How Much Cheaper Is Asphalt Than Concrete?

Posted on: July 23, 2022

Asphalt is significantly cheaper than concrete. It expands and contracts with changes in temperature, unlike concrete. Furthermore, asphalt is far less likely to stain, which makes it ideal for patios and walkways. Asphalt can also be repaired or re-layered, whereas concrete needs to be completely replaced if it is damaged. So, which is better? Read on to discover the benefits of asphalt over concrete and decide for yourself.

Cost comparison

When comparing the cost of paving a driveway, you’ll find that concrete costs an average of $6 per square foot, while asphalt is a bit cheaper, ranging from $3 to $4 per square foot. Asphalt can be aesthetically pleasing as well, with the ability to be stained, tinted, texturized, and stamped. Both materials need sealing every three to four years, though concrete may require more maintenance.

Decorative concrete finishes also benefit from sealers. They help minimize surface abrasion, making it easier to clean and prevent stains and oils from penetrating the material. Another benefit of precast concrete paver driveways is the ability to easily replace individual pavers if one or more are damaged. For instance, if a paver cracks or sunken, it can simply be replaced without damaging the rest of the driveway.

Durability

There are several factors that affect the long-term durability of asphalt, including the gradation of the aggregate, the composition of the binder, and the freezing-thawing cycles. The most important factor affecting frost resistance is aggregate gradation, which plays a crucial role in ensuring a dense filling. As the void water expands during freezing, it erodes the interior of the mixture, reducing its overall durability.

It is necessary to consider the climatic conditions in different parts of the world when predicting the durability of asphalt. The southern U.S. and Australia may require highly durable asphalts for the long-term surfacing, while moderately durable asphalts will suffice for temperate climate regions. However, the climatic conditions in northern Canada and the U.S. are outside of the range of the model, and binder hardening does not occur at the same rate in the northern regions. Therefore, the level of durability may be irrelevant for predicting the life of asphalt pavements in these regions.

Maintenance

The cost of asphalt maintenance varies between a homeowner and a professional contractor. Asphalt is relatively cheap and can last for more than 20 years if properly maintained. Compared to concrete, asphalt replacement is often only necessary to replace the top layer. This means that you can save thousands of dollars over the life of your pavement. Even if it is not the most attractive surface, proper maintenance can save you from costly repairs. Here are some benefits of asphalt maintenance.

Potholes, cracks, and repairs require intensive measures to fix. Potholes and cracks often signify a larger problem. In some cases, they may indicate a weakened sub-base. Poor construction, water infiltration, and heavy vehicles can all cause a sub-base to fail. Pothole repair costs are generally determined by the size of the pothole or crack. The size of the damaged area will also determine the cost.

Life span

The life span of an asphalt pavement depends on a number of factors, including quality of construction, weather, and traffic. For example, an asphalt road built for 100,000 ESALS may only last 15 years or less. After that, major repairs may be necessary. Fortunately, there are ways to extend the life of asphalt. These methods include asphalt overlays and resurfacing. If you want to preserve the life of your asphalt road, follow these tips.

Regular maintenance is also important. A high-quality asphalt surface can last for up to 20 years with proper care. Overlays, on the other hand, are more prone to deterioration and may last only ten or fifteen years. In addition, the type of traffic on the asphalt surface can affect the lifespan. For example, a parking lot with light traffic may last only five years, while a roadway with heavy traffic can last for twenty to thirty years.
