Understanding the Various Types of Asphalt Pavements and Their Uses

When it comes to paving a road or parking lot, have you ever considered the type of asphalt you are going to use? There are different types of asphalt available, each designed for specific purposes and climates.

Asphalt pavement is the most common type of pavement used today due to its durability, ease of installation, and low maintenance.

It is used in various applications such as roadway surfacing, airport runways, parking lots, and driveways. With so many types of asphalt to choose from, it can be challenging to understand which one is best suited for your project.

When planning a paving project, one of the essential decisions you will make is the type of asphalt to use. Each type of asphalt offers different strengths and weaknesses, so it’s crucial to make an informed decision.

Big Easy Asphalt will provide an overview of the different types of asphalt paving available to help you choose the right one for your project.

Types of Asphalt

There are many different types of asphalt, each with its own unique properties and uses. The most common type of asphalt is hot mix asphalt, which is used to pave roads and highways. This type of asphalt is made by heating a mixture of aggregate and asphalt binder to a high temperature, then laying it down and allowing it to cool and harden.

Hot Mix Asphalt (HMA)

One of the most common types of asphalt used in New Orleans is Hot Mix Asphalt (HMA). This type of asphalt is made by heating a mixture of aggregates (such as crushed stone, sand, and gravel) and bitumen (a sticky, black, and highly viscous liquid or semi-solid form of petroleum) to high temperatures.

The resulting mixture is then transported to the construction site and laid down in layers with a paver. HMA has several advantages over other types of asphalt, including high durability, resistance to temperature fluctuations and rutting, and a smooth finish.

Warm Mix Asphalt (WMA)

In the city of New Orleans, the most common type of asphalt used in road construction is Warm Mix Asphalt (WMA).

This type of asphalt differs from traditional Hot Mix Asphalt (HMA) in that it is manufactured at lower temperatures, typically between 30 and 120 degrees Fahrenheit.

This lower temperature results in reduced emissions and decreased fuel consumption during production, making it a more environmentally friendly option.

Cold-Mix Asphalt (CMA)

In New Orleans, one of the types of asphalt used is Cold-mix Asphalt (CMA). This is an asphalt mix that contains a lower percentage of bitumen than hot-mix asphalt (HMA), making it easier to work with and apply.

CMA is used in situations where hot-mix asphalt is not readily available or practical and is commonly used for repairs of potholes, utility trenches, and other small to medium-sized paving projects.

CMA is also known for its ability to set quickly and withstand low temperatures, which is important in areas with colder climates. Despite its advantages, CMA does have some limitations, such as lower durability and resistance to heavy traffic, making it unsuitable for high-traffic roads and highways.

Porous Asphalt

One of the types of asphalt used in New Orleans is porous asphalt. Porous asphalt is a type of pavement that is designed to allow water to flow through it and into the ground, rather than running off into storm drains or overflowing into nearby bodies of water.

It is made up of a mix of coarse aggregate, fine aggregate, and bituminous binder, which creates a porous structure that allows water to pass through.

This type of asphalt is especially useful in areas prone to heavy rainfall or flooding, as it can help prevent stormwater runoff and reduce the risk of localized flooding.

Dense-Graded Mixes

In New Orleans, the most commonly used type of asphalt is a dense-graded mix. Dense-graded asphalt is a combination of fine and coarse aggregates, along with a binder material, which is typically asphalt cement.

This type of asphalt is known for its smooth texture, durability, and resistance to wear and tear. Dense-graded asphalt is often used in areas with high traffic volumes, such as highways and major roads, as it can withstand heavy loads and constant usage.

Quiet Pavement

Quiet pavement is a type of asphalt that is designed to reduce noise pollution from vehicle traffic. It is made up of a porous mix of asphalt and aggregates, which allows water to drain through it and makes it quieter than traditional asphalt. Quiet pavement is used in many cities, including New Orleans, as a way to reduce traffic noise in urban areas.

The Types of Asphalt That Are Best for Driveways

asphalt pavingWhen it comes to choosing the best type of asphalt for driveways, there are two options to consider: hot mix asphalt (HMA) and cold mix asphalt (CMA).

HMA is the more commonly used type, as it is durable and lasts longer than CMA.

It is made of a mixture of stone, sand, and asphalt cement, and is typically used for high-traffic areas. On the other hand, CMA is more flexible and easier to work with, making it ideal for smaller projects or for repairing smaller cracks in driveways.

It is made of a mixture of asphalt emulsion and aggregate and does not need to be heated before application. Ultimately, the best type of asphalt for a driveway will depend on factors such as climate, the amount of traffic, and the desired lifespan of the driveway.

Difference Between Type A and Type B Asphalt

Type A asphalt is a dense-graded asphalt pavement used mainly for highways and airports that receive high traffic volumes. Its aggregates are close to each other, making it less porous and more durable.

Type B asphalt, on the other hand, is an open-graded asphalt pavement used primarily for low-volume roads and parking lots. Its aggregates are farther apart, making it more porous and allowing for better drainage.

Type B asphalt is also known for its noise-reducing properties compared to Type A asphalt. While both types of asphalt serve different purposes, they both consist of a mixture of asphalt binder and aggregates, and proper placement and maintenance are important factors in ensuring long-lasting pavement.
