Analisis Ionic Soil Stabilizer (Iss 2500) Terhadap Nilai Durabilitas Tanah Lempung Plastisitas Rendah Pada Perkerasan Jalan

Various methods of soil stabilizations in Indonesia are more increasingly used for quality improvement, one the is using chemically additive materials with ISS 2500 (Ionic Soil Stabilizer). This chemical solution able to cover particles through electro-chemical reactions, so that water content separated and cohesion among strengthened. However, unstable weather temperature changes (durability) forms rainfall heat influence cause defects especially road construction. In this reseach, tested was clay low plasticity from Karang Anyar region Lampung Selatan regency, mixed 0.9 ml optimum content. To enable reactions between 2500, treated 18 days durability treatment cycles addition; 0,2,4, 6 cycles. The laboratory results indicated CBR test cycle 0, 2, 4, obtained 8%, 7.6%, 5.7%, 5.1% respectively. value mix decreased regularly along given amounts additional overall stabilization an Stabilizer) can meet requirements Bina Marga as subgrade, because greater than 5% even though it treatment. material be alternative improvement subgrade.
