“…However, among the three types of soil, there is a gray clay that is identified as containing montmorillonite minerals. Therefore, according to Munirwansyah and Munirwan [4], this type of soil is considered unsuitable for use as a road base layer. However, this soil can still be used if stabilization is carried out by adding additives that can improve the soil's properties.…”

Silty clay soil a quarry in Paya Tumpi, Kebayakan, West Aceh, is a source of backfill material that is often used for road construction in the area. This clay can be divided into three types based on its color, namely red, yellow, and gray. These three types of soil have bad properties that make them unsuitable for use as road base layers. Therefore, it is necessary to stabilize it using a mixture of volcanic ash taken from Wih Pesam and Bener Meriah. The purpose of this study was to evaluate the effect of mixing soil with volcanic ash on the shear strength of the soil. This research method involves compaction testing with a standard proctor and direct shear strength testing on a mixture of soil and volcanic ash. Variations in the addition of volcanic ash are 12.5%, 15%, 17.5%, and 20% of the dry weight of the soil. The results showed that the three soil types were included in the soil classification A-7-6 according to AASHTO, and the presence of minerals was detected in montmorillonite on gray soil. The addition of volcanic ash only increases the cohesion value of the gray soil in several variations of the mixture. The cohesion values for the various soil and volcanic ash mixtures of 0%, 12.5%, 15%, 17.5%, and 20% are as follows: for red soil, the cohesion values are 0.492, 0.408, 0.452, 0.088, respectively, and 0.344 in units of kg/cm2; for yellow soil, the cohesion values were 0.585, 0.562, 0.579, 0.243, and 0.327 in units of kg/cm2; while for gray soil, the cohesion values were 0.037, 0.453, 0.433, 0.206, and 0.031 in units of kg/cm2, respectively.

“…As for the improved soil, lime and cement are used as additives to mix with the plain soils, and then physical change and a chemical reaction happens, making the soil properties change. The interaction between additives and soil can be summarized as ion exchange, crystalline hardening, or carbonation [6] .…”

The poor fillings of embankments cause insufficient strength and excessive deformation to road subgrade. This study took a kind of onsite over-wet red clay soil as the research sample with lime and cement as additives to improve it, which could be used as the subgrade filling. Laboratory experiments scanning electron microscopy (SEM), California bearing ratio (CBR), water absorption, and unconfined compressive strength (UCS) were conducted to analyze the performance of the improved soil. The results showed that the improved clay soil had rich fibrous components, enabling the UCS values of the improved soil to reach greater than 0.6 MPa on average at 6% proportion by weight, which meant a higher strength compared to plain soil. The variation of maximum dry density value and optimum water content value on compaction curves indicated that the improved red clay soil could reduce its sensitivity to water, making it easy to be compacted. With the increase in additive proportion, the CBR values increased while water absorption potential decreased significantly, showing that the improved soil was likely to hold stable humidity for the subgrade without becoming too humid or too dry. The application to road subgrade in the field proved good practicability and performance of the improved clay soil.

“…Soil, as a material for construction, is applied as embankment material, which is collected from a borrow area, which is generally as clay cohesive soil. Clay behavior that is very sensitive to the water content addition and has a high shrink-swell characteristic as stated by [1]. Soil conditions that experience shrinkage can also affect the bearing capacity of the soil.…”

Abstract: The behavior of clay soil often becomes problematic for the building above it. One problem is its shrinking and swelling behavior which is affected by its water content, which also frequently influences the soil bearing of capacity in holding the load of the building above it. The powder from eggshell which abbreviated as ESP is a food industry waste that is high calcium and not often used for reprocessing. This experiment purposes is to know the effect of adding ESP as a stabilizing material in clay. Soil sample for laboratory testing was carried out from Cot Bagie Village, Blang Bintang, Aceh Besar District, and Aceh Province. From AASHTO classification system, the soil sample is A-7-5 (21) and from USCS system, is organic clay with high plasticity (OH). The percentages of ESP added are 0%, 3%, 6% and 9% of the dry weight of the clay for experiment on laboratory. The Atterberg Limit parameters commonly incline with ESP addition. Based on the standard Proctor test, the original soil has an Optimum Moisture Content (OMC) of 19.8% and a maximum dry unit weight (γ d max ) of 1.367 gr/cm 3 . Overall, adding ESP to the clay sample increases the mechanical properties of soil compared to the sample without ESP. Thus, the use of ESP for stabilization in this experiment can improve the bearing capacity, so that it is beneficial for construction in the field.
