Common Defects Requiring Asphalt Repair in Washington

Asphalt repair in Washington becomes necessary at some point in wet and dry climates alike. Weather often causes damage, as does human error, which leads to noticeable defects. Here are nine common types of asphalt damage we repair at Jimini Paving:

  • Potholes: These bowl-shaped depressions cause irritation and axle damage throughout the state. Potholes penetrate all through the surface and base layers, which make these extensive repair projects as well as annoyances. They result when you ignore alligator cracking and often arise after winters with heavy rain or snow. You cannot just fill them. Potholes require a full depth replacement patch that starts with asphalt cutting.
  • Alligator cracking: When you see a web of cracks that look like alligator scales, that is a sign of structural failure. Surface weaknesses, base or sub-grade shortcomings and bad drainage lead to alligator cracking. Like potholes, you will often see this arise after an especially rough winter. Since this damage can lead to potholes, contractors must complete a full depth patch and replace the surface.
  • Block cracking: This is like alligator cracking, but with bigger squares. It is not due to use or load, but an ability of the asphalt binder to expand and contract with temperature cycles. Cracks measuring a half inch or less can be sealed. Severe cracks are fixed by moving the cracked pavement layer and replacing the overlay.
  • Linear cracking: These are the cracks that are parallel to the center line. They are often the result of asphalt wearing out or poor joint construction. Like with block cracking, any cracks that are a half inch or smaller in diameter can be filled. Severe cracks require asphalt cutting and a replacement overlay.
  • Transverse cracks: Single cracks perpendicular to the centerline or laydown direction are called transverse cracks. They arise from construction errors and extreme temperature fluctuations. If you catch them early and call us, we can usually fill them, but waiting several months could result in paying for new overlay.
  • Edge cracks: If your drainage is below average or your vegetation grows out into the asphalt, you will likely see edge cracks. They are more likely if there is not enough asphalt support at the edge, which makes water accumulation more damaging. You will need to remove existing vegetation and prepare to have the cracks filled and sealed. If they continue to appear, you likely need to rebuild that section.
  • Slippage cracks: Another result of construction errors, slippage cracks emerge when there is little bonding between layers. Sometimes, less experienced contractors skip a tact coat or fail to clean the surface area before construction. This results in the appearance of stretch marks in the asphalt, and the only effective repair is a partial or full depth patch.
  • Depressions: Also called “bird baths,” depressions are slightly lower elevations in the surface. They will fill with water when it rains and develop into full-blown cracks. Severe depressions require a surface replacement. Less serious ones can be repaired with a thin surface patch.
  • Rutting: Constant vehicle traffic and insufficient asphalt thickness leads to rutting. These larger depressions are shaped like vehicle tires and reveal construction shortcomings. Minor rutting caught early just needs to be filled. Serious rutting needs to be removed and replaced.
