Types of Asphalt Paving
Asphalt paving is the bee’s knees for homeowners and contractors in NYC due to its durability, cost-effectiveness, and ease of installation.
Different asphalt types, each with its own advantages and features, are available for residential and commercial projects in NYC.
Let’s dive into some common types of asphalt used for residential and commercial projects.
Hot Mix Asphalt (HMA)
Hot Mix Asphalt, or HMA, is the most commonly used type of asphalt in NYC.
It’s a mixture of aggregate materials like sand, gravel, or crushed stone combined with liquid asphalt cement at high temperatures.
This creates a flexible yet strong surface that can withstand heavy traffic loads and harsh weather conditions.
Porous Asphalt
Porous asphalt is an environmentally friendly option designed to allow water to drain through the pavement instead of pooling on top.
This reduces stormwater runoff while also providing better traction during wet weather conditions.
Porous asphalt is often used for parking lots or low-traffic areas where proper drainage is essential.
Cold Mix Asphalt (CMA)
Cold Mix Asphalt, or CMA, differs from hot mix because it’s mixed at lower temperatures using emulsified binders rather than traditional hot bitumen binders.
CMA has excellent workability properties making it ideal for temporary repairs, patching potholes, and other small-scale projects.
However, it’s not as durable as hot mix asphalt and is typically used for temporary fixes.
Warm Mix Asphalt (WMA)
Warm Mix Asphalt, or WMA, is a more environmentally friendly alternative to HMA.
It requires less energy to produce because it’s mixed at lower temperatures than traditional hot mix asphalt.
This results in reduced greenhouse gas emissions during production and installation.
WMA also offers better workability properties compared to HMA while maintaining similar performance characteristics.
Stone Matrix Asphalt (SMA)
Stone Matrix Asphalt, or SMA, is a high-performance type of asphalt designed for heavy traffic loads such as highways and major roads.
Its unique structure features a dense matrix of coarse aggregates held together by a strong binder system that provides excellent resistance against rutting and cracking.
Asphalt paving is a popular choice in NYC due to its durability, cost-effectiveness, and ease of installation. There are several types available including Hot Mix Asphalt (HMA), Porous Asphalt, Cold Mix Asphalt (CMA), Warm Mix Asphalt (WMA) and Stone Matrix Asphalt (SMA). Each type has unique characteristics and benefits suitable for different projects such as temporary repairs or heavy traffic loads on highways.

- Preliminary Work: Create a stable base by removing old pavement, excavating soil if needed, grading the ground level appropriately, and compacting it using specialized equipment.
- Budget Estimation: Create a budget estimate for your project, considering materials, labor costs, and permit fees.
For optimal results, plan the project for a time when temperatures are consistently above 50°F (10°C) and there is minimal precipitation forecasted.
Working with experienced professionals who specialize in asphalt paving projects is highly recommended to ensure top-quality results every step of the way.
Installation Process
Installing asphalt paving in NYC requires careful planning and execution to ensure a durable and long-lasting surface.
Site Inspection
Before starting any work, conduct a thorough site inspection to identify any potential issues that may affect the project’s success.
Grading and Excavation
Remove existing pavement or soil to create a stable base for the new asphalt surface, ensuring proper grading to prevent water damage.
Base Material Installation
- Aggregate: Place a layer of crushed stone on top of the graded area to provide additional support for heavy loads.
- Compaction: Compact the aggregate base using specialized equipment to prevent future settling or shifting.
- Fabric Interlayer: Install an optional fabric interlayer between layers of HMA to improve bonding strength.
Asphalt Paving Application
Spread hot mix asphalt evenly over the prepared base using specialized paving machines and compact it with rollers for a smooth and even surface.
Joint Sealing
Seal any joints or seams between sections with hot rubberized crack sealant to prevent water infiltration that can lead to premature deterioration.
Final Inspection and Cleanup
Conduct a final inspection to ensure all work meets quality standards and perform necessary cleanup before your new asphalt surface is ready for use.
