“…The use of RAP have increase remarkably, this in turn has led to an increase in demand of rejuvenators. [5,6].Bio resources researchers and pavement engineers have investigated a range of different bio oils such as waste cooking oil, waste engine oil as rejuvenating agents designed to return the RAP binder to its original state [7]. The result of the investigation indicate that by utilizing waste engine oil (WEO) and waste cooking oil (WCO) as rejuvenating agents have revive the aged bitumen to a condition that resembles 60/70 and 80/100 penetration grade bitumen respectively [8,9].…”

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.

Resumo: As Misturas Asfálticas de Módulo Elevado, do francês Enrobé à Module Élevé (EME), são constituídas por um Cimento Asfáltico de Petróleo (CAP) de baixa penetração e por agregados que compõem uma curva granulométrica densa, proporcionando as mesmas elevada resistência à deformação permanente e ao cisalhamento. As Misturas Asfálticas Recicladas a Quente (MARQ), com incorporação de elevado percentual de fresado, ou Reclaimed Asphalt Pavement (RAP), apresentam grande potencial de uso como material alternativo para a técnica mencionada (EME). Sua viabilidade é dada pelo fato de que o CAP oxidado, presente nessas misturas asfálticas, apresenta maior rigidez, além da vantagem relativa ao uso de uma matéria-prima de custo inferior a partir da reciclagem considerando elevados percentuais de uso da mesma. Este trabalho apresenta um estudo sobre o potencial de utilização de diferentes MARQ com incorporação de elevado percentual de fresado como camada de base e de ligação em pavimentos asfálticos, quais sejam: (i) Mistura I, composta exclusivamente por RAP como agregado; (ii) Mistura II, composta por 75% de RAP e 25% de agregados naturais; (iii) Mistura III, composta por 75% de RAP e 25% de agregados do tipo refugo de usina de asfalto. Desta maneira, além da caracterização destes materiais em laboratório, foram realizadas análises computacionais, baseadas no Método dos Elementos Finitos (MEF). Os valores dos deslocamentos, das deformações e das tensões obtidos para diferentes estruturas de pavimentos asfálticos compostos por essas misturas foram avaliados a partir do dimensionamento de estruturas e, a partir disso, o tráfego que essas estruturas eram capazes de suportar foi calculado. Os resultados mostraram que as MARQ constituídas por elevado percentual de fresado podem compor estruturas utilizadas em rodovias de tráfego médio e alto.Palavras-chave: reciclagem, alto percentual de fresado, refugo de usina de asfalto, misturas asfálticas de módulo elevado, dimensionamento de pavimentos. Abstract:The high modulus asphalt mixtures (EME) are constituted by an asphalt binder of low penetration and aggregates that have a dense grading curve providing high resistance to permanent deformation and shear stresses. The recycled hot mixtures asphalt (RHMA) with the incorporation of high percentage of reclaimed asphalt pavement (RAP) have potential for the use as an alternative material for the mentioned technique (EME). Its viability is given by the fact that the RAP oxidized binder has higher stiffness (low penetration), and also by the economy that can be achieve with the use of raw material from recycling with potential lower cost. This paper presents a study of the potential use of different RHMA with high percentages of RAP as a base and intermediate course of pavements, such as: (i) Mixture I, composed exclusively by RAP as aggregate; (ii) Mixture II, composed by 75% of RAP and 25% of natural aggregates; (iii) Mixture III, composed by 75% of RAP and 25% of asphalt plant refuse aggregates. Thus, besides the characterizatio...
