Asphalt is a popular choice for driveways, parking lots, and roads for good reason. It’s durable, cost-effective, and relatively easy to maintain. If you’re planning a new asphalt installation or considering when to replace your existing asphalt pavement, you’re probably asking: how many years does asphalt last?
The truth is one doesn’t fit all. The lifespan of asphalt is variable based on traffic levels, weather conditions, material quality and level of maintenance. Let’s dive in!
Discussing the Lifespan of Asphalt
How long does asphalt last? It depends on where it’s used and the quality of the installation. Residential driveways typically last 15–20 years, while commercial parking lots asphalt average 12–15 years. Roads and highways are built with heavier traffic and thicker pavement layers in mind, allowing them to last 20–25 years or more when properly maintained.
While these are the averages, even the best asphalt won’t last without proper installation and regular maintenance. The foundation, compaction, and mix type all determine how long your asphalt lasts.
Factors That Affect Asphalt Longevity
Asphalt has a variable lifespan. Some factors you can control, while others you cannot. Here’s what makes a difference:
Traffic & Load
Traffic affects asphalt the most. For example, residential driveways only see light car use, so the surface experiences less stress. Meanwhile, commercial areas or industrial zones that deal with heavy trucks, frequent deliveries, and higher vehicle turnover are areas where asphalt won’t last as long. Even small cracks or potholes can form sooner if the asphalt isn’t designed to handle the load.
Climate & Weather Conditions
The weather makes a big difference. Hot summers can soften asphalt, leading to indentations from heavy vehicles. Meanwhile, Winnipeg’s bitter cold winter can cause cracking as a result of freeze-thaw cycles. If the surface isn’t sealed properly, moisture from rain or snow can cause the surface to deteriorate faster.
Quality of Materials & Installation
Asphalt has variable quality. Hot mix asphalt is professionally laid and compacted, providing a long-lasting surface. Cold patch asphalt works better for small repairs, but doesn’t last as long. Proper installation by a professional property maintenance service provider in Winnipeg is essential. However, a poorly prepared base, improper compaction, or uneven thickness can reduce the lifespan of asphalt, no matter the material.
Maintenance & Upkeep
Taking care of your asphalt is the best way to make it last longer. Sealcoating is an effective way to protect against water and UV damage, while patching cracks and potholes sooner rather than later prevents them from spreading. Cleaning debris and snow from the surface also reduces wear and tear. Ignoring repairable issues can lead to a full replacement down the line.
Signs Your Asphalt Needs Replacement or Repair
Knowing when to repair or replace your asphalt can save time and money down the line. Common signs include:
- Cracking, potholes, or depressions
- Surface raveling or loose aggregate
- Fading colour or loss of binder
- Pooling water due to drainage issues
It’s better to address these problems early. It can prevent major damage and help your asphalt last longer.
Ways to Make Your Asphalt Last Longer
Even the best asphalt won’t last long if you don’t take care of it. Here are some ways to maximize longevity:
- Sealcoat every 2-3 years to protect against water and UV rays
- Inspect the surface regularly and repair cracks or potholes quickly
- Avoid heavy vehicles or standing water on new asphalt
- Invest in professional installation or resurfacing when needed
