Durability of concrete containing Recycled Asphalt Pavement (RAP)

As the world moves towards new sustainable solutions, the use of recycled materials in concrete, whether it is for roads, structural or non-structural uses, becomes more indispensable. The aim of the study is to give an overview on Recycled Asphalt Pavement (RAP), a reclaimed material resulting from the milling of road/motorway surfaces. While different studies exist regarding the effect of RAP on the mechanical properties of concrete, limited research is available on the durability of concrete containing RAP. This paper presents a review of methods currently used to study durability aspects of RAP concrete in different applications, such as moisture, permeability, freeze-thaw, etc. and the open issues that need to be further investigated.
