The correct answer is: A. Shale powder.

Shale powder is a type of filler that is used in plastic bitumen. It is a fine, dry powder that is made from shale, which is a type of sedimentary rock. Shale powder is used in plastic bitumen to improve its properties, such as its strength, durability, and water resistance.

Talc powder is another type of filler that is sometimes used in plastic bitumen. However, talc powder is not as effective as shale powder at improving the properties of plastic bitumen. Asbestos powder is a type of filler that should never be used in plastic bitumen. Asbestos is a dangerous material that can cause cancer. Plastic powder is not a type of filler that is used in plastic bitumen.
