Identifying And Repairing Asphalt: Types Of Pavement Damage

​Maintaining the integrity of asphalt pavement is crucial for property owners in Myrtle Beach, SC, where the coastal climate can accelerate wear and tear. Understanding the various types of asphalt damage and their appropriate repair methods can significantly extend the lifespan of your pavement, ensuring safety and enhancing curb appeal.​

Identifying And Repairing Asphalt: Types Of Pavement Damage

Common Types of Asphalt Pavement Damage

• Block Cracking: Characterized by interconnected cracks forming rectangular patterns, block cracking often results from asphalt binder aging or poor installation techniques. In Myrtle Beach’s warm climate, thermal expansion and contraction can exacerbate this issue. Timely sealcoating can prevent moisture infiltration and delay further deterioration.​

• Edge Cracking: These cracks develop along the outer edges of the pavement and are typically caused by inadequate support at the pavement’s edge, poor drainage, or heavy vegetation growth. Removing encroaching vegetation and improving drainage can mitigate this problem. Filling the cracks with asphalt emulsion restores the pavement’s integrity.​

• Fatigue Cracking (Alligator Cracking): Resembling alligator skin, fatigue cracking indicates structural failure due to repetitive traffic loading or an insufficient subbase. In areas with high traffic, such as commercial properties in Myrtle Beach, addressing this issue promptly is essential. Full-depth patching is often required to restore structural integrity.

• Linear and Transverse Cracking: Linear cracks run parallel to the pavement’s centerline, while transverse cracks are perpendicular. These cracks can result from temperature fluctuations, asphalt shrinkage, or reflective cracking from underlying layers. Sealing these cracks prevents water intrusion and further damage.​

• Rutting: Depressions or grooves in wheel paths, known as rutting, occur due to inadequate pavement thickness or weak asphalt mixes unable to support traffic loads. In Myrtle Beach, where tourism increases vehicular traffic, addressing rutting is vital. Milling and overlaying the affected area can rectify this issue.​

• Potholes: Potholes are bowl-shaped depressions caused by moisture infiltration and subsequent weakening of the pavement structure. They pose hazards to vehicles and pedestrians alike. Prompt pothole repair using appropriate patching techniques is essential to maintain safety and prevent further deterioration.​

• Raveling: This occurs when the asphalt surface disintegrates, leading to loose aggregate and a rough texture. Raveling can result from poor compaction during installation or the use of inferior materials. Surface treatments or overlays can address this issue effectively.​

• Bleeding: Bleeding is the exudation of asphalt binder onto the pavement surface, creating a shiny, sticky appearance. It often results from excessive asphalt content or hot temperatures causing the binder to soften. Applying sand to blot the excess binder or milling the surface can remedy bleeding.​
  

Repair Techniques for Asphalt Damage

• Crack Sealing: This preventive measure involves filling cracks with sealant to prevent water infiltration, which can cause further damage. Regular crack sealing is crucial in Myrtle Beach’s humid climate to maintain pavement longevity.​

• Pothole Patching: Depending on the severity, potholes can be repaired using cold mix or hot mix asphalt. Proper cleaning and preparation of the pothole are essential for a durable repair.​

• Overlaying: Applying a new layer of asphalt over the existing pavement can address surface distresses and improve ride quality. This method is cost-effective for pavements with moderate damage.​

• Full-Depth Reclamation: For pavements with extensive structural damage, reconstructing the pavement by recycling the existing materials can provide a stable base for new asphalt.​
  

Preventive Maintenance Strategies

• Sealcoating: Applying a protective sealant every few years shields the asphalt from UV rays, water, and chemicals, extending its lifespan.​

• Regular Inspections: Scheduled assessments help identify early signs of damage, allowing for timely interventions before issues escalate.​

• Proper Drainage: Ensuring adequate drainage prevents water accumulation, which can weaken the pavement structure.​
