Two different bioasphalt are used, which is bioasphalt from coconut shell and bioasphalt bitutechRAP, aged asphalt is extracted from Recycled Asphalt Pavement (RAP) taken from Karawang, West Java, and the original asphalt as a control is pen 60/70 from Pertamina. The samples were made by mixing each bioasphalt on aged asphalt at 7 different percentage of 2%, 4%, 8%, 16%, 20%, 25%, 30%, then each samples tested the penetration and softening point of asphalt (referring to control asphalt properties), to get the optimum percentage of bioasphalt. Samples with optimum bioasphalt then tested with FTIR for chemical structure and SEM for morphology. The results of this study are (1) the percentage optimum of bioasphalt as rejuvenator, which is 23% for bioasphalt coconut shell and 17% for bioasphalt bitutechRAP; (2) the addition of bioasphalt to aged asphalt shows that the morphological conditions, chemical structure and rheology of asphalt are almost close to the new asphalt condition; (3) bioasphalt are potencially as rejuvenator.[/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]Coconut shells,Recycled asphalt pavement,Softening points,West javas[/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][/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/10.1088/1757-899X/508/1/012041[/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]
