PROBLEM TO BE SOLVED: To provide an asphalt mixture superior in strength and economic efficiency. SOLUTION: In this asphalt mixture, waste fluid sand produced from a fluidized bed-type burning boiler is mixed into 3-20% of aggregate. Preferably, the asphalt mixture contains 85 mass% or more of the waste fluid sand with a grain size of 5 mm or less, which allows all grains of the waste fluid sand to pass through a 10 mm sieve.
