Common Asphalt Problems
There are many common asphalt paving scam and issues to watch out for. Each has clues that indicate what is needing repair. These are the most common to watch for:
- Oxidation and Graying
- Linear Cracks
- Alligatoring, Check Cracking, Spider Web Cracking
- Weeds, Grass And Vegetation
Recognizing the Issues
Oxidation and graying is easily recognized. The pavement will have lost its original deep black color and will begin to look gray. Over time rain or other water, petroleum products, UV rays from the sun, and traffic will cause the asphalt binder to dry out causing the color of the asphalt to fade to gray. It is important to add a sealer at this stage so that that pavement doesn’t begin to show further issues.
Raveling happens as the pavement ages and the asphalt binder which holds the aggregate together begins to deteriorate and can no longer hold the sand and stone particles together properly. You’ll recognize raveling because the pavement will look very rough and the individual stones can be seen. Adding a sealcoat immediately will help to prevent further deterioration.read more information on Improving the Durability of Open-Graded Asphalt Mixtures by clicking here
Linear cracks will start out small but will expand as the pavement wears. Water, as well are other debris, is able to penetrate the asphalt through the crack causing further damage and problems in the asphalt. These cracks can be recognized as a small thin hairline crack. If left unrepaired, over time the crack will widen and the asphalt at the edges will begin to crumble. A crack sealant will prevent further cracking.
Alligatoring, check cracking, and spider web cracking are different from linear cracks. These cracks will spread out, appearing much like a spider’s web, and will cover larger areas of the pavement. Alligatoring in particular will have the look of that of the skin of an alligator. Like linear cracks it is necessary to repair these as quickly as possible with a crack sealer.
Weeds, grass, and Vegetation are problematic when they begin to grow through unsealed cracks in the asphalt. The vegetation will root into the pavement and as it grows it will cause the crack to further expand allowing for further deterioration. The solution is to remove the weeds and grass, clean the crevices in the asphalt and then use a sealer.
Remembering to sealcoat asphalt paving every 2 to 4 years will help to lessen or prevent these and other problems all together. When asphalt problems and issues are caught early they can be repaired quickly and inexpensively and will help keep the pavement in top condition.
