieu of grinding the parking lot, Surface Engineering will consider the following:
Grinding or Milling Existing pavement down, generally 2-4 inches, is an another resurfacing option. Grinding a parking lot before paving new asphalt eliminates reflective cracking and allows for the entire parking lot to be leveled before the surface course of asphalt is paved.
Grinding a parking lot offers an opportunity to inspect the aggregate base and re-grade if necessary. When grinding, it’s important to analyze existing drainage and install new drainage where necessary.
When deciding to grind in lieu of overlaying a parking lot, Surface Engineering will consider the following:
You should expect a Northeast Ohio parking lot to last approximately 15 years with proper maintenance.
You should sealcoat your parking lot every 2 to 3 years based on traffic patterns.
We recommend that you sealcoat your lot the first year after installation. Regular maintenance such as crack sealing and line striping should be performed every 2-3 years. Also temps need to be at 50 degrees and rising. May through October.
Crack sealing should be performed as part of your regular asphalt maintenance program, every 2-3 years in Northeast, Ohio.
Yellow is the best choice for line striping in northeast Ohio due to its weather patterns.
With over 50 Years of asphalt sealcoating and paving experience, trust your parking lot to the pros.
