A resposta correta é a alternativa "c) Ambas as afirmações estão corretas". O objetivo do teste RTFOT (Rolling Thin Film Oven Test) é simular o envelhecimento do ligante durante a mistura e compactação da mistura (envelhecimento de curto prazo). O envelhecimento é causado pela oxidação e evaporação do ligante em ação contínua.
