Climate Impacts on Asphalt: A Central California Coast Ground Paving Expert's Guide

Climate plays a significant role in the performance and longevity of asphalt paving. As ground paving experts serving the Central California Coast, we’ve observed how our unique climate—characterized by mild temperatures, occasional rainfall, and significant sun exposure—affects the quality and durability of asphalt surfaces. In this post, we'll explore how factors like temperature fluctuations, moisture, and sun exposure impact asphalt and what can be done to mitigate these effects.

Temperature Fluctuations

Asphalt is a temperature-sensitive material that expands in heat and contracts in cold. These expansions and contractions can lead to the formation of cracks, particularly if the fluctuations are sudden or extreme. While Central California is known for its moderate temperatures, even minor temperature swings can still have an effect. In such cases, a professional sealcoat application can provide an extra layer of protection, preventing water from seeping into these tiny cracks and exacerbating the damage.


Although our region is relatively dry, we still experience periods of rainfall, particularly in the winter months. Moisture is a significant factor in asphalt deterioration. When water seeps into cracks in the asphalt, it can erode the underlying layers, leading to potholes or extensive damage. It’s crucial to maintain good drainage around the pavement to prevent water accumulation and to repair any cracks promptly to prevent water ingress.

Sun Exposure

Sun exposure is a major concern in our sunny region. Prolonged exposure to UV rays can oxidize the asphalt binder, causing the pavement to become brittle and more prone to cracking or chipping. A high-quality sealcoat not only shields the asphalt from harmful UV rays but also restores its dark, attractive finish.

The key to prolonging the life of your asphalt pavement in our climate lies in regular maintenance:

1. Sealcoating: Regular sealcoating every 2-3 years can protect your asphalt from the effects of temperature fluctuations, moisture, and UV rays.

2. Crack Sealing: Prompt repair of cracks can prevent water from infiltrating the pavement, protecting it against potential moisture damage.

3. Proper Drainage: Ensuring that your pavement has adequate drainage can prevent water accumulation and reduce the potential for moisture-induced damage.

In conclusion, while our Central California Coast climate does pose some challenges to asphalt longevity, these can be effectively managed with appropriate care and maintenance.
