There's no point budgeting to repave your entire asphalt parking lot if only a relatively small area actually needs to be repaved. Ideally you'd like to budget to repave just the area that needs it and then re-allocate the remaining budget to keep the good areas good through pavement maintenance. Typical maintenance tasks include:
- Sealcoating
- Crack-Filling
- Pothole Repair
- Striping & Marking
Forecasting when each task needs to be done is the next step, and this can be difficult on your own. That's where having your parking lot evaluated can help.
Asphalt begins to degrade beginning the day it is laid down. If not properly maintained, your asphalt will likely degrade to the point where your pavement will need serious (costly) work. However, if you catch problems in their early stages, you can take preventative action to avoid future (costly) headaches.
