Asphalt is a well-known and versatile material for construction. Although there are various asphalt surfacing options depending on your specific construction job. With that in mind, let's dig deeper into the different types of asphalt surfacing and when to use them in construction.
You can also contact asphalt contractors in Auckland to help you find the ideal asphalt type for your project. Let's get to it.
1. Hot mix asphalt
Hot mix asphalt involves pouring heated asphalt at about 150°C. Asphalt contractors in Auckland often consider hot mix asphalt for its versatility, impermeability, and weather resistance. Contractors use this asphalt type in areas with temperatures exceeding four Celsius to prevent the mix from quickly cooling down.
2. Warm mix asphalt
Suppliers produce warm mix asphalt similarly to hot mix asphalt. However, warm mix asphalt involves pouring at a lower temperature.
Suppliers add binders and additives to warm the asphalt mix, making it easier to pour and spread at a lower temperature. On top of that, warm mix asphalt is more energy efficient than hot mix asphalt since it takes less energy to produce and releases fewer fumes. Hence, this asphalt surfacing is suitable for sites with inadequate air circulation.
Warm mix has the same flexible and durable properties as hot mix asphalt. Uses for warm mix asphalt include road surfacing, driveways, and various commercial and residential construction.
3. Cold mix asphalt
Cold mix asphalt surfacing requires no heating but takes time to harden and cure. As a result, the surfacing may be pliable and have a shorter life span. Cold mix asphalt surfacing is suitable for extreme freezing temperatures when hot mix asphalt is not applicable. Cold mix asphalt is usually a temporary fix for cracks and potholes while waiting for a permanent solution.
4. Porous asphalt
Porous asphalt has small holes extensive enough to let water pass through them. Thus, this type of asphalt surfacing is ideal for flood-prone areas. Porous asphalt allows water to drain into the asphalt and reach the soil or stone bed.
This asphalt type is also durable and heavy-duty. Installing the porous asphalt mix does not require special tools or equipment. Therefore, asphalt contractors in Auckland can install porous asphalt as they would with other paving projects.
5. Dense-graded asphalt
Dense-graded asphalt is a type of hot mix asphalt that uses densely packed fine or coarse-graded aggregate. Manufacturers mix and pour these materials to create a dense and impenetrable layer. Dense-graded asphalt is an all-weather asphalt type that can withstand various traffic conditions.
The asphalt surfacing type you use will highly depend on the conditions of the area and the type of construction project in progress. You'll discover that hot mix asphalt is the most common among the asphalt types listed above.
Once you've found the most suitable asphalt surfacing mix, you can reach asphalt contractors in Auckland. These contractors will provide the best equipment for asphalt paving and help you apply asphaltic concrete on your construction site.
