This study aims to compare the resilient modulus and dynamic modulus of asphalt mixture using RAP material. A series of laboratory test has been conducted to three mixtures were tested using UMATTA and AMPT respectively, one mixture of completely virgin material and the other two consist of 20% and 30% of RAP material. The resilient modulus is based on any loading form with rest period, while the dynamic modulus is derived from a sinusoidal or haversine loading with no rest period. The result of resilient modulus and dynamic modulus test showed that the mixtures incorporating with RAP material have a better value compared to the mixture with virgin material. The resilient modulus and dynamic modulus can be compared by converting loading time of resilient modulus to angular frequency of dynamic modulus and the predicted dynamic modulus in particular frequency can be determined by using fitting parameter of master curve. A plot of average dynamic modulus versus average resilient modulus then being developed. The result showed that resilient modulus value is almost 1.4 times of the predicted dynamic modulus.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Angular frequencies,Dynamic moduli,Dynamic modulus tests,Fitting parameters,Master curve,Permanent deformations,Resilient modulus,Virgin materials[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Dynamic modulus,Master curve,RAP,Resilient modulus[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.3850/978-981-11-0449-7-064-cd[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
