Description
Road crews can recycle old asphalt in place by heating and reusing it, a green method whose surface can still age and crack. Yao Guan and co-authors studied that aging in 2024, exposing recycled mixes to heat with oxygen and to a year of ultraviolet light in the lab. They tracked strength at high and low temperatures and resistance to water damage.
Aging bought little gain in heat strength, while crack resistance fell sharply. Ten years of heat aging cost far more bending room than the year of light exposure. The team built a formula to forecast the decline and proposed measures of how far light aging has gone. They urge stronger anti aging steps for recycled roads.
