Description
Z. L. Abo-Shanab leads a 2026 study that changes waste polystyrene so it can improve bitumen, the sticky binder in asphalt. Plain polystyrene is stiff and low in polarity, so it mixes poorly and stores badly. The team grafted acrylic acid onto it, then reacted it with an amine to make a new form.
Tests confirmed the new groups were added, and the changed polymer bonded well with bitumen through hydrogen bonds. At 7 percent by weight, storage stability was much better than with plain polystyrene, and elastic recovery rose from 25 percent to 55 percent. Resistance to rutting also improved, raising the grade from 70 to 76.
