“…Furthermore, the values corresponding to those with the stone dust were higher compared to those with the bagasse ash, which implies that the soil stabilized with stone dust produced lower penetration-susceptibility. Considering the findings of Mousavi and Karamvand [42], the above observation may be justified with the possible chemical reaction between the soil particles and admixtures. The admixtures probably attributed to cementing effects on the soil, increasing their penetration resistance, thereby increasing the CBR; such cementing efficiency appeared to be more in the case of stone dust.…”

Soft ground improvement to provide stable foundations for infrastructure is national priority for most countries. Weak soil may initiate instability to foundations reducing their lifespan, which necessitates the adoption of a suitable soil stabilization method. Amongst various soil stabilization techniques, using appropriate admixtures is quite popular. The present study aims to investigate the suitability of bagasse ash and stone dust as the admixtures for stabilizing soft clay, in terms of compaction and penetration characteristics. The studies were conducted by means of a series of laboratory experimentations with standard Proctor compaction and CBR tests. From the test results it was observed that adding bagasse ash and stone dust significantly upgraded the compaction and penetration properties, specifically the values of optimum moisture content, maximum dry density and CBR. Comparison of test results with available data on similar experiments conducted by other researchers were also performed. Lastly, a study on the cost effectiveness for transport embankment construction with the treated soils, based on local site conditions in the study area of Assam, India, was carried out. The results are analyzed and interpreted, and the relevant conclusions are drawn therefrom. The limitations and recommendations for future research are also included.

“…They also used nano polymers such as CBR PLUS to stabilize granular bases, with results similar to those mentioned above, with increases of up to 6 times with the addition of 1% CBR PLUS and 9% silica sand; in terms of costs, it was concluded that a high initial investment is required, but low during its lifetime due to maintenance effects, according to the economic evaluation carried out [49], [50].…”

Nano materials are becoming more and more relevant in the construction of civil works, since they can be used as additions or additives to improve and stabilize asphalt concretes, hydraulic concretes, fine soils at the level of subgrade, sub-bases, bases and even for filters in water treatment. The present article intends to collect the different experiences in the use of nano materials, in order to stabilize or improve the mechanical and geotechnical properties of soils used in road construction, especially what has to do with the manufacture of nano fibers for use in soils; finding that its use in the field of roads is to be investigated and developed with different types of solutions, as the most studied are the carbon nano fibers

“…It is reported that when the compaction energy was increased, there was an increase in MDD and a decrease in OMC of soil [37][38][39]. The soil particles could be closer when increasing the compaction energy, leading to the reduction of void spaces between soil particles and the amount of water occupying the void spaces.…”

Phosphogypsum (PG) is a by-product of the production of fertilizers from phosphate ores, and it contains some harmful substances to the environment. Thus, it is necessary to stabilize/solidify pollutants when using PG as a filling material. The purpose of this study is to investigate and verify the use of PG as a filling material for a road base through laboratory tests for a case study in Vietnam. In this study, PG incorporated with fly ash was stabilized with cement and lime. The specimens of these mixtures were then prepared and cured under wet and dry conditions. The mechanical properties of specimen were investigated through the unconfined compressive strength (UCS), California bearing ratio (CBR), and modulus of elasticity. The physical property of this stabilization was examined using scanning electron microscopy. A toxicity characteristic leaching procedure test was also conducted to assess environmental impact. The results showed that when PG was replaced partially by other materials such as cement, fly ash, lime, or sand, the maximum dry densities of specimens were increased, and their optimum moisture contents were decreased. The inclusion of 10% of FA and 10% of cement or 20% of FA, 5% of lime, and 5% of cement significantly enhanced the UCS of specimens using PG at the ages of 28 days. The compressive strength under the dry condition was higher than that under the wet condition. Additionally, all mixtures showed a higher modulus of elasticity and CBR value than the requirement of road base material. The utilization of original PG can be successfully used as raw material in stabilization for applying in the pavement layers of road construction. The obtained results in the present work showed that the physico-mechanical properties in terms of unconfined compressive strength, modulus of elasticity, CBR of PG specimens could satisfy the requirement for the subgrade, subbase, or base course of road construction even when the content of PG comes up to 90%.
