Asphalt maintenance goes beyond just sealcoating. A lot of damage to asphalt can occur with water intrusion through cracks in the asphalt. Crack filling is an essential application in addition to sealcoating for long term pavement protection.
Controlling vehicle speed with speed humps or speed bumps is the most effective method to improve the safery of a parking lot, driveway or private lane. Highly-visible speed bumps/humps and signage are the best ways to communicate to drivers to keep their speed to a minimum.
