Hi When you say appositive, I understand that as "adjective" or "adjectival phrase". However, your word is OK In English, the appositives in a phrase are usually placed before the noun, separated by commas (but without a comma before the noun): Tim, while riding his red, rusty, old bike down the road, saw a spoon. You might use semicolons if you wanted dramatic effect: Tim was riding his bike: it was red; it was seriously rusty; it was old.
