An international team of engineers has built an asphalt that can withstand oil spills and save lives, researchers say.
A team of researchers from the University of Wisconsin-Madison, the University at Buffalo, and the University in Bremen built the new asphalt based on their own experience with asphalt used in the US military.
The research team’s project was published in the journal Materials Letters.
The researchers said the new material was superior to the typical asphalt used for oil spills in that it is more resistant to cracking and cracking from the impact of an impact, and it’s easier to maintain.
The new asphalt, which has a density of about 15 percent, is made up of two layers: a porous, flexible polymer called PEG (polyethylene glycol), and a porous and flexible composite called a “solution.””PEG-based asphalt has the same strength and stiffness as asphalt, but with a higher density of PEG,” the researchers said.
“This allows it to withstand greater impacts, as well as being stronger and more durable.”
“Solutions can be used to replace conventional asphalt, and there is no difference in performance or durability,” the team said.
The team said they tested the asphalt on two different types of oil spills: a single-stage spill, in which there is a single vehicle, and a larger-scale spill, which can result in a whole tank of oil.
“Sixty-two cars and one tanker filled with oil spilled during the two spill types, with all vehicles experiencing cracks, punctures, and dents,” the group said.
A few weeks after the first spill, the researchers compared the new solution to existing asphalt in an effort to understand the new technology’s durability.
The study showed that the new PEG-backed asphalt is not susceptible to cracking or punctures when subjected to the impact forces of a single, large-scale oil spill.”PRECISE-based tests showed that a single impact could break the PEG solution, and that there is little evidence of cracking or damage to the polymer layer,” the study said.
“However, in multiple impacts, we observed that the polymer layers, which are more prone to cracking, were weakened, even though there was no significant difference in the strength of the polymer at any point during testing,” the authors said.
While the team’s asphalt could not be used for the military, the study also showed that PEG can be recycled.
“For oil spills, it is critical that there are alternatives that can be produced from petroleum products that are durable and resistant to crack, damage, and cracking,” the investigators said.
