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.

混凝土路面在高温环境下的起拱或爆裂是交通基础设施中的一个严重问题，常常会导致道路故障甚至交通事故。建议的项目提出了一个综合的理论，数值和实验研究的有效提高路面板的热屈曲能力，或没有初始缺陷，使用轻和绿色功能梯度混凝土材料，减少使用普通波特兰水泥，减少二氧化碳排放量。研究成果将为社会提供一种新型的环境友好型路面解决方案，大大提高道路安全性。
