“…During the last years, research within the civil engineering sector has focused on the use of the C&D waste as new construction materials for bases, sub-bases and firms. Among these studies, Poon and Chan (2006), Aatheesan et al (2008), Courard et al (2010), and Kuo et al (2010) can be highlighted. In addition, other specific works using C&D waste in railway projects include research works by Helsen et al (1998), Indraratna and Salim (2003) and Krezel et al (2004).…”

In the last years, the European Union (EU) has been focused on the reduction of construction and demolition (C&D) waste. Specifically, in 2006, Spain generated roughly 47million tons of C&D waste, of which only 13.6% was recycled. This situation has lead to the drawing up of many regulations on C&D waste during the past years forcing EU countries to include new measures for waste prevention and recycling. Among these measures, the mandatory obligation to quantify the C&D waste expected to be originated during a construction project is mandated. However, limited data is available on civil engineering projects. Therefore, the aim of this research study is to improve C&D waste management in railway projects, by developing a model for C&D waste quantification. For this purpose, we develop two equations which estimate in advance the amount, both in weight and volume, of the C&D waste likely to be generated in railway construction projects, including the category of C&D waste generated for the entire project.

“…In this regard, in order to contribute to sustainable development, several studies have been conducted dealing with the use of recycled concrete aggregates (RCA) from CDW as aggregate in hot-mix asphalt (HMA) (Cho et al, 2011;Kuo et al, 2010;Lee et al, 2012;Chen and Wong, 2013;Motter et al, 2015;Mills-Beale and You, 2010;Paranavithana and Mohajerani, 2006;Pasandín and Pérez, 2013, 2014Pérez et al, 2007 and2010;Pérez et al, 2012a;Pérez et al, 2012b;Shen and Du, 2004;Shen and Du, 2005;Tam et al, 2007).…”

“…Particularly, several studies have indicated that HMA mixes made with RCA have higher moisture damage resistance than those made with natural aggregates (Mills-Beale and You, 2010;Paranavithana and Mohajerani, 2006;Pérez, 2013 and2014;Pérez et al, 2007 and2010;Pérez et al, 2012a;Pérez et al, 2012b).…”

The incorporation of recycled concrete aggregates (RCA) from construction and demolition waste (CDW) in hot-mix asphalt (HMA) could be a way to promote sustainable construction. This paper describes a laboratory study on the use of RCA in HMA for base courses in pavements. HMA involving RCA in percentages of 0%, 5%, 10%, 20% and 30% were evaluated. To improve the moisture damage resistance of HMA made with RCA, the mixtures were cured in the oven for four hours at a mixing temperature of 170ºC, before compaction. The results indicated that the mixes made with RCA and cured for four hours in the oven loosely comply with Spanish moisture damage specifications. The results also indicated that the Marshall Stability and the moisture damage resistance are substantially improved by curing the mixture in the oven. The mixtures also exhibited an adequate resistance to permanent deformation. The results from this study were highly encouraging, although HMA with RCA requires further investigation.

The civil engineering sector has to assume among its aims the reduction of the construction and demolition waste generated by it. To this end, foreseeing the amount of construction and demolition waste to be generated, as well as the time phase in which they might be produced, will allow for planning good environmental practices on site, both in a general way-for all the waste-as for each individual category of waste. The aim of this research paper is to determine the major categories of construction and demolition waste produced in railway construction works, and the construction stages where they are mainly generated. At the same time, a Best Practices Manual including a relation of best practices for on-site waste management is proposed and could be included in the Internal Quality System of the companies. Results of this study show that establishing and implementing a Best Practices Manual in engineering works for the phases of construction of tunnels, preliminary works and ground movement involves the management and minimization of almost 95% of the total waste generated. In addition, integrating the Report and Management Plan of construction and demolition waste together with the Best Practices Manual, promotes the environmental management of the company, favouring the cohesion of the construction process organization at all stages giving rise to establishing responsibilities in the field of waste and providing a greater control over the process.
