“…Generally, the residual water content of the soil sample decreased with the increase of compactness because the high-density soil sample has few pores. Similar conclusions were drawn by Pooni et al (2021). In addition, according to the results in Table 5, the sum of the residual squares of the fitted data is greater than 99%, indicating that the Van-Genuchten model can effectively predict the SWCC of expansive soil.…”

“…It is widely accepted that matric suction plays an important role in mechanical properties of the unsaturated soil, including resilient modulus and shear strength (Yao et al, 2018). Pooni et al (2021) applied the dewpoint potentiometer to measure the hydraulic behavior and the results showed the hydraulic variation has strong influence on the stabilization for an expansive subgrade. Therefore, the SWCC features of expansive soil must be investigated to scientifically and effectively evaluate the stability of the expansive soil slope (Dai et al, 2020).…”

“…where F, force (N); m, objects mass (kg); v, objects velocity (m/s); d, stopping distance (m). The soil material was obtained from a Melbourne land excavation site, which was used as engineering fill/ subgrade material in other recent soil-based experiments at the laboratory (Karami et al, 2021;Pooni et al, 2020;Pooni et al, 2021). Pooni et al (2020) explains that the soil is classified as a lean clay with sand (CL) and has a target maximum dry density (MDD) and optimum moisture content (OMC) of 1.62 g/cm 3 and 22.9%, respectively.…”

“…Additionally, in South Africa in 2011, around 35% of potential damage to structures was expected to occur by the action of expansive soil conditions ( 24 ). Moisture fluctuations are the primary cause of the propagation of distortion in pavements ( 22 ).…”

“…Expansive soils exhibit swell–shrink behavior, and structures constructed on these soils are ruined, with estimated annual reparation costs of $15 billion in the U.S.A. and £150 million in the UK ( 22 ). The worth of annual damage is estimated to be twice that of other types of natural devastation collectively.…”
