How do we determine the amount of Aphalt in a mix? The process of determining the amount of Aphalt in a mixture begins with the extraction of moisture. This can be done using a laboratory-grade abrasive blast machine or by reheating samples in a microwave oven. The temperature of the sample must not exceed 110 C, and the amount of moisture extracted should be subtracted from the asphalt content reading to get an accurate reading.
Asphalt is 100 percent recyclable. In the U.S. alone, 82.2 million tons of RAP were recycled into new mixes in 2018. In 2018, RAP made up 21 percent of the total asphalt mix in the U.S., and the combined weight of everything we recycle each year in the United States was approximately 68 percent of the total amount of asphalt industry recycling. It is also highly sustainable. In addition to recycling, asphalt has the potential to be used for a variety of construction purposes.
To produce asphalt mixtures with a low carbon footprint, warm-mix technology is used. This process lowers the temperature of the asphalt mixture while increasing productivity. The method also minimizes exposure to fumes, odors, and fuel emissions. Since the process is so efficient, warm-mix asphalt is the most widely used type of asphalt in the U.S. Today, it accounts for 40% of the market. Although warm-mix asphalt is more expensive than cold-mix asphalt, it is more environmentally friendly and has the potential to reduce the energy usage of asphalt-based pavements.
