Evaluation of Carnauba waxes in warm mix asphalt technology
Feitosa, Johnny Peter Macedo; Alencar, Ana Ellen Valentim de; Souza, José Roberto Rodrigues de; Soares, Jorge Barbosa; Soares, Sandra de AguiarCarnauba wax (CW) is a natural product which is being evaluated as a warm mix additive in order to reduce energy consumption and pollution emissions levels. The effect of adding three different types of natural carnauba waxes to asphalt cement 50/70 was investigated with the purpose of evaluating their potential as warm mix additives. Rheological tests were carried out using a rotational viscometer and a dynami...
