Improving durability of asphalt mixes produced with reclaimed asphalt pavement (RAP) by enhancing binder blending

道路建设行业通过使用沥青粘合剂与石油行业紧密相连。然而，沥青粘合剂的价格与原油价格挂钩，近年来价格波动较大。回收沥青路面创造了一个重复使用材料的循环，优化了自然资源的使用，如原始骨料和粘合剂。再生沥青路面（RAP）是一种可持续的替代原生材料，因为它减少了生产沥青路面混合料所需的昂贵的新沥青结合料和原生骨料的数量。因此，在沥青混合料中使用RAP正在成为加拿大沥青铺路行业的常见做法。然而，用RAP生产的沥青混合料的耐久性仍然是一个重大挑战。因此，本研究建议的主要目标是研究可能的解决方案，以提高沥青混合料与RAP的性能，增加RAP的老化和添加的处女粘合剂之间的混合。

The road construction industry is strongly linked to the petroleum industry through the use of asphalt binders. However, the price of asphalt binder is linked to the price of crude oil and high volatility has been seen in prices in recent years. Recycling asphalt pavement creates a cycle of reusing materials that optimizes the use of natural resources, such as virgin aggregates and binders. Reclaimed asphalt pavement (RAP) is a sustainable alternative to virgin materials because it reduces the amount of costly new asphalt binders and virgin aggregates required in the production of asphalt paving mixtures. Thus, the use of RAP in asphalt mixes is becoming a common practice by the asphalt paving industry in Canada. However, the durability of asphalt mixtures produced with RAP remains a major challenge. Hence, the main objective of this research proposal is to investigate possible solutions to enhance the performance of asphalt mixes with RAP by increasing the blending between RAP's aged and added virgin binders in the mix.
