“…Although RAP was derived always from the same stockpile obtained from the cold milling the same pavement, RAP Management (fractionating, stockpile management practices, etc. ), material heterogeneity (RAP Asphalt Content & Gradation) and other sources of variations caused RAP variability [23][24][25][26][27][28]. Despite this, it is noted that due to the use of a very high percentage of RAP, experiments demonstrate that the solutions proposed meet a number of sustainability requirements [29][30][31].…”

The goal of this paper is to investigate transportation infrastructure sustainability from a wider standpoint.A sustainable transportation infrastructure can be defined as a safe, efficient, economic, environmentally friendly infrastructure meeting the needs of presentday users without compromising those of future generations. This concept involves environmental, economic and societal aspects.In more detail, as for a road, a sustainable infrastructure or pavement must comply with environmental, economic and social requirements.Unfortunately, even if a definition of a sustainable pavement for urban or suburban areas can be easily proposed, the proposal of practical strategies to really pursue sustainability goals is sometimes disregarded in favour of emphatic announces of not well defined sustainable solutions.In the light of the above facts, the sustainability of a transportation infrastructure based on the actual environmental, social and economic characteristics is discussed in this paper. Once the main factors which can influence infrastructure sustainability are assessed, an analysis is performed in order to set out practical strategies for pursuing the main objective.Finally an experimental investigation is designed and carried out in order to assess porous asphalt value in terms of pavement sustainability. The tests carried out are promising about the possibility of achieving suitable levels of overall performance. Practical applications and perspectives in rehabilitation, maintenance, and research are outlined.

“…Thus, rates higher than 50% were used in binder and base courses along the Fenix Project (Valdés, Martínez, & Pérez-Jiménez, 2008). The results obtained led to the conclusion that both the Marshall stability and granulometric variability tend to grow as new RAP is incorporated.…”

This paper presents the performance of different types of asphalt mixtures containing reclaimed asphalt pavement (RAP) and industrial by-products such as cupola furnace slags and green sands. In this study, conventional bitumen is employed as binding material while limestone is used as natural aggregate. The Marshall method has been used for designing the asphalt mixtures and voids percentage while water sensitivity and wheel tracking tests have been carried out to evaluate the mixtures performance. Although the only natural aggregate is limestone, and this significantly hinders the performance of these mixtures, laboratory results show that they can be successfully employed in the construction of low traffic intensity roads as binder course.Key words: RAP, cupola slag, green sand, asphalt concrete, bituminous mixture. ResumenEste artículo recoge el rendimiento de diferentes tipos de hormigón bituminoso fabricados con material fresado y residuos industriales: escoria de horno de cubilote y arenas verdes de moldeo. El árido natural empleado es calizo y el ligante es un betún convencional 50/70. Las dosificaciones se han realizado utilizando el método Marshall, los ensayos mecánicos efectuados sobre las mezclas son los requeridos por la normativa española: porcentaje de huecos, sensibilidad al agua y ensayo de rodadura. Aunque la utilización de caliza como único árido natural penaliza el rendimiento de estas mezclas, los resultados han mostrado que pueden llegar a ser viables para capas intermedias de pavimentos de baja intensidad de tráfico.Palabras clave: Material fresado, escoria de cubilote, arenas verdes de moldeo, hormigón bituminoso, mezcla bituminosa.
