Study of Highway Coarse Aggregate Gradation on Airport Pavement Concrete Design
This paper chose 5~31.5 mm coarse aggregate (commonly used in highway) to supersede 5~20 mm, 20~40 mm double-graded coarse aggregate (commonly used in airport pavement), studying the influence of 5~31.5 mm coarse aggregate on the airport pavement concrete. The results show that the flexural strength and loss rate of relative dynamic elastic modulus of airport pavement concrete prepared with 5~31.5 mm coarse aggregate meet the airport pavement design requirement, the optimum mix amount is the water-cement ratio of 0.40 and the unit cement consumption of 330 kg/m3, and for frost resistance durability after 200 freeze-thaw cycles, the relative dynamic elastic modulus is still above 90%.
