Understanding the Different Types of Asphalt Installation

Asphalt paving is an excellent option for a cost-effective and durable driveway, walkway or parking lot for homeowners and businesses alike. However, not all asphalt is created equal. Understanding the various types of asphalt installation can help you make an informed decision about which option is best suited for your project. In this blog post, we'll take a closer look at different types of asphalt installation methods, outlining their benefits and limitations.

Hot Mix Asphalt (HMA)

Hot mix asphalt (HMA) is the most commonly used asphalt installation method. Mixing a combination of hot asphalt cement and aggregates, this method provides a strong, durable, and long-lasting surface. It's perfect for high traffic areas, driveways, and parking lots as it can stand up to heavy loads and extreme weather conditions. One of the benefits of HMA is that it is flexible and can withstand heavy loads, avoiding cracks and potholes.

Warm Mix Asphalt (WMA)

Warm mix asphalt (WMA) is similar to HMA but with a lower temperature of mixing, hence the name. This lower temperature reduces emissions, saves energy, and reduces the amount of fossil fuels needed. WMA is environmentally-friendly, and its lower mixing temperature also allows contractors to work longer hours, leading to quicker turnover times.

Porous Asphalt

Porous asphalt is a popular choice for public spaces and environmentally conscious homeowners. This method involves the use of asphalt that allows water to drain through it, preventing pooling and erosion. The porous surface also provides a better surface for pedestrians and reduces the risk of slipping. The reduced need for drainage systems and stormwater management also makes porous asphalt a popular choice in urban design.

Perpetual Pavement

Perpetual pavement involves using a layer of flexible HMA, followed by a layer of strong aggregate and topped with another layer of HMA. This three-layer approach creates a long-lasting surface that can last for up to 50 years with proper maintenance. The bottom layer remains flexible, providing strength and preventing cracks and potholes from forming.

Thin Asphalt Overlays

Thin asphalt overlays (TAOs) are ideal for low to moderately-trafficked areas such as residential driveways, parking lots, and cul-de-sacs. Its cost-efficiency and ability to provide a smooth final surface make it an excellent choice for retaining existing traffic patterns while providing a new surface.
