- PublicaciónAcceso abiertoEvaluación del comportamiento del asfalto modificado con cenizas de cascarilla de arroz(Universidad de Ibagué, 2018) Parra Bechara, María Camila; Gallo Ortiz, Julian Camilo; Salazar Susunaga, María PaulaThe present investigation was carried out in order to present the analysis of the evaluation of the behavior of modified asphalt with rice husk ash (RHA). Said study was carried out using five different modifying ash percentages (4, 4.5, 5, 5.5, 6), where each one of them underwent diverse tests; Softening point, rotational viscometer, Stripping adhesion, specific gravity, tray adhesion and penetration, obtaining a total number of 144 laboratory tests. With the results obtained, a characterization of its properties was carried out in order to compare the modified asphalts with the conventional asphalt, determining that the RHA improves the mechanical and rheological properties of the bituminous agent.
