In fact, in the U.S. alone, 39% of roads are considered to be in poor or mediocre condition. The primary culprit behind substandard roadway conditions: potholes.

TRANSCRIPT FROM VIDEO: Asphalt mixes incorporating RAP should be evaluated for key performance specifications. To do this, samples from the fractionated RAP stockpiles are taken to a lab for analysis. Determining the amount of RAP viable in a balanced mix design will depend on the established mix specifications. Typically, by using a blend from different fractionated particle [...]
Traditional methods and materials for roadway development may be here to stay, but the advent of sustainably produced additives that may support contractor and department of transportation goals to lower their carbon emissions are much newer to the industry. Newer still is the perspective that asphalt and bitumen additives can be produced with a lower carbon footprint, helping [...]
TRANSCRIPT FROM VIDEO: To recycle RAP into new roadway surfaces as an eco-friendly alternative, the material must be processed into a more uniform product.
