Soil improvement using steel slag waste on the value of the unconfined compressive strength of the soil (Case Study on Bojonegara Highway Serang Banten)
Daftar Isi:
- The highway is one of the infrastructures that people utilize to get around. However, there are instances when the infrastructure is destroyed owing to the nature of the terrain, vehicle loads, building work that does not match regulatory requirements, or other factors. This study was conducted on the Bojonegara Highway Banten, where the condition of the pavement construction, particularly on the subgrade, was damaged in a collapsed and holed state. Many reasons contributed to the damage, including soil conditions that did not meet specified requirements. As a result, it is essential to treat the soil by enhancing the subgrade by adding steel slag in order to achieve the required subgrade conditions. Subgrade improvement with steel slag evaluated using the unconfined compression strength test technique will result in a better subgrade mixed with steel slag. Steel slag is one of the ways industrial waste may be utilized to make something more valuable. In this research, steel slag will be used in various proportions ranging from 0 to 20% depending on the dry weight of the original soil. The UCT test yielded a value of 0.92 kg/cm2 for a 0 percent steel slag combination after 0 days of curing, while the maximum significant value was 2.40 kg/cm2 for a 20 percent steel slag combination after 28 days of curing. This study indicates that steel slag is a viable option for subgrade improvement.
