Description
Weishuai Ji, Shuangshuang Liang, and Wenyuan Xu explain a trade-off in straw-based asphalt in a 2025 study. Oil from liquefied straw residue can partly replace petroleum binder in roads, but how the two blend at the molecular level was murky. Computer simulations met bench tests to find out.
Simulations showed hydrogen bonds between the straw oil and asphalt growing with dose, peaking at ten percent, where the tightest molecular network formed. Road tests confirmed a split effect: the blend resisted high-temperature rutting better after short aging, yet cracked more easily in the cold after long aging. The best dose, they conclude, depends on climate and road demands.
