Decide between asphalt and concrete for your driveway

Specifically, asphalt is a chemical compound of hydrocarbons, sulfur, oxygen, and heat that is formed through the production process and the results of petroleum refining. Dependence on asphalt as a raw material for your driveway construction produces various kinds of asphalt mixtures. In contrast to rigid concrete, asphalt is a pavement material that is flexible and elastic. This is because the asphalt material has a stable melting point but has a low melting point.

In this article, we will discuss the pros and cons of asphalt and concrete as a consideration for making your driveway.

Asphalt

In general, asphalt is an environmentally friendly material that is used especially for pavement work. This means that the asphalt can be set to a certain temperature so that it can be melted easily during road construction. At the same time, asphalt has a low melting point that will not allow an already hardened road to melt back or deform under high temperatures. Asphalt functions as a binder and coating for the soil surface by mixing aggregate fractions at a certain temperature.

The pros of asphalt driveway

  • The road is smoother, smoother, and less bumpy so it is more comfortable to drive.
  • The black color of the asphalt affects the user’s psychology to be more calm and comfortable.
  • For use on roads with light traffic, asphalt road construction is easier than concrete roads.
  • The maintenance process is easier because it only remains to replace the damaged part of the asphalt road.

Cons of asphalt driveway

  • In low temperatures or areas that have high or moderate rainfall, the asphalt material will quickly experience damage due to the nature of asphalt that is not resistant to standing water. In addition, the asphalt surface will crack quickly at too cold temperatures.
  • At too high a temperature, the asphalt can also weaken the asphalt binder, reducing its adhesion. If in this condition the asphalt is given a heavy enough load, then the surface of the asphalt will be damaged quickly.
  • Depends on soil conditions. If the soil conditions are not good and uneven, it is necessary to first repair or level the area to be asphalt
  • Requires maintenance every 3-5 years
  • Requires a drainage system. To overcome the weakness of asphalt against standing water, it is necessary to construct a drainage channel beside the road asphalt.

Concrete

There are many reasons why concrete is preferred. Concrete as a road material has properties that are considered more beneficial. But of course, concrete also has drawbacks that make asphalt better than it.

Pros of concrete driveway

Concrete is relied on as road construction because it has many advantages. The following are some of them:

  • Concrete is very hard so it can withstand higher loads.
  • Concrete is more resistant to hot weather during the dry season. The road surface is stable because it does not experience expansion.
  • Concrete is also more resistant in the rainy season because it is water-resistant. The concrete road surface is not easily eroded by rainwater, including when the water stagnates or is flooded.
  • Because they are not easily damaged, concrete roads do not require intense maintenance. That means more efficient road maintenance costs.
  • With a suitable road thickness, concrete can be applied directly without creating a sub-foundation.
  • Concrete can also be used on weak ground without having to do pavement first.

Cons of concrete driveway

Behind the series of advantages of concrete properties, there are also disadvantages or weaknesses. Here are some of them:

  • The price of concrete is classified as slightly more expensive so that the cost of building roads is more expensive.
  • The color of the concrete is classified as monotonous so that it gives a boring impression to the user.
  • The color of the concrete also gives the impression of being dry and hot.
  • Concrete roads are constructed with a thickness of at least 20 cm above the land surface. This causes the road surface to be higher than the ground or house level along the side.
  • Construction of concrete roads is often not accompanied by drains or drains along the sides. This causes puddles and even floods.

Work on concrete roads must be strictly by standard procedures. Otherwise, the construction will fail. The work process must be closely monitored so that there are no procedural errors. The condition of the concrete must be completely dry when it starts to be used. If not, the concrete will crack until it breaks. Allow sufficient time for the concrete to dry naturally. Drying too fast also has the potential to cause cracks.

To prevent cracking, you can try to cover the concrete surface with a wet cloth. Another way is to use a special substance that is mixed when stirring the concrete. The casting process must be carried out by skilled workers to produce a perfect, flat, and not bumpy road shape.
