“…The most common mechanical properties of hot-mix asphalt with RAP, e.g., stiffness, resistance to fatigue cracking and rutting, tend to be better or at least equal to the characteristics of a traditional mixture [8,59,88].…”

The use of recycled aggregates, manufactured from several by-products, to replace virgin aggregates in the production of pavement asphalt mixtures needs to be encouraged. Nevertheless, there are some concerns and uncertainties about the actual environmental, economic and mechanical performance resulting from the incorporation of recycled aggregates in asphalt mixtures. Therefore, this paper has the goal of discussing important features to help decision makers to select recycled aggregates as raw materials for asphalt mixtures. Based on the literature review carried out and the own previous experience of the authors, the article's main findings reveal that incorporating some of the most common recycled aggregates into asphalt mixtures is feasible, even in a life-cycle analysis perspective. Although some specific technical operations are sometimes necessary when using recycled aggregates in asphalt mixtures, some benefits in terms of environmental impacts, energy use and costs are likely to be achieved, as well as in what concerns the mechanical performance of the asphalt mixtures.

“…Recycling of asphalt pavements is a technology developed to rehabilitate and/or replace pavement structures suffering from permanent deformation and evident structural damage. In this context, according to Reyes-Ortiz et al 2012 [9], the reclaimed asphalt pavement (RAP) is one of the most recycled materials in the world. The first data documented on the use of RAP for the construction of new roads dated back to 1915 [10].…”

“…RAP is considered to be one of the most important types of green asphalt pavement that minimizes environmental impacts through the reduction of energy consumption, natural resources and associated emissions while meeting all performance conditions and standards. In pursuit of sustainable development principles, sustainable development is defined as meeting the needs of the present without compromising the ability of future generations to meet their own needs [9] [11].…”

The durability potential of bituminous mixtures may be defined as the resistance of the mixture to the continuous and combined damaging effects of water. High durability potential usually implies that the mechanical behavior of the mixture will endure for a long service life. Now, flexible pavement, made of hot-mix asphalt (HMA) with the addition of the reclaimed asphalt pavement granules in the central asphalt mixing plant, is increasingly used. The amount of the added reclaimed asphalt pavement (RAP) depends on mineral materials and their homogeneity. This paper presents the physical properties of RAP and their influence on the durability performance of a binder asphalt pavement mix. A series of binder mixes containing varying percentages of RAP were designed and subjected to different moisture conditioning periods (1, 3 and 7 days) to investigate the moisture damage effect on RAP mixtures. A mix made from only virgin material was selected as the control mix. The effect of RAP on the durability of binder course mix was evaluated through a series of laboratory tests including Marshall test, indirect tensile strength test and the water sensitivity tests where many moisture damage indicators were obtained such as retained Marshall stability, Marshall quotient, durability index, tensile strength ratio, resilient modulus ratio and energy loss ratio. The results indicated that the additional of RAP especially at 50% content was beneficial in improving the durability performance and reducing the moisture susceptibility of the hot mix asphalt mixtures.

“…On the other hand, besides wanting to decrease the temperature in the production of bituminous mixtures, it is also intended that these are reusable (Reyes-Ortiz et al, 2012). The resources that make the mixtures, aggregates and binder, are natural and therefore limited.…”
