I would guess about 70-80 bales
It depends how thick the gravel is being laid - at 4 inches thick, a cubic yard will cover 81 square feet.
1 (cubic yard) = 46 656 cubic inchesIf the depth is 2 inches then the area it will cover is 46656/2 square inches = 23,328 square inches. Convert 23,328 square inches to square yards23 328 (square inches) = 18 square yards
5 ft by 9 ft is 45 square feet. This requires 6,480 square inches to cover it.
You have not said what substance you are using a ton of to cover the asphalt.

Assuming a standard bale size of 14 inches high by 18 inches wide by 36 inches long, and assuming the bales are only one layer deep, 90 bales would cover a little over 400 square feet.
It will depend on the size of the bale. Bales come in different sizes, but most will cover somewhere between 20 square feet to 120 square feet at about 2.5 to 3 inches deep. Ask that question when purchasing your bales since the size does vary considerably and some bales are machined compressed and some are hand compressed. For that reason, just looking at a bale and comparing the sizes does not always tell you how many square feet a particular bale will cover.
An acre is 43,560 square feet. Most small square bales would lightly cover at least 2x10 ft, but more likely 2x15 ft . Therefore; 43,560 divided by 30 (if each square bale covers 30 sq/ft as an average) = 1,452 square bales. If the bales are larger (round bales), obviously fewer bales would be required. Large round bales would likely provide at least 10X the coverage so likely in the range of 145 round bales
If those are inches, the area is 143 square inches.
Each tile covers 81 square inches. You have 1,296 square inches to cover. It will take 16 tiles to cover that area.

80 inches squared to just cover it
Three square feet would cover one square yard or 36 square inches.
