Anyone who has spent time traveling on the road knows how common it is to see construction sites on the road. It may seem like a hassle to drive through the sites, but the roadwork is a necessary means of fixing problem areas to make the road safer to drive on. There are a few different methods that are commonly used for fixing roads, which vary depending on the type of issues and the type of road.
Roads that experience a heavy amount of traffic are prone to cracking over time. It can lead to issues with travelers if the cracks become deep or wide enough. If the cracks aren't repaired quickly, it can be a more extensive and expensive project. Cracks are typically repaired by sealing them. This consists of the construction workers cutting the road around the cracks to the required depth, cleaning the cracks using air pressure, and pouring a crack sealant into the cracks. A dusting of sand is applied to the sealant to reduce the amount of stickiness and protect the sealant while it dries.
Sometimes a road just needs to be rejuvenated due to normal wear and tear. The process is used to protect streets that have been paved recently and extend the life of the road. The road is rejuvenated by thoroughly cleaning the road, applying a treatment on the surface, and covering the entire road with sand for 24 hours to allow the treatment to seal itself. The next day the sand is removed using a street sweeper.
When a road is constructed out of asphalt, it will need to be resurfaced when it reaches the end of its service life, which is estimated to be 8 to 12 years. The method is used when other repair methods will no longer suffice. It is a long process that begins with lowering the utilities under the road so they are not damaged during the project. Then the construction workers must remove the old asphalt and then once again raise the utilities so they are in the proper place once the new road is laid. The construction workers will then lay out the new asphalt, pave it so it is smooth, and apply the proper treatments on the road.
There are many other types of road repair methods, such as infrared repair or for sealing. The methods are typically chosen due to the degree of damage and what may be more cost effective for the county or state that is handling the repairs. Many projects are also on a deadline, especially for roads that experience high amounts of traffic and require full use of the roads due to safety and efficiency.
