The decrease of crude oil availability, typically used to produce asphalt binders, is a concern among the pavement materials researchers. Binders from alternative sources have been studied as total or partial replacement of asphalt binder in asphalt mixtures more intensively in the past decade. However, the characterisation of these new materials, in order to determine how their properties affect the mixture performance, remains a challenge. This paper presents a comparison between one neat asphalt binder and a bio-binder from renewable resource (for 100% replacement of the asphalt binder), in terms of the linear viscoelastic characterisation, permanent deformation susceptibility, fatigue resistance and thermo-gravimetric characterisation. Results show that the bio-binder studied presents similar behaviour in terms of stiffness and permanent deformation susceptibility to the neat asphalt binder, that was taken as the reference for wearing course pavement layer application. Nevertheless, in terms of fatigue life, the bio-binder showed lower performance.

通常用于生产沥青结合料的原油供应量下降是路面材料研究人员关注的一个问题。在过去的十年中，已经研究了替代来源的粘合剂，作为沥青混合物中沥青粘合剂的全部或部分替代品。然而，为了确定它们的性能如何影响混合物性能，表征这些新材料仍然是一个挑战。本文就线性粘弹性表征，永久变形敏感性，抗疲劳性和热重表征，对一种纯沥青粘合剂与可再生资源生物粘合剂（以100％替代沥青粘合剂）进行了比较。结果表明，所研究的生物粘结剂在刚度和对纯沥青粘结剂的永久变形敏感性方面表现出相似的行为，这被用作耐磨层铺面层应用的参考。然而，就疲劳寿命而言，该生物粘合剂表现出较低的性能。
