Why Asphalt Driveways Crack and How to Prevent It

October 24, 2024

Save Your Driveway, Keep Your Peace of Mind

Asphalt driveways are a popular choice for many homeowners due to their durability and sleek appearance. However, over time, asphalt can start to show signs of wear and tear, with cracks being one of the most common issues. Cracked asphalt not only affects the aesthetics of your driveway but can also lead to more significant damage if left untreated. Understanding why asphalt driveways crack and how to prevent this from happening can save you time, money, and frustration in the long run.

Common Causes of Asphalt Driveway Cracking

1. Moisture Infiltration

Water is one of the most significant culprits behind asphalt cracking. When moisture seeps into the tiny pores of your driveway, it can weaken the structure of the asphalt. During cold weather, the water freezes and expands, causing the asphalt to crack. As temperatures rise, the ice melts, creating gaps in the pavement that lead to even more significant cracks over time.


2. Freeze-Thaw Cycles

The freeze-thaw cycle is especially problematic in regions with fluctuating temperatures. When the water trapped inside the asphalt freezes, it causes the material to expand. As the ice melts, the asphalt contracts. Repeated cycles of freezing and thawing lead to stress fractures in the pavement, which worsen over time.

3. Heavy Traffic

Driveways are meant to handle the weight of vehicles, but constant heavy traffic can cause damage, especially if the asphalt is older or hasn’t been maintained properly. Over time, the constant pressure can lead to surface cracks, which, if left untreated, will expand and deepen.


4. Sun Exposure

UV rays from the sun can cause asphalt to dry out and become brittle. This can lead to cracking, especially if the driveway hasn’t been sealed regularly. As the material weakens, small cracks can form, which will grow larger without proper care.


5. Poor Installation

Sometimes, cracks appear simply because the driveway wasn’t installed correctly. If the base layer beneath the asphalt isn’t properly prepared, it can cause uneven settling, leading to cracks and potholes in the asphalt surface. Choosing a reputable contractor to install your driveway is key to ensuring it lasts for many years.

How to Prevent Cracks in Asphalt Driveways

1. Regular Sealing

One of the most effective ways to prevent asphalt cracking is to have your driveway sealed regularly. Sealing creates a protective layer on the surface that shields it from water, sun, and other environmental factors. Salisbury Pro Sealers recommends sealing your driveway every two to three years, depending on its condition and the climate in your area.



2. Proper Drainage

Ensure your driveway has adequate drainage to prevent water from pooling on the surface. Water that remains on your driveway after a rainstorm can seep into the asphalt and cause damage. Installing a drainage system or sloping the driveway to allow water to run off can significantly reduce the chances of cracking.

3. Fill Cracks Early

Even with proper maintenance, small cracks can still appear over time. Addressing these cracks as soon as they appear can prevent them from growing into larger problems. Salisbury Pro Sealers offers professional crack filling services to ensure your driveway remains in top condition.


4. Avoid Heavy Loads

If possible, try to avoid parking heavy vehicles, such as large trucks or trailers, on your driveway for extended periods. The constant weight can stress the asphalt and lead to cracks. If you need to park heavy equipment on your driveway, consider using a protective surface to distribute the weight evenly.


5. Protect Against UV Damage

While you can’t avoid sunlight, you can protect your driveway from UV damage by applying a UV-resistant sealant. This will help keep the asphalt from drying out and becoming brittle. Regular sealing, combined with UV protection, will prolong the life of your driveway and keep it looking fresh for years to come.

Make an Informed Decision Concrete is one of the most durable and versatile materials used in driveways, patios, walkways, and commercial surfaces. However, over time, exposure to weather, heavy traffic, and natural wear and tear can cause concrete to crack, chip, or discolor. When these issues arise, property owners face an important decision: Should they resurface the concrete or replace it entirely? At Salisbury Pro Sealers, we help customers determine the best approach based on their budget, needs, and the current condition of their concrete surfaces. In this article, we will break down the differences between resurfacing and replacement, their benefits, and how to decide which is the right solution for your property. What is Concrete Resurfacing? Concrete resurfacing is a cost-effective method for repairing and refreshing existing concrete without having to remove and replace the entire surface. The process involves cleaning and prepping the concrete, filling in cracks and minor imperfections, and then applying a thin overlay of specialized concrete coating. This coating bonds to the original slab and creates a smooth, renewed, and durable surface.
