Asphalt Paving in Arlington, Texas
In simple terms, asphalt paving means covering up of driveways, streets, and highways with asphalt. Asphalt is an organic product, a crude oil derivative (also refers to as bitumen) used for paving.
Asphalt is a mixture comprises of bitumen and stone aggregates such as gravels, granite, and stone sands are used. The role of bitumen in paving is to bind stones aggregates tightly together and to enhance its tensile stress, this helps to withstand heavy weight without the stones moving out of place.
Is there a difference between asphalt and blacktop?
Both asphalt and blacktop are terms confusing to a lot of people probably because blacktop is a variety of asphalt and the questions keep surfacing in an attempt to find the right answers.
Are you curious about the differences that exist between the two (asphalt and blacktop)? If you are reading this right now, you are definitely in the right place at the right time and it’s high time your curiosity is met with deserving answers.
Though asphalt and blacktop are used for road construction purposes, the first differences lie in the composition of stones contained. The two main components found in the two are bitumen and a mixture of stones, which are in a larger amount in blacktop compare to asphalt. This explains why asphalt offers a better smooth surface in comparison to the blacktop.
Also, asphalt is easy to pour and becomes readily available for cars and vehicles with a minimum of two days after road construction, while blacktop is not that easy to pour and needs more days to dry up better. Asphalt offers a better black appearance compares to blacktop and maintenance is much easier during winter, because asphalt is a good absorbent of heat which helps to melt ice and snow quickly during winter.
Asphalt is used in busy roads such as major city streets and highways, unlike blacktop that is used in less busy areas such as residential and driveways. Asphalt is more durable, easier to maintain, and produces lesser wear effects on tires due to its smooth surface.
How many years does an asphalt driveway last?
Normally, an asphalt driveway should last a minimum of 10 years. The life expectancy of an asphalt depends and its determination by some important factors;
Asphalt type used is the first important factor that will determine how long it will take it to last. For asphalt to last long it should contain finely mixed aggregate, with enough bitumen to hold it in place, therefore, during the construction of a driveway, an asphalt of high quality should be used.
Having an asphalt of high quality is not enough if it’s not well-installed. During the construction of a driveway, the road should be prepared in such a way that it prevents the accumulation of rainfall and snows on the surface which gradually opens it up for relocation of water beneath it. When this happens, the asphalt loses its strength. Another important point to note is to ensure all debris is removed and the road is properly sand-filled before applying asphalt.
The climate's condition of an area affects the lifespan of asphalt. The consequence of extreme temperature on asphalt is seen as cracking and loosening of the surface.
Lack of policy to guide and prevents the heavy truck from parking for a long time on the driveway and against oil spillage which affects bitumen efficiency to hold aggregate mixture intact.
How long does it take for asphalt to fully cure?
You should not mix up asphalt cure for drying. Though, vehicles and trunks can be permitted to move on asphalt after a few days of application (this is called asphalt drying) but does not mean it has been fully cured.
The duration for which asphalt is fully cured requires at least six months or more and within this period, the asphalt is susceptible to damage because it has not yet attained its full capability, therefore, it should be properly managed and maintained. No heavy vehicles should be allowed to park on a spot for days, as this can deform the surface of the asphalt and allow water pooling which further damages it.
