The time line below explains progressive deterioration of the typical asphalt parking lot that goes unprotected. Please keep in mind that certain flaws will vary from lot to lot based on original asphalt mix and compaction, weather, water drainage, traffic etc. It is recommended that asphalt be properly maintained in order to extend the life of the parking lot and before basic repairs become a huge expense.
| New asphalt is set in place with the appropriate base course (crushed rock), grade and compaction. Looks Great!! | ||
| It starts to show signs of oxidation due to the weather and looks faded and gray. | ||
| Oxidation continues, asphalt may start breaking up on top surface(raveling). The asphalt starts to lose the properties that help it deter water. | ||
| Oxidation and Raveling continue and become much more visible. Surface cracks may begin to develop. | ||
| Surface cracks get worse and deeper, allowing water to enter. | ||
| Water that has been seeping in will freeze, expand and contract. This will cause movement of asphalt in areas (upheaval) and sink holes. | ||
| Larger cracks and holes develop where asphalt has been shifting. Large amounts of water are now entering the substrate. | ||
| The deterioration is so severe now that sections of the asphalt are lose and easily displaced by car traffic, foot traffic and running water. | ||
| Asphalt pavement is no longer functional and it looks awful. At this point it is beyond repair and must be replaced. |
The ideal time to start preventive maintenance would be around year 2. Cleaning and Sealing your asphalt will help extend the life. Cleaning and Sealing your asphalt should be a regular part of your maintenance routine. Any visible cracks should be addresses as soon as possible.
