Field Soil Density Analysis Using the Sand Cone Method on the Segayam–Lebak Gedong Road Improvement Project, Ogan Ilir Regency

Abstract

Road infrastructure is crucial for the economy's smooth functioning, but its current state is largely due to natural and human factors, leading to increased traffic. Quality control is essential in road construction planning, focusing on aggregates, subgrade, and subbase layers. Factors such as water content, soil type, and compacted soil can affect soil density. A dense sub-base layer provides good bearing capacity, strengthening road construction. Improving road infrastructure is essential for maintaining the economy's lifeblood, supporting people's movement and influencing distribution and logistics activities. With the development of cities and technological advancements, national roads have grown, passing through provincial capitals and regency/city capitals. The Ogan Ilir Regency Government, through the Public Works and Housing Office, is working to meet community needs in road infrastructure, particularly in rural areas. However, many road conditions in Ogan Ilir Regency still need repairs and improvements. Road improvement in Ogan Ilir Regency should be carried out using good methods and optimal supervision. The sand cone method, which employs Ottawa sand as a parameter for soil density, is used to inspect the field density of the compacted soil layer or pavement layer.
