“…Non-degrading fibers add to the effectiveness as treatments, and re-application of soil cover is not required. Other advantages include the ability to grow vegetation in addition to fibers and the ability to combine fibers with liquid or chemical stabilizers (Collins et al 2015).…”

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.

“…Ground improvement using fibers as a geosynthetic has received significant interest in geotechnical engineering research and practice. Applications of synthetic (or natural) fibers as a means of soil reinforcement may refer in the rehabilitation of locally failed slopes, the increase of the bearing capacity of weak soils, their use in backfill and embankment strengthening and the enhancement of their energy dissipation capacity, or in the mitigation of piping problems in hydraulic structures and preventing erosion [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

The use of polypropylene fibers as a geosynthetic in infrastructures is a promising ground treatment method with applications in the enhancement of the bearing capacity of foundations, slope rehabilitation, strengthening of backfills, as well as the improvement of the seismic behavior of geo-systems. Despite the large number of studies published in the literature investigating the properties of fiber-reinforced soils, less attention has been given in the evaluation of the dynamic properties of these composites, especially in examining damping characteristics and the influence of fiber inclusion and content. In the present study, the effect of polypropylene fiber inclusion on the small-strain damping ratio of sands with different gradations and various particle shapes was investigated through resonant column (macroscopic) experiments. The macroscopic test results suggested that the damping ratio of the mixtures tended to increase with increasing fiber content. Accordingly, a new expression was proposed which considers the influence of fiber content in the estimation of the small-strain damping of polypropylene fiber-sand mixtures and it can be complementary of damping modeling from small-to-medium strains based on previously developed expressions in the regime of medium strains. Additional insights were attempted to be obtained on the energy dissipation and contribution of fibers of these composite materials by performing grain-scale tests which further supported the macroscopic experimental test results. It was also attempted to interpret, based on the grain-scale tests results, the influence of fiber inclusion in a wide spectrum of properties for fiber-reinforced sands providing some general inferences on the contribution of polypropylene fibers on the constitutive behavior of granular materials.

“…Zezin et al [25] developed an electrolyte polymer that can effectively solve the problem of radioactive soil particle diffusion. Collins et al [26] found that a high molecular polymer can reduce the thickness of the hydrated film around the soil particles, which makes the connection of soil particles more compact.…”

Laboratory and Field Experiments on the Effect of Vinyl Acetate Polymer-Reinforced Soil

et al. 2019

Soil stabilizer can enhance the soil properties, which can improve ecological environmental problems such as soil erosion and slope instability. This study investigates the water-related and mechanical properties of soil stabilization using a polymer soil stabilizer solution synthesized from vinyl acetate polymer. The water properties test, mechanical properties test, durability test and seed growth test were carried out in the laboratory. Also, the effect of vinyl acetate polymer was verified by field tests. The results revealed that vinyl acetate polymer can enhance the water-retaining property, anti-erosion resistance, strength property and durability of soil, all of which increase with the increase of polymer concentration. At the same time, the polymer also has a certain promoting effect on vegetation growth. In addition, field tests proved that vinyl acetate polymer has good effects on soil engineering. These results could be applied as a reference for vinyl acetate polymer-improved soil engineering.
