Upheaval buckling or blowup of concrete pavements due to high environment temperature is a serious problem in transportation infrastructure which quite often leads to road failure or even traffic hazards. The proposed project presents a combined theoretical, numerical and experimental investigation on the effective enhancement of thermal buckling capacity of pavement slabs with or without initial imperfection by using light and green functionally graded concrete materials with reduced usage of plain Portland cements for less carbon dioxide emissions. The research outcomes will contribute significantly to the society by offering a novel environmental friendly pavement solution with greatly improved road safety.

由于高环境温度而引起的混凝土人行道的动荡屈曲或炸毁是运输基础设施的严重问题，这通常会导致道路故障甚至交通危险。提出的项目提出了一项合并的理论，数值和实验研究，以通过使用光和绿色功能分级的混凝土材料，并使用较少的碳二氧化物发射的纯波特兰水泥使用降低普通波特兰水泥，从而有效地增强了具有或不具有初始不完美的路面板的热屈曲能力。研究结果将通过提供新颖的环境友好的路面解决方案，并大大提高道路安全性，从而为社会做出重大贡献。
