“…As seen in Table 2, several studies concluded that mixtures using RCA generally meet the national specifications for water resistance [38][39][40]48,51,52,54]. Many of these studies qualify this finding by stating that the resistance to the action of water decreases with an increasing percentage of RCA [40,48,51]; therefore, for percentages of RCA over 75%, the specifications are not met [45].…”

“…However, Pasandín and Pérez [44] reported that curing a mixture of RCA for 4 h in an oven did not significantly affect the Marshall stability. Despite the variety of reported results, a common key conclusion can be extracted from the literature review: the bituminous mixtures using RCA generally meet the national Marshall stability and flow specifications [28,[30][31][32][33]36,48,[51][52][53]. Therefore, these mixtures will have a sufficient capacity to withstand traffic loads.…”

h i g h l i g h t sRecycled concrete aggregates (RCA) have poor quality than natural aggregates. A review on the properties of hot-mix asphalt (HMA) with RCA is conducted. Most studies report a high stripping potential of these mixtures. Several treatments help mitigate its unsatisfactory moisture damage resistance. Test stretches of HMA with RCA exhibited good performance. a b s t r a c tRecycled concrete aggregates (RCA) appear to be suitable materials to use in hot-mix asphalt (HMA) for flexible road pavements. However, the poor quality of RCA results in different engineering properties of an HMA using RCA compared to mixtures composed of natural aggregates. This paper presents a review on the properties of HMA with RCA. Varied laboratory results were obtained, likely because of the heterogeneous nature and origin of the RCA. Nevertheless, a majority of the studies report a high stripping potential of RCA mixtures. Several treatments help mitigate this problem. Additionally, select test stretches of the RCA mixture exhibited good performance.

“…The hazardous wastes list is available as per the European Regulation [6][7][8][9]. Inert CDW can be processed and made suitable for use in road construction, e.g., [10][11][12][13][14]. Other research studies have clearly suggested the possibility of properly treating and reusing such waste as aggregate in new concrete (especially lower level applications) [15][16][17][18][19][20][21][22][23][24][25].…”

Demolition wastes may be used in different civil engineering applications as road constructions, concrete, and embankments or landfill. Regardless its application, leaching tests of the waste should be carried out to assess concentrations of pollutants. Concrete, brick and mixture of concrete, bricks, tiles and ceramics wastes were subject to percolation test-CEN/TS 14405, and batch test-SR EN 12457. The leachates were analyzed with respect to concentration of inorganic elements-arsenic, barium, cadmium, chromium, copper, mercury, molybdenum, nickel, lead, selenium, zinc, fluoride, chloride and sulfate, and organic compounds (phenol index). The concentrations of elements in leachates were compared with the limit values of European regulation for the acceptance of inert wastes at landfills. Generally, the releases of inorganic species in leachates were below limits values. Some waste leachates obtained by percolation and batch test had high values for phenol index.

“…have been recycled and reused in some applications. Similarly, the reuse of recyclable materials has been under study for many years through technological work and research on the environmental impact of such practices [4][5][6][7][8][9]. The recycling of industrial waste in civil engineering applications has remarkable potential in the long term.…”

Owing to the large amount of waste slags produced by zinc industry, it has become necessary to recycle it in some areas. Road construction has significant potential for the use of waste materials because more material is always needed. In this study, the engineering behaviour of asphalt concrete was investigated using mineral aggregates with waste slag, which is a by-product of the zinc-lead production industry. The asphalt concrete tested in this study was fabricated using 25, 50, 75 and 100 % mixing ratios instead of the conventional fine mineral aggregate (11, 22, 33 and 44 % rate of total aggregate mixture) to determine the possibility of using slags in the binder course of bituminous hot mixtures. The asphalt concretes, made of waste slags and conventional asphalt concrete, were evaluated in terms of their fundamental engineering properties such as Marshall stability, flow, Marshall quotient (MQ), bulk specific gravity, air voids and voids filled with bitumen in the total mix characteristics. The results indicate that the addition of waste slag as mineral aggregate improves the engineering characteristic performance and that it can be used in bituminous hot mixtures. In addition, principal component analyses were applied to examine the significance of each Marshall parameter, and a regression model was developed to estimate the MQ value using effective parameters.
