“…Then, 0%, 1%, 3%, 5% bio-oil were added into aged bitumen 40/50 penetration grade asphalt. When test temperature reached 155 ˚C, and then blended for 25 min by high shear mixer with a speed of 600rpm to achieve a homogeneous mixing state [4,8,10,11].…”

“…They must not just rely on traditional routes, but need ingenuity to develop new ideas to use and reuse resources in different ways, and to look for new solutions to old problems of high demand for liquid asphalt is increasing rapidly and petroleum oil reserves becoming depleted. [4].Researchers and pavement industries have been seeking of new technology and approaches to reduce the use of petroleum asphalt. Using alternative materials is one of the most effective and environmentally friendly ways to solve this problem.…”

Investigating the Feasibility of Using Jatropha Curcas Oil (JCO) as Bio Based Rejuvenator in Reclaimed Asphalt Pavement (RAP)

Abstract. Reclaimed asphalt pavement (RAP) usage has increased recently due to the decreasing supply of liquid asphalt and concerns over adverse health effects when making use of petroleum-based/chemical recycling agents which increased the need for bio-based recycling agents designed to return the RAP binder to its original state. The objective of this study is to investigate the possibility of using jatropha curcas oil (JCO), which is a non-edible oil (do not compete with the food chain) that cannot be used for nutritional purposes due to the presence of anti-nutritional factors, such as phorbol esters, as a bio-base rejuvenating agent for aged bitumen. The physical properties and storage stability of the bio-oil, original bitumen, aged bitumen and rejuvenated bitumen were measured. The results of the investigation indicated that the bio-oil have potential to rejuvenate aged bitumen to condition that resembled the original bitumen, the use of the bio-oil show benefits from both health and environmental perspectives. Also the rejuvenated bitumen was found to be very stable in term of storage.

“…Bio-materials that are used as binders in asphalt mixtures are termed "biobinders" and were defined by Peralta et al (1) as "asphalt binder alternatives made from any non-petroleum-based renewable resources, which should not rival any food material, and have environmental and economic benefits". The interest on using biobinders in pavement engineering has significantly grown over the last decades due to the increasing scarcity of raw materials and environmental concerns about the use of non-recoverable natural resources.…”

“…According to the literature, biobinders can be used in three different ways to decrease the demand for fossil fuel based bituminous binders: (1) as a bitumen modifier (< 10% bitumen replacement), (2) as a bitumen extender (25% to 75% bitumen replacement), and (3) as a direct alternative binder (100% replacement) (1)(2)(3). In this regard, there exist several studies using biobinders as bitumen modifiers (4)(5)(6)(7)(8) but less research can be found using them as total replacement of bituminous binders (9)(10)(11)(12).…”

ABSTRACT:The interest in using bio-materials in pavement engineering has grown significantly over the last decades due to environmental concerns about the use of non-recoverable natural resources. In this paper, biomaterials are used together with Reclaimed Asphalt (RA) to restore some of the properties of the aged bitumen present in mixtures with high RA content. For this purpose, two bio-materials are studied and compared to conventional and polymer modified bitumens. Blends of these materials with RA bitumen were produced and studied to simulate a 50% RA mixture. The rejuvenating effect of the two bio-materials on RA has been assessed and compared with the effect of the conventional binders. Apparent Molecular Weight Distribution of the samples (obtained by the δ-method) and different rheological parameters were used for this purpose. Results revealed the power of bio-materials to rejuvenate RA bitumen, showing their capability to be used as fresh binders in high-RA content mixtures. RESUMEN:Evaluación del efecto rejuvenecedor de bio-materiales sobre ligantes para mezclas con alto contenido de asfalto recuperado. El interés en la utilización de bio-materiales en ingeniería de pavimentos ha crecido significantemente en las últimas décadas debido a la conciencia ambiental sobre el uso de recursos naturales no renovables. En este artículo, se utilizan bio-materiales para recuperar las propiedades iniciales del betún envejecido presente en mezclas con alto contenido de asfalto reciclado (RA). Para ello, se ha estudiado y comparado el comportamiento de dos bio-materiales con betunes convencionales y betunes modificados con polímeros. Con este objetivo, se fabricaron mezclas de bio-materiales y betún reciclado simulando mezclas asfálticas con 50% de contenido de reciclado. El efecto rejuvenecedor de los bio-materiales se ha evaluado y comparado con el efecto rejuvenecedor de ligantes convencionales mediante el cálculo de las distribuciones de peso molecular aparente y diferentes pará-metro reológicos. Los resultados muestran el poder rejuvenecedor de los bio-materiales, poniendo de manifiesto su potencial para usarse como ligantes vírgenes en mezclas asfálticas con alto contenido de reciclado.

New binders are produced in order to reduce dependence on crude oil. This study aims to evaluate pyrolytic products and their blends with bitumen, as a possible substitution for bitumen. Bitumen of the penetration grade 70/100 was used as a matrix for the blends. Standard test were conducted in order to determine mechanical properties of the reference bitumen, pyrolytic products, and their blends. The results obtained during this study indicate that pyrolytic products can be used as a substitution for bitumen originating from crude oil or, in proper proportions, as an additive to that bitumen. Analiza mogućnosti primjene produkta pirolize kao zamjene za bitumen u asfaltnim mješavinama Nove vrste veziva se proizvode kako bi se smanjila upotreba sirove nafte. Ispitivanje je provedeno s ciljem analize proizvoda pirolitičkog spaljivanja i njegove mješavine s bitumenom, kao moguće zamjene za bitumen. Kao kontrolni bitumen korišten je cestograđevni bitumen 70/100. Uobičajenim ispitivanjima utvrđena su mehanička svojstva kontrolnog bitumena, proizvoda pirolize i njihovih mješavina. Rezultati ispitivanja pokazuju da se proizvod pirolize može primjenjivati kao zamjena za bitumen ili, u prikladnom omjeru, kao dodatak bitumenu.
