摘要

In this paper, the influence of fly ash with different dosage and grades on the crack performance of airport pavement concrete was studied. Its exercise new Dumbbell Test Method could make the airport pavement concrete material be tested accurately and quickly during early-age from pouring. The effect of fly ash with different grades and dosage on volume stability of airport pavement concrete was evaluated by Dumbbell Test Method. Also the paper analyzes the mechanism of the influence of fly ash on the crack performance of airport pavement concrete.
