What Stone, Concrete & Asphalt Means in Site Development
When we’re talking about stone, concrete, and asphalt, we’re talking about the foundation of a project’s infrastructure. These three materials work together to form a solid foundation. When you choose Wynn Site Development, we take care of all three of these areas, so you don’t need to hire multiple contractors.
Stone is the Aggregate Base
Stone is necessary to prevent the site from sinking or shifting. Stone in these instances refers to aggregate base. Crushed stone is compacted on the soil to create a stable platform. Large, fractured stones are placed along slopes to slow down rushing stormwater and prevent soil erosion.
The Strength of Concrete
Concrete is used for its high compressive strength and durability. Since it does not move, it is used in areas that experience extreme weight and high friction. This is why you often see it used in sidewalks and roads.
Asphalt & Its Flexibility
Asphalt is a blend of stone aggregates bound together by a sticky, petroleum-based liquid asphalt cement. It is quick to install and more cost-effective over large areas than concrete. This is why it is often used in parking lots and highway connectors.
Aggregate and Stone Base Work
Aggregate and stone base work are extremely important in site development. It serves as the basic building blocks.
The stone base under North Carolina roads is aggregate base course, otherwise known as ABC stone.
Proper aggregate and stone base work builds a solid foundation beneath roads, driveways, and parking lots. It also works to prevent erosion and promotes good drainage.
Concrete Work: Curb, Gutter, Sidewalk, and Pads
When we talk about concrete work in site development, we’re referring to curbs and gutters, sidewalks, and building pads. This work is vital and needs to be done with precision and care.
In curb-and-gutter systems, the concrete is often poured at the same time. Curbs are necessary because without them, road edges will quickly unravel and spill into the street. Meanwhile, the gutter collects runoff from the parking lot and directs it toward storm sewers and catch basins.
Sidewalk construction must also be precise, as it requires grading that complies with accessibility laws. Concrete pads also need to be solid enough to withstand the weight of garbage trucks and other heavy equipment. Wynn Site Development has the expertise needed to get the job done.
Asphalt Preparation and Coordination
At Wynn Site Development, we work to grade the compacted sub-base finely. This is an important role because a thin or uneven base is susceptible to premature cracking and rutting under North Carolina’s warm temperatures.
Besides asphalt preparation, it is also necessary to consider other aspects of the site. At Wynn Site Development, we ensure that all concrete curbs and gutters are fully cured and backfilled before paving begins. We also look to see that anywhere the area between where the new asphalt meets the existing pavement is properly treated.
We check weather reports to make sure that Mother Nature will cooperate when the project is slated. Paving requires a dry surface and specific ambient temperatures. If a sudden rainstorm hits, the paving must stop. Laying hot asphalt on a wet base traps steam, which strips the liquid asphalt from the stone. You can count on our team to plan accordingly so this does not happen.
Sub-Base Quality: Proof-Rolling and Undercut
If you don’t want your project to fail, you can’t skip the proof-rolling process. Before paving, a loaded truck must run over the area to check for soft spots. If any are found, that is a red flag for unsuitable soil that needs to be undercut and stabilized. Many contractors forget this step, leading to pavement failure early.
At Wynn Site Development, you can count on us to ensure this step is handled so you don’t have to worry. We know how important it is to your project, which is why it is important to us.
