You’ve got two main choices when it comes to choosing the correct materials for your parking lot paving, sidewalk paving, or driveway paving. These choices are asphalt and concrete. So, how can you choose the right one for you? Is asphalt better than concrete? Does concrete last longer compared to asphalt? What about load distribution and durability?
Today, we’re going to share with you the main differences between the two materials for your paving. We’re also going to explain why concrete is better. So, before you hire a concrete contractor, here are several things you should know:
Both concrete and asphalt paving incorporates a base made from a mixture of aggregates. Usually, they include some sort of gravel, sand, and stone. Aside from the similarities in the composition of its base, these two materials are pretty unalike when it comes to properties.
- Concrete Paving
This is also known as rigid pavement. It includes a mixture of cement adhesive and durable aggregates. Since it’s a rigid pavement, concrete boasts excellent durability. It enables it to widely distribute the load evenly throughout the subgrade under the surface.
- Asphalt Paving
This is also called the flexible pavement. It includes an adhesive that is oil-based. This will hold together the different aggregates. It is also weaker since asphalt is more flexible compared to concrete. Because of this, it does not widely or evenly distribute the load throughout the subgrade under the surface.
Due to the differences in their composition, the durability of the two paving materials greatly varies. Asphalt is less durable. It needs a couple more layers to obtain the strength and thickness needed for ideal load distribution.
On the other hand, concrete is a highway-heavy material that doesn’t need such layered application to obtain ideal density since it’s naturally strong. Because of this, concrete provides a couple of distinct benefits that asphalt can’t boast.
While asphalt is extremely popular when it comes to paving, it isn’t the ideal material for the project in a lot of cases. Here are several reasons why you should choose concrete:
Unlike asphalt, concrete is completely recyclable. This makes it a more eco-friendly paving material.
Long-term Cost Savings
Concrete paving provides long-term cost savings compared to asphalt due to its low-maintenance nature and excellent lifespan. However, it might prove costly upfront.
Concrete paving tends to last a lot longer compared to asphalt even though it does not require a lot of maintenance. Concrete has an average lifespan of 2 to 4 decades. This depends on conditions and traffic.
Because it includes a more durable composition, concrete paving needs little-to-no maintenance in general compared to asphalt. Concrete helps keep a smooth flow of traffic by lowering property disruptions since large cracks and glaring potholes are less likely to develop.
Also, concrete paving offers a more comfortable working environment for people who work outdoors in hot weather. The reason for this is that concrete does not absorb heat. On the other hand, asphalt absorbs heat from the sun.
