Asphalt is a widely used paving material for commercial surfaces such as parking lots, driveways, and roads. It is known for its durability, longevity, and cost-effectiveness. However, not all types of asphalt are created equal, and choosing the right one for your commercial project is crucial. This blog discusses the different types of asphalt and which one is best suited for commercial use.
1. Hot Mix Asphalt (HMA):
HMA is the most commonly used type of asphalt for commercial paving. It is made by heating a mixture of asphalt cement and aggregates that include stone, sand, and gravel to a high temperature. HMA is known for its durability and ability to withstand heavy traffic loads, making it the go-to choice for highways, airports, and industrial areas.
2. Warm Mix Asphalt (WMA):
WMA is a newer type of asphalt that is gaining popularity in the commercial paving industry. It is produced at a lower temperature than HMA, which reduces fuel consumption and harmful emissions. WMA is also more workable than HMA, making it easier to apply and compact. WMA is an ideal choice for areas with light to medium traffic.
3. Porous Asphalt:
Porous asphalt is a type of HMA that is designed to allow water to pass through it, which reduces runoff and improves drainage. It is ideal for areas prone to flooding and helps prevent water damage to pavement and structures. Porous asphalt is frequently employed for surfacing parking lots, driveways, and walkways. It offers excellent permeability, allowing water to drain through easily, reducing runoff, and promoting eco-friendly practices.
4. Perpetual Pavement:
Perpetual pavement is a type of asphalt that is known for its long-term durability and low maintenance. It is made up of multiple layers of HMA with an underlying layer of flexible asphalt and an overlying layer of rut-resistant asphalt.
5. Stone Matrix Asphalt (SMA):
SMA is a specialized type of asphalt that includes a higher-than-normal percentage of crushed stones, making it highly resistant to rutting and cracking. SMA is ideal for high-stress areas such as areas with tight turning radii or areas with heavy truck traffic. SMA is also a highly durable choice for parking lots and driveways that are exposed to harsh weather conditions.
Choosing the right type of asphalt for your commercial paving project is crucial to ensure durability, longevity, and cost-effectiveness. When evaluating options, it's crucial to carefully weigh factors such as traffic load, location, weather conditions, and maintenance needs. These considerations play a vital role in making an informed decision. Consult a professional commercial paving company such as D & E Construction Co Inc to determine which type of asphalt is best suited for your project.
