If you just knew about the conventional hot mix asphalt, you should be aware of an emerging trend in asphalting. The warm mix version is gaining popularity with asphalt driveways. Since its invention, the warm mix asphalt takes a bigger share in the construction industry, both in commercial and residential sectors. If you consider using the warm mix for your asphalt driveways, you should know that the mixture takes a different process from the usual hot mix asphalt. From mixing to compaction, the process is different. The main objective of the mixture is to come up with a product that is less environmentally destructive.
In that regard, warm mix asphalt has low hydrocarbon emissions and fewer greenhouse gasses. Since it is low in temperature, it is safer even for the workers who install it. For this reason, many consumers are turning to ‘greener’ asphalt driveways.
Warm Mix Versus Hot Mix Asphalt
As mentioned earlier, there are differences between the regular hot mix asphalt and the warm mix version. The main differences arise from the production process of the two versions. For example:
- Warm mix asphalt is produced under lower temperatures (between 30 and 120 degrees Fahrenheit) than what hot mix asphalt requires.
- Warm mix asphalt uses less heat energy and fuel. This eventually reduces carbon footprint
- Warm mix asphalt takes more time to cool
The Cost of Warm Mix Asphalt
When it comes to pricing, warm mix version of asphalt costs higher than the conventional hot mix brand does. The cost is usually higher at the initial installation. Experts believe that on average, warm mix asphalt costs three or five dollars more per ton based on the additives that come with it.
On the other hand, the warm mix uses less fuel and can be installed faster than the hot mix version. In addition, warm mix asphalt is easier to transport than the hot mix asphalt. This makes more cost-effective.
Warm Mix Asphalt Improves Performance
Experts in asphalt services believe that the warm mix version is more efficient and flexible. It is suitable for various applications including residential or commercial asphalt services. It suits various purposes using different road thicknesses as well. Besides, it can tolerate heavy traffic, making it suitable for both freeways and highways.
Impact on Workers
Experts in asphalt Melbourne has today suggest that warm mix asphalt is safer for construction workers compared to hot mix asphalt. From its production to on-site application, the product is a healthier choice because it produces less smoke and fumes, which can result in respiratory complications.
Construction workers using hot mix asphalt are under serious threat as the product produces fumes and smokes, which are serious health hazards especially in poorly ventilated conditions.
Since warm mix asphalt has fewer emissions, it is suitable for use even in humid days when the air quality is poor. The hot mix asphalt cannot work effectively under such conditions. For that reason, workers can work steadily without interruption as would happen with the hot mix version.
