The use of different marine residues found in the great biodiversity of the Peruvian coast, such as crushed mollusk shells or fan shells, can be used as mechanical stabilizers for clay soils due to a change in granulometry. In this article, we reviewed 74 research studies indexed in different databases such as Scopus, Scielo, Ebsco, Proquest, Springer Link, and ScienceDirect, whose publication has not exceeded seven years, with the objective of carrying out a systematic review of the use, effect and influence of marine debris as soil stabilizers. For this purpose, the analyses of the mechanical and also physical properties of such mixtures in different marine debris were reviewed compared to the various types of stabilizers currently used. These evaluated results indicate, that the Pacific razor clam shell offers a lower bearing capacity compared to the fan shell when stabilizing clayey soil. However, the shredded output of both types of marine debris can meet the need for clay subgrade stabilization. Based on the review, it was determined that the addition of different types of shredded marine debris reduces water absorption by capillarity, increasing the resistance and bearing capacity of the soil.

“…Además, con estas técnicas de aplicación de las nuevas tecnologías estabilizantes se pretende maximizar el desempeño del suelo, lo cual se busca reducción de polvo, conservación de finos y un aporte estructural [25], entre otras características como la impermeabilización en la muestra de un suelo [30]. Finalmente realizando un análisis mas profundo se logra destacar a distintas tecnologías por su incidencia en la mejora del "CBR", tal es el caso de la nanotecnología aplicada a la estabilización la cual incide en la mejora del cbr en un 8.60% [1], por otro lado, en la aplicación de sistemas, que inciden en una mejora de 12.4% [11], 12.8% [16], mejoras que son redundantes en otras tecnologías como 15.8% [14], 22% [27], 40% [3], 56.29% [7], 92% [6], asimismo con tecnologías de naturaleza biológica que inciden en una mejora de 42% -101% y 126% respectivamente, todas las tecnologías antes mencionadas inciden en un buen porcentaje de mejora en CBR, pero no tanto como la tecnología de cenizas volantes 138.31% [12] y la nueva tecnología "organosilano" 533% [18], puesto que realizando la comparación de porcentajes de mejora, esta última tecnología tendría la mayor incidencia en la estabilización de suelo.…”

The present work will include an investigation on the different uses of new technologies in stabilization, with the need to opt for an optimal terrain or soil for passability as evidenced in different parts of the world, which leads to the search for alternative solutions to This problem affects in one way or another the quality of life of people. The objective is to know about the use of these new technologies in the stabilization of soils designed for highways, based on a systematic review in the last 10 years, with data obtained through different sources such as Redalyc, ScienceDirect, Scopus, Scielo, Springer, among others. Since having land with excellent stabilization for road traffic guarantees safety and comfort from a good base, providing a better quality of life for people. The review was carried out under the IMRD -PRISMA methodology, considering the APPA writing and citation standards. The results of the evaluation of the use of new technologies and their effects on the soil for highways in the world detail that these materials have a positive impact on the characteristics of the treated soil, being the hydrophobic organosilane technology with an improvement index of 533%. in cbr stability.

“…However, their use as material for embankments and other works is less well documented. Particularly, quicklime has been used as a stabilizing product for thousands of years and it has been demonstrated that soils that do not meet initial technical requirements generated by the works, using this product improves the geomechanical characteristics [3].…”

In general, road construction requires the exploitation of large quantities of granular materials, and this generates significant economic and environmental impacts. The use of excavated materials for the construction of fills, embankments and reinforced earth retaining structures is an ideal solution to reduce the exploitation of raw materials. However, the use of excavated materials can be limited when these materials are fine-grained or have low mechanical specifications. In this sense, soils stabilized with quicklime have become a viable alternative for road construction, reducing the use of quarried materials. Although there are standards and techniques for the use of quicklime improved soils for pavements, today the evaluation process of these materials for embankment and fill construction is not well established. This paper presents the results of an investigation to determine the impact of quicklime soil stabilization on the design of embankments and retaining structures reinforced with geosynthetics. First, a road embankment is presented for which a sensitivity analysis was carried out in terms of geometry and volume of material required. Secondly, a mechanically stabilized wall with geosynthetics is presented in which a sensitivity analysis is performed in terms of the amount of geotextile reinforcement required. In both cases, the models were analyzed using the shear strength parameters of a residual soil of the Antioquian batholith in its natural state and stabilized with quicklime obtained in laboratory tests. A quicklime content of 2% and design processes according to Federal Highway Administration (FHWA) manuals were used. The results show that in the embankment a reduction in the volume of material is obtained when using stabilized soil of around 15%, since greater slopes and heights can be used with respect to the geometry of the soil in its natural state. In the case of the stabilized wall, a reduction of approximately 50% in the amount of geosynthetics required was observed, since with the case of stabilized soil it is possible to achieve layer reinforcements of greater thickness and lower strength than those obtained with the soil in its natural state. Both cases show that the implementation of soils stabilized with quicklime can be beneficial in terms of costs since a reduction in resources and materials can be achieved.
