Streets, roads, highways, and freeways connect every corner of the country. We use them ever single day, whether it is just taking the kids to school or visiting family across the country. So, there are few types of construction which are quite as important to us all as roads. But before any good asphalt company can head out and start laying the paving, there is a necessary level subgrade excavation which needs to take place beforehand. Known as subgrade preparation, this is an essential service for any new roads and one, which you want to be sure that you are getting from your best local team of professionals. Fortunately for you, at Orlando Excavating Pros, we have supported excavation needs throughout Florida and we would no doubt be able to do the same for you too. Simply share your plans with us and we can collaborate on delivering the most effective subgrade service.
What is the Subgrade?
The subgrade is the most important part of any successfully constructed roadway. Directly below the road material itself, it is essentially the foundation for the structure and so, it should go without saying that it is crucial for a lasting installation. Made up of the native soil of the area, it is the product of a properly excavated and leveled piece of land. It is of vital importance that it be sufficiently compacted, so that it is dense and stable enough to maintain both the installation of the asphalt and the ongoing stress of vehicles driving over it.
The first step when integrating a new road into a landscape is to remove the natural material and topsoil from the space. From foliage to rough dirt, every last thing in the way needs to be fully removed and relocated. This requires an able earthmoving tool and a consistent level of precision, for the entire process. Our team knows how to do this best and so, we can assure you of the most effective topsoil excavation with ease.
Following on from this, we will need to make sure that the excavated area is left smooth and level along the entire course, if the road is to be installed properly. That is why all of the loose topsoil needs to be compacted and evened out, making use of the appropriate roller. Our team understands the need for precision and consistency during this part of the process and we make sure that we are delivering no less than the very best every time.
In just about every case of roadway installation, particularly in areas of loose or moist ground, it will be necessary to add strength to the land. This can be done by introducing aggregate to the space, which will form a sturdy layer between the subgrade and the road. Known as the subbase, the vast majority of drivable roads use these today and you should no doubt be doing the same, yourself. Again, this will be sufficiently compacted so that it is stable enough to support the asphalt and will no doubt be a reliable way to install your road.
