GOOD SUBGRADES FOR ASPHALT PAVING

With most of the world now using motorized vehicles to move products, people and livestock from one place to the next the asphalt industry has an obligation to provide strong, smooth, attractive options for vehicles to move safely and comfortably to get the job done.

When planning an asphalt surface, the thickness of the surface is determined by the quantity and quality of the subgrade materials. Asphalt surfaces are typically built up by a layered system of various materials and each layer contributes to the overall strength and function of the structure. Most parking lots and pavements in Denver are built on a smooth foundation of native subgrade soils with a dense, graded aggregate forming the working platform for the asphalt paving materials to be laid. When the placement and compaction of the soil and aggregate layers, two or more layers of asphalt are added to complete the asphalt surface. These two layers usually consist of an asphalt base layer and an asphalt surface layer.


Another important factor to be taken into account is good surface drainage and good subgrade drainage. Laying the rock so that the water can reach out and not gather in low areas, causing puddles and eventually potholes.

Designing and building new pavement systems requires a thorough understanding of the soils, rocks, and drainage that will go into the foundation of the asphalt pavement or driveway. If all these factors are correctly taken into account, you will have a strong, durable, good looking asphalt surface that will last for many years.
