“…The experimental facet of this study emphasized instrumentation monitoring, to investigate the structure's response and validate the derived numerical models. In addition to the re-use of end-of-life tyres, pollution to the environment and fire risk issues were also addressed (Hennebert et al, 2014). This paper presents the real-scale impact experiments conducted in this study and addresses the impact response of the embankment under different impact energies.…”

Abstract. This paper addresses the response of rockfall protection embankments when exposed to a rock impact. For this purpose, real-scale impact experiments were conducted with impact energies ranging from 200 to 2200 kJ. The structure was composed of a 4 m high cellular wall leaned against a levee. The wall was a double-layer sandwich made from gabion cages filled with either stones or a sand-schreddedtyre mixture. For the first time, sensors were placed in different locations within the structure to measure real-time accelerations and displacements. The test conditions, measurement methods and results are presented in detail. The structure's response is discussed in a descriptive and phenomenological approach and compared with previous real-scale experiments on other types of embankments.

“…Composition of tires includes 21% of carbon black and 0-15% of silica and particles are emitted by tire wear and found in road runoff water and sedimented in road storm basin [23]. Shredded tires mixed with crushed limestone (to be used as fill material in embankment) did not release particles during a one year-lysimeter study [24]. A second group are ENPs of the synthetic organic pigments (referred in the colour index C.I.…”

Environmental assessment of engineered nanoparticles (ENPs) currently suffers from lack of data on production, emission, behaviour and fate in natural compartments. This paper aims to bring factual data on production amounts of ENPs and emission of mineral elements in a colloidal or nanoparticulate forms stemming from products, (e.g. cosmetics, paints, concretes) and from two potential waste sinks, namely municipal sewage sludge and nonhazardous waste landfill sludge. Based on the declaration of production and importation of ENPs in France in 2014, we set out a classification of ENPs substances comprising carbon black, organic pigments, miscellaneous organic substances and mineral ENPs. These mineral ENPs were sub-classified on the basis of production and CLP ecotoxicological and hazard classifications. Major elements (Group #1) encompass ENPs substances ubiquitous in total contents, and also as a colloid fraction in waste leachates (Si, Ca, Ti, Al, Mg, Fe, Mn, P). Minor elements were divided as ENPs with soluble substances and dissolved metal ions non-classified as ecotoxic (Group #2: Ba, Bi, Cr (III), Sr, Zr, La, Pd, Mo, W, Y, Au) or with soluble substances classified as ecotoxic and hazard statement code in the CLP regulation (Group #3: Ce, Cu, Zn, Ni, Sb, Ag, Co). Paints, concrete and particularly cosmetics proved to be sources of ENPs. Colloidal forms of elements or ENPs were found in leachate obtained from paint (Si), in cosmetics leachates (Al, Si, Ti and Zn), and in one demolition concrete (Ti). No nanoparticulate forms or fraction of Ag, Ce, Ti and Zn were identified by TEM/EDS in municipal sewage sludge. However, sewage sludge could be a sink for Group #3 elements such as Ag and Ce, since their total concentrations were significant. Based on landfill leachates from municipal solid wastes, the colloidal fraction frequently contained elements of Group #3 (Ni, Zn, Cu, Co and Sb) but with low mean concentration and more rarely Ag and Ce, indicating that the fluxes of these elements from the landfill cells should be low, except for Ce. Landfills seem to not emit ENPs in their leachates. From a regulative aspect, monitoring of Ag in sewage sludge for agricultural use could be of concern.

“…Hennebert et al (2014) reported that tire rubber only had limited consequences on the environment, and the water quality in the eluates considering a wide range of parameters did not exceed the limits for road applications. Arroyo et al (2011) reported that the self-combustion potential was negligible as long as the amount of corrodible steel in the tire rubber is tightly controlled.…”

Xin, L.; He, J.; Liu, H., and Shen, Y., 2015. Potential of using cemented soil-tire chips mixture as construction fill: A laboratory study.Waste materials that are generated in large quantities, such as waste rubbers, plastics, and dredged soils, can potentially be reused as fill materials in construction projects. It will bring both economical and environmental benefits. This paper firstly presents a review on different methods of reusing scrap tires and waste soils in constructions. Then, a new method of using these two wastes as a fill material is proposed and experimentally evaluated. The material is formed by mixing waste soils, scrap tire chips, Portland cement, and water together in varying proportions. Isotropic compression and triaxial consolidated undrained compression tests were carried out. The geotechnical properties of the material with varying additions of different components are investigated. It is found that adding more tire chips in the material leads to an evident improvement in the undrained strength; while the compressibility of the specimens with 0-60% tire chips content (to dry soil by weight) does not change very much. The test results also manifest that increasing cement content is an effective way to reduce the compressibility and improve the undrained strength, indicating that the mechanical behavior of the material can be well controlled by adjusting the cement addition. Thanks to its advantageous features such as small compressibility and adjustable strength, the material is suitable for quaywall backfill and embankment fill in port or transportation constructions.
