Recycled Asphalt Cost

A hot mix costs $78/ton. Therefore, the saving is phenomenal at $60/ton. Hence, if a person uses 50 tons of asphalt for 30 days, he could save up to $90,000. These are absolute profits. Asphalt recycling also reduces oil consumption, mining, and quarrying and the potential costs associated with these activities.
