“…In addition, testing of the hot mix asphalt type with continuous graded wear (asphalt concrete wearing course, AC-WC) was also carried out with the aim of seeing the used of bioasbuton as a binder in hot asphalt mixtures (HMA). For the record, in addition to bioasbuton made from bioCS and bitumen of Asbuton B 50/30 which has been studied by Sihombing, 2021, this study also looks at the effect of bioasbuton from straw (bioST) on ASB bitumen [13].…”

“…Based on the description above, in order to optimize the use of BGA and reduce the use of petroleum asphalt as well as to utilize coconut shell waste which is very large in Indonesia, this study aims to analyze the potential of bioasbuton, namely a binder consisting of bioasphalt coconut shell (BioCS) and bitumen of Asbuton B 50/ 30 [13], as a HMA binder.…”

Hot mix asphalt (HMA) with buton granular asphalt has long been known in Indonesia with maximum use of 15%. With this dose, the use of binder asphalt Pen 60/70 is still needed. Bioasphalt is a fraction of bio-oil derived from biomass resulting from the pyrolysis process whose raw materials are coconut shells and straw. This study tries to determine whether the results of the pyrolysis of coconut shells (BioCS) and straw (BioST) can be categorized as bioasphalt. In addition, it also aims to analyze the potential of bioasbuton, namely a binder consisting of BioCS and bitumen of Asbuton B 50/30 (ASB) as a binder in the AC-WC HMA. From this study, it is known that the BioCS and BioST can be categorized as bioasphalt. The addition of bioasphalt to ASB bitumen can produce bioasbuton with different properties from the original asbuton. The addition of 6% BioCS or 8% BioST to ASB bitumen produces bioasbuton with relatively similar properties to Pen 60/70. The effect of BioCS on changes in rheological properties ASB bitumen is stronger than BioST. The use of bioasbuton made from 15% ASB (by weight of HMA) and 25% BioCS (by weight of ASB) can produce an AC-WC HMA which is equivalent to using pen 60/70. Bioasbuton can be used as an alternative binder to substitute the use of Pen 60/70 in HMA.

“…For additional investigation, functional groups were established and contrasted. In addition to the IR spectra, changes in the carbonyl group (C=O) and sulfoxide group (S=O) can also be used to determine whether an asphalt binder has been modified [36][37][38]. Carbonyl (-C=O) is represented by the band at 1700 cm -1 [39] and sulfoxide is represented by the band at 1030 cm -1 .…”

This research aims to utilize glycerin pitch waste as an alternative asphalt binder (extender) in Stone Mastic Asphalt (SMA) mixture. Glycerin pitch (GP) is a by-product from crude glycerol refining process from the palm oil oleochemical industry. The research method was carried out by testing the chemical and physical characteristics of GP by comparing it to pen 60/70, then testing based on asphalt binder rheology and asphalt concrete characteristics. ANOVA statistical test and Tukey-Kramer statistical grouping test were used to know the significant use of GP in SMA mixture. The variations of GP content tested to pen 60/70 were 0%, 15% and 25% by weight, then used as a binder for the SMA mixture which was tested under asphalt content (Pb) conditions based on Marshall characteristic, immersion index and drain down. The test results show that GP has the potential as an asphalt extender, with a maximum content of 22% by weight of asphalt binder or with a ratio of 1 GP: 4 pen 60/70. The characteristics of the SMA mixture using pen 60/70 and GP as asphalt binder extender, under conditions of Pb = 7% produce SMA mixture that meets the specification. Statistically, in stability characteristics of SMA, GP has a significant effect on SMA + 22% GP mixture. In the immersion index, the use of GP has a significant effect on all type of mixture, while in the draindown characteristics has significant effect on the SMA+0% GP mixture.

“…Al analizar el asfalto PEN 60/70, el asbustón y el bioasbutón siendo el asbustón con adición de aceite de cáscara de coco en dosis de 4%, 5%, 6%, 8% y 16% de asfalto, se consideró el 6% como contenido óptimo ya que aumenta el punto de reblandecimiento alcanzando 51 °C, 58.5 °C y 53.5 °C con 0.28, 0.50, 0.50 de desviación estándar para cada tipo de ligante en estado fresco mientras que en estado envejecido fueron 56 °C, 65 °C y 57 °C con desviación estándar de 0.11, 0.07 y 0.28, por ello el bioasbustón tiene mejores criterios de envejecimiento que el asbustón [75].…”

La ingeniería de pavimentos, busca con ahínco materiales no petrolíficos como sustituyentes/mejoradores del asfalto. La producción de bioasfalto con biomasa es la técnica más usual con beneficios económicos, sociales y medioambientales. Este documento tiene como objetivo realizar una revisión literaria del mejoramiento del asfalto con biomasa en subproductos de biocarbón o bioaceite. Se efectuó una revisión de 80 artículos científicos, los cuales estudiaron las propiedades convencionales y reológicas del asfalto con porcentajes óptimos de adición de biomodificadores, considerándolos como nuevas tecnologías en las construcciones viales. Los resultados muestran que la dosis y tipo del biomaterial influye mucho como modificador, dado que el rendimiento del bioasfalto a base de biomasa garantiza reacciones positivas con una mínina adición de 1% de aceite de palma hasta 100% de ceniza de madera como máximo. En conclusión, a mayor dosis de biomodificador a altas temperaturas mayor es la mejora en la viscosidad, estabilidad, grado de penetración, punto de reblandecimiento, resistencia a la tracción indirecta, módulo de resistencia, resistencia a la deformación, resistencia a la fatiga, resistencia al deslizamiento y resistencia a la humedad del asfalto, además de tener mejores condiciones de envejecimiento oxidativo, pues generalmente el ligante asfáltico es compatible con la mayoría de los biomateriales, siendo viable como fuente de energía renovable, sostenible y de calidad.
