Abrasion, Compaction, Aggregate Absorption Specific Gravity TestingAbstract
The availability of mountain stone from Pepas Eheng Village, Barong Tongkok Subdistrict, West Kutai, is very abundant but has not been optimally utilized as a construction material. This study aims to test the characteristics and feasibility of crushed stone from the village as a road foundation layer material, in accordance with the 2018 Bina Marga General Specifications. Based on laboratory test results, this crushed stone meets the criteria as a class A foundation material with the following results: bulk specific gravity 2.68 gr/cm³, moisture content 0.59%, apparent specific gravity 2.72 gr/cm³, saturated specific gravity 2.69 gr/cm³, and abrasion 21.34%. In addition, the average fill weight of 1.62 gr/cm³ indicates this material is strong and stable enough to be used as a pavement foundation. The use of local crushed stone can reduce dependence on imported materials and support the sustainability of local resources
