Why Use Asphalt for Road Construction?
Asphalt is a mixture of aggregate, sand, additives and bitumen. It is one of the most popular types of construction material used in road and pavement installations. With roots dating back to the 1870s, it has been a vital element in various structural development and construction.
Even though concrete remains to be the most commonly used component for building, a lot of paving contractors and plant hire companies in Australia and other countries prefer to use asphalt in some of their installation projects. With the continuous surge in the popularity of asphalt, it is not surprising that it is slowly knocking off concrete as the most preferred choice for roads, parking lots and pavement installation projects.
A major factor that contributes to the recognition of asphalt is the advantageous features that it has to offer. Riddled with many beneficial properties, it is a promising building component for roadwork and similar construction schemes.
Asphalt constructed roads, pavements and parking lots are said to have a lifespan of almost 15 to 20 years, even longer if maintained properly. Compared to concrete, which can only last 10 to 15 years even with regular maintenance and repairs, it is understandable why it is slowly becoming a favourite.
Easy to Install
Asphalt projects can be completed in half the time it takes for a full construction using other types of materials to finish. Also, asphalt installations dry out a lot faster. Newly installed asphalt can be used as early as 24 hours after completion.
Compared to other types of construction materials, asphalt does not require a hefty budget to be installed. It is cheaper than most of the materials used for road construction.
The best redeeming quality of asphalt is that it is 100% recyclable. A recent statistical study shows that it is among the most recycled materials all over the U.S. The best part is that recycled asphalt is said to be a lot thicker and stronger than new asphalt mixture.
Recently, a new variation called “green asphalt” has been introduced to the market. This is a type of asphalt mixture that has a lower carbon footprint. Although it has just been launched, some states have already put it in the list in the qualifications for green tax credit merits.
Easy to Maintain
Unlike concrete that has to be completely removed and replaced once it shows signs of severe cracking, asphalt can easily be repaired in a number of ways. One option is to resurface the damaged area alone through crack filling or overlaying.
Another is by isolating the damaged area and repairing it through milling or patching. But regardless of the method used in maintenance repairs, it is apparent that costs of maintenance procedures and necessary repairs are significantly lower than that of concrete.
After thorough deliberation, it is safe to say that asphalt holds a lot of potential. This is why it is not surprising at all that professionals prefer using it to other kinds of construction materials. Judging from the benefits that it has to offer, it is expected to grow further in popularity in future years to come.
