“…A combination of soil nailing and subsurface drainage mechanisms is described in Pun and Urciuoli (2008). In some scenarios, concrete or natural piles, columns, or nails may be able to be replaced with polymers, foams, or similar materials and composites that can fulfill the same purpose without the added weight and debris hazard of concrete (Selvakumar and Soundara 2019). Recycled Plastic Pins (RPPs) manufactured from plastic waste can be used in similar ways as a soil nailing application (Khan et al 2018).…”

Soil erosion of cover for earth covered magazine (ECM) storage presents a unique challenge to traditional embankment practices. Due to the strict guidelines on the necessary soil cover, as well as material allowed for use in erosion deterrence, many traditional soil erosion techniques are not allowable. This report investigates current soil erosion techniques and their applicability to magazine cover focusing on regulations, costs, and ease of implementation. The techniques investigated were based on currently used techniques from 2003 to the present but did not include researchonly stage mechanisms. The objective of this research effort was to investigate currently available erosion mitigation methods and their feasibility for ECM application. Main areas of concern for ECMs are envisioned to be cost, ease of implementation, and potential for added debris. Based on the reviewed literature, it appears that chemical or vegetative stabilization are likely the best methods for ECMs' erosion prevention. This assumes that simple soil compaction is not adequate, as it is otherwise generally the best approach. After a selection is made of a proposed solution to this issue, additional testing is suggested as a proof of erosion deterrence.

“…polypropylene/polyester fibres and expanded polystyrene (EPS)) were effective in reducing the swelling potential. Among other inclusion materials, EPS geofoam products are perform well in reducing the swelling potential due to its high compressibility characteristics [18,19]. Recently, Selvakumar and Soundara [11] have reported the innovative technique to reduce the swelling potential with the introduction of recycled geofoam granules column (used waste EPS blocks/beads) inclusions.…”

Expansive soils exhibit greater volume change with variation in moisture content. In this study, an attempt has been made to reuse the waste expanded polystyrene (EPS) beads as an environmentally friendly additive to mitigate the swelling potential. The swelling behaviour of expansive soil was examined with and without EPS geobeads inclusions. Several swell-compression tests were carried out on one-dimensional large consolidation apparatus (LCA) which can accommodate the California bearing ratio (CBR) mould. The swelling characteristics of remoulded soil specimens were evaluated with the addition of 0%, 0.25%, 0.5%, 0.75% and 1% geobeads content (gc) by the dry weight of the soil. The test result shows that the increase in gc from 0.25 to 1%, there is a gradual decrease in the vertical swelling potential (i.e. percent swell and swelling pressure). A higher recycled gc inclusion up to 1% could be preferable to reduce maximum swelling potential, where compressional deformations are not of primary concern.
