“…Among others, the main clay minerals in expansive soils include illite, kaolinite, and montmorillonite (further on referred to as Mt). Owing to the hydrophilic nature and high dispersivity of the clay minerals, they cause high risk to the civil engineering foundations, to landslides triggering [2], and to the road subgrades [3] especially before bituminous coating as soil improvement additives or cold mixtures [4][5][6][7]. For practical implications in engineering, the treatment of expansive soils is imperative.…”

Calcium-based stabilizer materials (CSMs) exhibit pozzolanic properties which improve the properties of clayey soils by hydration, cation exchange, flocculation, pozzolanic reaction, and carbonation. In this comprehensive review, comprising over past three decades from 1990 to 2019, a mechanistic literature of expansive soil stabilization by incorporating CSMs is presented by reviewing 183 published research articles. The advantages and disadvantages of CSMs as the ground stabilizing agent are succinctly presented, and the major outcomes of physicochemical effects on soil properties are discussed in detail. After blending with CSM, the main and interaction effects on soil properties with focus on chemical processes such as X-ray fluorescence, X-ray diffraction analyses, and microstructure interaction by using scanning electron microscopy and thermogravimetric analysis have been reviewed in light of findings of past researchers. This work will help geotechnical engineers to opt for suitable CSM in the field of geoenvironmental engineering in committing to sustainable construction of civil engineering structures over expansive soils.

“…Kuna, Airey, and Thom (2016) reported that for better mixture performance filler (<0.075 mm) content has to be above 5%. Abdullah and Wahhab (2015) reported that the percentage of filler was more important when compared to the plasticity of filler in FBM. Sakr and Manke reported that FBMs with higher percentages of fines had higher stability values and reported that aggregate interlock has a larger effect compared to the viscosity of bitumen on stability values (Martinez-Arguelles, Giustozzi, Crispino, & Flintsch, 2015).…”

Abstract. In recent years, the use of foamed bitumen technology along with Reclaimed Asphalt Pavement is gaining popularity across the world. The mechanical response of foamed bitumen mixtures containing reclaimed asphalt pavement is significantly influenced by constituent material properties and aggregate gradation. This article presents results from a study where foamed bitumen mixtures conforming to Indian specifications were evaluated. For this purpose, foamed bitumen mixtures using a different percentage of reclaimed asphalt pavement and bitumens were prepared. Initially, the foaming characteristics of virgin bitumens were evaluated to optimize for optimum water content and foaming temperature. In the second stage, mixture design was conducted to optimize for foamed bitumen content in foamed bitumen mixtures containing a different percentage of reclaimed asphalt pavement. Finally, these foamed bitumen mixtures were evaluated for their mechanical properties. The results from this laboratory study indicated properties of foamed bitumen and foamed mixtures are significantly influenced by properties of bitumen, the quantity of bitumen, and reclaimed asphalt pavement. Among the different mixtures, a mixture containing 50% reclaimed asphalt pavement exhibited best results in resilient modulus and resistance to moisture damage tests. A mixture containing 80% reclaimed asphalt pavement also shows acceptable strength and resistance to water susceptibility. Thus, it is possible to design high-quality bituminous mixes using higher reclaimed asphalt pavement percentages, which meet the required volumetric and desired performance criteria.

“…In addition, as the content of salts increased, the Atterberg's limits and plasticity index decreased. Abdullah and Al-Abdul Wahhab (2015), (2018) have investigated stabilization of marginal soils (dune sand, sabkha and marl) covering most areas of Saudi Arabia's eastern and western parts. Using various stabilizers (sulfur foamed and emulsi ed sulfur asphalt), they studied the treatment of these soils and concluded that the stabilized soils could be used as the base layer in road construction.…”

The present work is to investigated the effect of sodium chloride (NaCl) on the behavior of semi-arid soils in the Najran region of Saudi Arabia. An experiment work was carried out to investigate how the addition of (NaCl) "salt" to semi-arid soils collected from Najran region affects the Atterberg limits, compaction characteristics, California Bearing Ratio (CBR) and shear strength. All tests were performed on soils samples collected from different areas in Najran region at various depths of 1.5, 3, and 4.5 m along soil profiles. Soils samples were tested alone and then compared with the same soils samples mixed with sodium chloride (salt) at different percentages of 5, 10, and 20% respectively. Using advanced techniques, such as the scanning electron microscope (SEM), energy dispersive x-ray analysis (EDX) and X-ray diffraction analysis (XRD), the process of stabilization was examined. The results showed that salt has a major impact on the geotechnical characteristics of semi-arid soils. With the addition of sodium chloride, the maximum dry density increased and the optimal water content decreased with the increase in the added salt percentage. The liquid and plastic limits and, in turn, plasticity index reduced as the added percentage of sodium chloride increased. Furthermore, significant increase in CBR and shear strength parameters was noticed. It is therefore concluded that, the sodium chloride could be a good stabilizing agent, particularly at 20% and could be used as a sub-base material in road construction. Technical and economic advantages arise from the implementation of NaCl.
