How can I prevent asphalt pavement deterioration and prolong its lifespan?

Regular maintenance is key to preventing asphalt pavement deterioration and extending its lifespan. This includes routine inspections, prompt repair of cracks and potholes, sealcoating every 2-3 years, proper drainage management, and regular sweeping to remove debris and prevent water accumulation, which can weaken the pavement over time. Additionally, avoiding heavy loads and abrasive chemicals can help preserve the integrity of the asphalt surface.

What is the difference between asphalt patching and asphalt repair?

Asphalt patching typically refers to repairing localized areas of damage, such as potholes or surface cracks, by removing the damaged asphalt and replacing it with new asphalt material. Asphalt repair encompasses a broader range of maintenance activities aimed at restoring the overall condition of the pavement, including patching, crack sealing, sealcoating, and resurfacing, depending on the extent of the damage.

Can asphalt overlays be applied to an existing damaged asphalt surface?

Yes, asphalt overlays are a cost-effective solution for rejuvenating worn-out or damaged asphalt surfaces. However, it’s essential to assess the condition of the existing pavement to ensure that it is structurally sound and suitable for overlay application. Any necessary repairs should be addressed before the overlay is installed to ensure optimal results and longevity.

What causes cracks to develop in asphalt pavement, and how can they be repaired?

Cracks in asphalt pavement can result from factors like moisture infiltration, temperature fluctuations, and vehicle traffic. They should be repaired promptly to prevent water damage and further deterioration. Crack repair methods include hot rubberized crack sealing, cold pour crack filling, or infrared asphalt repair, depending on the severity and extent of the cracks.
