Description
Zahra Rasouli, Mehdi Mehdinazar, and Gholam Hossein Hamedi study how water that runs off roads helps crack asphalt, and how a lime based additive at tiny scale can fight back. Wet runoff wears at the glue that holds the mix together, and dirt in the water can make it acid or alkaline.
The team mixed two stone types and two grades of bitumen, with two doses of the additive. Lab tests measured stiffness, crack growth, and the surface energy that drives bonding. Wet terms, above all acid ones, cut the energy that holds stone and bitumen apart. The mix lost a fifth of its toughness in such terms.
