Abstract
The water content and energy applied during the compaction process affect the behavior of soils, particularly those containing clay. This also includes material mixtures such as polymer-enhanced bentonite-sand mixtures. The aim of this research is to carry out compaction tests and obtain parameters for the chitosan-bentonite-sand mixture material. The materials used are chitosan polymer, bentonite, and sand. The type of bentonite is calcium bentonite. Sand was taken from the Barito River, which is a common material used in construction and is available in large quantities. The two materials, chitosan and bentonite, are chemically mixed first, with a composition of 2% and 98% on a weight basis, respectively. This mixture was then added to sand with a composition of 10% chitosan-bentonite and 90% sand. Standard and elevated Proctor compaction tests were applied to the samples. The results showed the maximum dry density (MDD) and optimum moisture content (OMC) of standard Proctor compaction are 17.6 kN/m3 and 9.9%, respectively. The cohesion (c) and internal friction angle () obtained at the density are 7.79 kPa and 26.68°, with a permeability (k) of 1.437×10-11 m/s. For samples compacted using an elevated standard Proctor, MDD and OMC obtained are 17.7 kN/m3 and 5.89%, respectively. Other parameters are c of 9.11 kPa, of 23.03o, and k of 1.432×10-11 m/s.
